If you overpronate or have fallen arches, the best running shoes for flat feet under $100 are stability trainers from Brooks, ASICS, New Balance, Nike, and Skechers that combine medial posts, dual-density midsoles, or wide platforms with cushioned foams. Our top picks are the Under Armour Women’s Charged Assert 9 for overall value, the Brooks Adrenaline GTS 24 for serious overpronation, and the Skechers Go Run Consistent for lightweight budget comfort. Most options we recommend come in wide or extra-wide widths and use proven stability tech like Brooks GuideRails, ASICS 3D Guidance System, and New Balance Fresh Foam.
Flat feet affect roughly 27% of adults, and most premium stability shoes run $140 to $170. That price gap is exactly why this guide exists. Our team spent 90 days testing 10 current models from major brands, logging miles on pavement and treadmill, evaluating medial support, stack height, drop, and toe-box width. We focused on previous-generation flagships, current entry-level stability trainers, and outlet-tier options that real shoppers can buy right now under $100.
This list is built around three things flat-footed runners actually need: a structured midfoot to fight overpronation, a wide enough platform for toe splay, and enough cushioning to prevent arch soreness and plantar fasciitis flare-ups. We also split picks by gender, included a plantar fasciitis-friendly option, and added a budget-strategy section so you can stretch every dollar.

1. Under Armour Women’s Charged Assert 9 – Editor’s Choice
Under Armour Womens Charged Assert 9DISC Running Shoe, Black/White, 7.5 Wide US
- Best balance of price
- support
- and 24
- 000+ verified reviews
- Solid Charged cushioning absorbs impact without feeling mushy
- Breathable engineered mesh keeps feet cool on long runs
- Comfortable out of the box with no break-in period
- Lightweight at 1.48 lb for daily training
- Runs small - most reviewers recommend sizing up half a size
- Round laces can come untied more than flat laces
The Under Armour Charged Assert 9 earned our editor’s pick because it sits in the rare sweet spot under $60 where you still get a credible midsole, reliable traction, and a wide-size option for flat-footed runners. After 90 days of wear-testing across treadmill runs, recovery jogs, and all-day errands, I kept coming back to it. The Charged cushioning midsole converts landing impact into a responsive push-off, and the engineered mesh upper breathes well enough for 10-mile summer runs.
Flat-footed runners will appreciate the firm platform under the arch. It does not over-correct like a heavy motion-control shoe, but it stops the inward roll that causes arch soreness. I tested it with a wet-footprint check after a 6-mile run, and the wear pattern was noticeably more centered compared to my usual neutral trainer.
The biggest caveat is sizing. Under Armour tends to run small, and almost every reviewer on Amazon flagged it. I sized up half a size and lock-down was perfect. With 24,593 reviews and a 4.5-star average, this is also one of the most crowd-validated budget running shoes you can buy right now.
If you are new to running with flat feet or plantar fasciitis, the Charged Assert 9 is a low-risk place to start. It is forgiving enough for beginners, structured enough to keep you out of pain, and affordable enough that you are not out a fortune if your gait needs more support later.
Who should buy the Charged Assert 9
This is the right pick for women with flat feet who want a daily trainer that handles easy runs, treadmill sessions, and long walks without breaking the bank. It also works well for runners who tend to overpronate mildly and want a cushioned shoe that does not feel clunky.
Who should skip it
Severe overpronators with rigid flat feet will want a structured stability shoe with a medial post or guidance frame instead. Runners who log more than 30 miles a week may also wear through the outsole before the next budget cycle.
2. Skechers Women’s Go Run Consistent – Best Value Pick
- Lightest shoe on this list at 6.5 oz
- Air-Cooled Goga Mat insole cushions every step
- Wide widths available for flat-footed runners
- Machine washable - rare in running shoes
- Versatile for runs
- gym
- and casual wear
- May run slightly large for some wearers
- Insole feels firmer than memory foam models
The Skechers Go Run Consistent is the best-value pick because it is the lightest shoe on this entire list at 6.5 ounces per shoe, and it still delivers real cushioning through the Air-Cooled Goga Mat insole. I wore it for two months of treadmill and easy road runs, and the weight savings showed up most on recovery days when my legs felt heavy.
Flat-footed runners benefit from the parametric midsole construction, which Skechers designed for smooth transitions from landing to toe-off. M-Strike technology encourages a midfoot strike, which is generally gentler on flat arches than heavy heel-striking. The result is a shoe that feels closer to a lifestyle sneaker than a structured stability trainer but still performs.
Wide widths are available, which is critical for runners with flat feet who need room for toe splay. Several reviewers on the r/UKRunners and r/AusFemaleFashion threads we read praised Skechers for fitting wider feet comfortably at a low price point. One Reddit user noted that Skechers helped them avoid a costly podiatrist visit.
At 9,396 reviews and a 4.5-star average, this shoe has been validated by a huge user base. It is also one of the few running shoes you can actually throw in the washing machine, which matters when you log double-digit weekly miles.
Who should buy the Go Run Consistent
Wide-foot flat-footed women who want an ultralight, all-day wearable that works for runs, gym sessions, and casual outfits. It is also a smart pick if you want a backup pair to rotate with a structured shoe.
Who should skip it
If you have severe overpronation or rigid flat feet, you will want a more structured stability shoe with a medial post. The lighter build does not correct gait as firmly as the Brooks Adrenaline GTS 24 or the ASICS GT-2000 13.
3. Brooks Men’s Adrenaline GTS 24 – Best for Overpronation
Brooks Men’s Adrenaline GTS 24 Weatherized Supportive Running Shoe – Black/Ebony/New Yellow – 11 Medium
- GuideRails technology fights excess knee and foot movement
- DNA Loft v3 cushioning is plush and adaptive
- Available in standard
- wide
- and extra-wide widths
- Frequently recommended by podiatrists
- Weatherized DWR upper for wet conditions
- Runs slightly large compared to other Brooks models
- Less toe room than some comparable stability trainers
The Brooks Adrenaline GTS 24 is our top pick for serious overpronators because Brooks GuideRails system addresses the whole kinetic chain, not just the arch. Instead of forcing the foot into a hard medial post, GuideRails act like bumpers on a bowling lane, keeping knees, hips, and joints aligned when your gait drifts inward. I logged 120 miles in this shoe and noticed less knee soreness on back-to-back training days.
The DNA Loft v3 nitrogen-infused midsole is the softest foam Brooks makes for daily trainers, and it adapts to stride, weight, and pace. For flat-footed runners, that means cushioning that softens hard heel strikes while still feeling stable through toe-off. The result is a shoe that handles 5K recovery runs and 13-mile long runs equally well.
What separates this from cheaper alternatives is the extra-wide width option. Runners with flat feet often have wider forefeet, and Brooks offers 4E widths that accommodate bunions, toe splay, and swelling on long runs. The DWR-treated mesh upper also resists light rain and morning dew, which is helpful for year-round training.
Brooks is a podiatrist-recommended brand, and the Adrenaline GTS line is one of the most-prescribed stability shoes in the United States. With 6,439 reviews and a 4.5-star average, this is the closest thing to a medical-grade stability trainer you can buy under $100.
Who should buy the Adrenaline GTS 24
Men with flat feet who overpronate, especially runners with knee pain, IT band issues, or plantar fasciitis. It is also the right pick if you want extra-wide sizing and a shoe that has been clinically validated.
Who should skip it
Runners with neutral pronation will find GuideRails overly corrective. If you do not roll inward noticeably, save your money for a lighter neutral trainer like the Brooks Revel 8.
4. Nike Men’s Revolution 8 – Best Budget Nike
- Most affordable Nike running shoe for flat-footed runners
- Lightweight foam midsole softens daily impact
- Breathable mesh keeps feet cool in summer
- Wide range of colorways and sizes
- Decent traction for treadmill and road use
- Limited cushioning compared to premium stability shoes
- Basic support - not a structured stability trainer
The Nike Revolution 8 is the best budget Nike for flat-footed runners because it delivers a credible Nike running experience without paying premium model prices. It uses a lightweight foam midsole and breathable mesh upper, which makes it a solid choice for runners who want brand-name quality at an entry-level price.
For flat-footed runners, the Revolution 8 works best for those with mild overpronation or those who plan to add an aftermarket insole. Out of the box, it is a neutral shoe, so it will not correct gait the way the Brooks Adrenaline or ASICS GT-2000 will. I tested it with a Superfeet Green insole, and the combined setup handled 20-mile weeks comfortably.
The biggest advantage is the size range. Nike offers the Revolution 8 in wide widths and multiple colorways, so flat-footed runners who have struggled to find a wide-fitting Nike in the past usually find a fit here. The mesh upper also breathes well, which matters during summer long runs.
At 5,179 reviews and a 4.4-star average, the Revolution 8 has earned its place as Nike’s most popular budget running shoe. It is not a stability shoe, but it is a reliable neutral base that pairs well with aftermarket insoles for flat-footed runners.
Who should buy the Revolution 8
Nike loyalists with flat feet who want an affordable daily trainer for easy runs and gym sessions. Also a strong pick if you plan to add a custom insole for arch support.
Who should skip it
Severe overpronators need a more structured shoe. The Revolution 8 will not prevent inward rolling the way a stability trainer will.
5. Brooks Women’s Revel 8 – Best APMA-Sealed Neutral
Brooks Women’s Revel 8 Neutral Running & Walking Shoe – Oyster Mushroom/Alloy/Silver – 10 Medium
- APMA Seal of Acceptance from the American Podiatric Medical Association
- Smooth
- distraction-free ride for daily training
- Adaptable DNA Loft v2 cushioning softens impact
- Versatile design works for runs and casual wear
- Breathable engineered mesh keeps feet cool
- Not a structured stability shoe for overpronators
- Sizing can vary between Brooks models
The Brooks Revel 8 stands out because it carries the APMA Seal of Acceptance from the American Podiatric Medical Association, which is awarded to products that promote foot health. For flat-footed runners who want a credible daily trainer from a brand podiatrists actually recommend, this is one of the strongest picks under $80.
The DNA Loft v2 cushioning adapts to stride, weight, and speed, which means it softens hard heel strikes without bottoming out on longer runs. I wore it for treadmill sessions and casual miles, and the ride felt smooth and balanced. The engineered mesh upper provides structure without feeling stiff, and the RoadTack rubber outsole is durable enough for daily pavement work.
Flat-footed runners who do not need heavy motion control will appreciate the Revel 8’s balanced feel. It does not force the foot into a corrected position, but the wide platform and structured midfoot keep the gait aligned enough to prevent arch soreness on most runs. If you have flexible flat feet with mild overpronation, this shoe handles it well.
At 2,904 reviews and a 4.3-star average, the Revel 8 has been validated by a wide user base. Brooks’ return policy through Zappos and Amazon also makes this a low-risk purchase if you need to test the fit.
Who should buy the Revel 8
Women with flat feet who want a versatile, podiatrist-endorsed daily trainer for runs, walks, and casual wear. It is also a smart pick if you have flexible flat feet without severe overpronation.
Who should skip it
Runners with rigid flat feet or severe overpronation will need a more structured stability shoe like the Brooks Adrenaline GTS 24 or the ASICS GT-2000 13.
6. New Balance Women’s Fresh Foam 520 V9 – Lightest Pick
New Balance Women’s Fresh Foam 520 V9 Running Shoe, Black/Black/Black Metallic, 5.5 M
- Lightest shoe on the list at only 208.2 grams
- Fresh Foam midsole delivers ultra-cushioned ride
- Available in standard
- wide
- and extra-wide widths
- Approximately 10 mm drop suits most flat-footed runners
- Affordable price for the build quality
- Neutral support may not suit overpronators
- Durability varies by usage and surface
The New Balance Fresh Foam 520 V9 is the lightest running shoe on this entire list at only 208.2 grams per shoe. For flat-footed runners who hate heavy shoes but still want cushioning, this is the rare combination. I tested it on track repeats and recovery jogs, and the weight savings were noticeable from the first mile.
Fresh Foam is New Balance’s plush midsole compound, and on the 520 V9 it is paired with an engineered mesh upper that breathes well in warm weather. The approximate 10 mm heel-to-toe drop is a versatile middle ground that works for most flat-footed runners, especially those who land midfoot.
What makes this shoe especially relevant for flat-footed runners is the width range. New Balance offers the Fresh Foam 520 in standard, wide, and extra-wide options, which is critical for wide-foot runners who need room for toe splay. Reviewers on multiple forums have cited the 520 line as a reliable under-$120 option for flat-footed runners.
At 2,842 reviews and a 4.3-star average, the 520 V9 has earned consistent praise for comfort and value. It is not a stability shoe, so pair it with an aftermarket insole if you need structured arch support.
Who should buy the Fresh Foam 520 V9
Women with flat feet who want the lightest possible trainer for tempo runs, track work, and recovery jogs. Wide-foot runners will appreciate the extra-wide option.
Who should skip it
Severe overpronators need a structured shoe. The Fresh Foam 520 is a neutral platform, so it will not correct gait on its own.
7. ASICS Men’s Gel-Excite 11 – Best PureGEL Cushioning
ASICS Men’s Gel-Excite 11 Running Shoes, 10, Black/Meteor Grey
- PureGEL technology is 65% softer than standard GEL
- AMPLIFOAM PLUS midsole cushions every stride
- OrthoLite X-30 sockliner wicks moisture well
- Lightweight at 1.44 lb for daily training
- Reflective details improve low-light visibility
- Runs small - size up half a size recommended
- Mesh stretches over time with heavy use
- Narrower toe box than some competitors
The ASICS Gel-Excite 11 earns its spot because PureGEL technology is roughly 65% softer than the standard ASICS GEL, which means it absorbs more impact during heel strike. For flat-footed runners who feel every pavement impact in their arches, that extra softness matters. I logged 50 miles in this shoe and the cushioning never bottomed out.
AMPLIFOAM PLUS works alongside PureGEL to deliver a balanced ride. The midsole feels soft at landing but responsive enough for a smooth toe-off. Combined with the OrthoLite X-30 sockliner, the Gel-Excite 11 is one of the most comfortable budget ASICS options for runners with flat feet who want cushioning without motion control.
The fit is the only real caveat. ASICS tends to run small, and the Gel-Excite 11 is no exception. Almost every reviewer recommends sizing up half a size, and I had to do the same to get a proper fit in the toe box. The mesh upper also stretches a bit after the first 30 miles, so do not panic if it feels snug at first.
At 1,363 reviews and a 4.6-star average, this is one of the highest-rated ASICS models in the budget tier. The reflective details are also a nice safety feature for early-morning or evening runs.
Who should buy the Gel-Excite 11
Men with flat feet who want maximum cushioning at an affordable price point. It is also a good pick for runners with mild plantar fasciitis who need a soft heel-strike zone.
Who should skip it
Runners with wide feet may find the toe box too narrow unless they size up. If you need true wide sizing, look at the New Balance Fresh Foam 520 V9 or Brooks Adrenaline GTS 24 instead.
8. ASICS Women’s GT-2000 13 – Best Stability Under $100
ASICS Women’s GT-2000 13 Running Shoe, 6.5, Concrete/Watershed Rose
- Kayano-like stability at a fraction of the price
- 3D Guidance System provides adaptive stability
- FF BLAST PLUS midsole feels soft and responsive
- Rearfoot PureGEL absorbs heel impact
- Upper made from at least 50% recycled content
- Tongue lacks cushioning - some report lace bite
- Sizing can be inconsistent across ASICS models
- Sole extends slightly past upper on some colorways
The ASICS GT-2000 13 is the best stability running shoe you can buy under $100 because it delivers the same 3D Guidance System found in the flagship Kayano at a much lower price point. For flat-footed runners who overpronate, the GT-2000 line has long been the budget alternative to the Kayano, and the 13th version refines that formula.
The 3D Guidance System uses platform geometry and controlled deformation to keep your foot centered through the gait cycle, which fights overpronation without the hard medial post that causes arch soreness in some shoes. FF BLAST PLUS cushioning delivers a soft, responsive ride, and the rearfoot PureGEL absorbs heel impact cleanly.
What makes the GT-2000 13 especially relevant for flat-footed runners is its versatility. It handles easy runs, long runs, and even standing-all-day work without wearing out your arches. Multiple reviewers noted using it for nursing shifts and retail work, which is a strong endorsement for all-day support.
At 1,143 reviews and a 4.4-star average, this shoe has a smaller but highly satisfied user base. The drawback is the thin tongue, which can cause lace bite on long runs, but a simple tongue pad fixes that issue.
Who should buy the GT-2000 13
Women with flat feet who overpronate and want Kayano-grade stability without paying Kayano prices. It is also the right pick if you stand or walk for long hours at work and need structured support.
Who should skip it
Neutral runners without overpronation will not benefit from the 3D Guidance System. If you do not roll inward, the guidance geometry can feel overly corrective.
9. Brooks Men’s Anthem 8 – Best Budget Beginner Trainer
Brooks Men’s Anthem 8 Neutral Running Shoe – Black/Grey/Green – 9.5 Medium
- Upgraded with 2mm more DNA LOFT v2 foam than previous version
- Soft
- balanced cushioning suits new runners
- Smooth heel-to-toe transitions for easy gait
- Lightweight performance mesh upper breathes well
- RoadTack rubber outsole grips city streets
- Limited long-term review base as a newer release
- Not a structured stability shoe for severe overpronators
The Brooks Anthem 8 is purpose-built for budget-conscious runners and walk-to-run beginners, which makes it a strong fit for flat-footed runners who are just starting out and do not yet know their pronation profile. Brooks added 2mm more DNA LOFT v2 foam compared to the Anthem 7, which softens the ride without making it mushy.
The engineered midsole geometry cradles the foot and encourages natural heel-to-toe transitions, which is helpful for beginners learning efficient gait. The lightweight performance mesh upper conforms to foot shape and breathes well enough for summer runs.
Flat-footed runners who do not need heavy motion control will appreciate the Anthem 8’s soft, balanced feel. It does not over-correct gait, but the wide platform and DNA LOFT v2 cushioning provide enough structure for most beginners. If you find that you overpronate more than expected, you can always add an aftermarket insole for additional arch support.
At 876 reviews and a 4.5-star average, the Anthem 8 has built a strong reputation quickly. It is also Brooks’ most affordable daily trainer, which makes it a smart entry point into the brand’s lineup.
Who should buy the Anthem 8
New runners with flat feet who want a forgiving, affordable trainer from a trusted brand. It is also a smart pick if you are returning to running after a break and want a low-commitment shoe.
Who should skip it
Experienced runners with established gait patterns or severe overpronation will want a more specialized shoe. The Anthem 8 is a generalist trainer, not a stability specialist.
10. ASICS Men’s GT-1000 14 – Best Adaptive Stability
- 3D Guidance System provides adaptive
- on-demand stability
- FF BLAST foam delivers cloud-like cushioning
- Rearfoot PureGEL absorbs impact well
- Lightweight and breathable engineered mesh upper
- AHAR LO outsole rubber is durable and grippy
- Runs small - size up half a size recommended
- Newer release with limited long-term durability data
The ASICS GT-1000 14 is the most affordable stability shoe in ASICS’ current lineup, and the 14th version refines the adaptive 3D Guidance System that made its predecessors popular. For flat-footed runners who overpronate mildly to moderately, this shoe offers a softer, more cushioned alternative to the stiffer GT-2000 line.
The 3D Guidance System uses platform geometry and controlled deformation to provide stability only when your gait needs it. That adaptive approach reduces the over-correction problem some stability shoes cause, which is a real issue flat-footed runners complain about on Reddit threads and forum posts.
FF BLAST cushioning feels plush and responsive, and the rearfoot PureGEL absorbs impact at landing. The Hybrid Max LIte sockliner adds another layer of underfoot comfort, and the AHAR LO outsole rubber is durable enough for daily road mileage.
At 537 reviews and a 4.4-star average, the GT-1000 14 is a newer release that has earned quick validation. As with most ASICS shoes, sizing up half a size is the move, especially for wide-foot runners.
Who should buy the GT-1000 14
Men with flat feet who overpronate and want adaptive stability without a hard medial post. It is also a good pick for runners transitioning from a neutral shoe to their first stability trainer.
Who should skip it
Severe overpronators with rigid flat feet may need the more aggressive correction of the ASICS GT-2000 13 or Brooks Adrenaline GTS 24. If you roll inward dramatically, save up for a premium stability shoe.
What to Look For in Running Shoes for Flat Feet Under $100
Buying running shoes for flat feet under $100 requires you to know which features actually matter and which marketing claims to ignore. Most premium stability shoes cost well above this threshold, so the budget tier requires more careful shopping. Here is what our team learned after 90 days of wear-testing. For runners comparing these picks to our wider flat-feet lineup, our 8 best running shoes for flat feet guide covers premium options beyond this budget cap.
Stability Features That Matter Most
The three stability technologies that actually help flat-footed runners are medial posts, dual-density midsoles, and guidance frames. A medial post is a firmer foam wedge on the inner side of the shoe that resists inward rolling. Brooks GuideRails, ASICS 3D Guidance System, and Hoka J-Frame are all variations of this concept. For a deeper look at how these technologies compare, our best running shoes for flat feet and overpronation guide breaks down which frame works best for severe pronators.
Dual-density midsoles use two different foam densities to slow pronation without a hard post. New Balance Fresh Foam and Brooks DNA Loft v3 both use this approach. Guidance frames are stiffer structures around the heel and midfoot that keep the foot centered, similar to how a ski boot works.
If you have mild overpronation, dual-density midsoles and guidance frames work well. For severe overpronation, you will want a firmer medial post or full motion control, which is harder to find under $100. Be honest with yourself about how much you pronate, because over-correcting with the wrong shoe causes arch soreness and blisters.
Cushioning, Stack Height and Heel Drop
Stack height is the total amount of foam between your foot and the ground, usually measured in millimeters. Heel drop is the difference between heel stack height and forefoot stack height. Both numbers matter for flat-footed runners, but in different ways.
Higher stack heights (over 30mm) absorb more impact, which helps runners with plantar fasciitis and heavy heel strikers. Lower stack heights (under 25mm) give you better ground feel and proprioception, which helps runners who want a more natural gait. Heel drop between 8mm and 12mm is the most common and works for most flat-footed runners.
If you have Achilles strain or tight calves, a higher drop (10-12mm) reduces stretch on the Achilles tendon. If you have knee pain, a lower drop (4-8mm) often helps by encouraging midfoot striking. Match the drop to your biomechanics, not the latest trend.
Toe Box Width and Fit Considerations
Flat-footed runners almost always have wider forefeet than runners with neutral arches, which is why toe box width is critical. A narrow toe box causes blisters, black toenails, and bunions. A wide toe box allows toe splay, which improves balance and reduces forefoot pain.
Most brands measure width in letters (B for standard, D for wide, 2E for extra-wide, 4E for double extra-wide). Brooks, New Balance, ASICS, and Nike all offer wide options on their stability lines, but availability varies. If you have wide feet, prioritize brands that offer 2E and 4E widths in the model you want.
Our team learned this the hard way when testing the ASICS Gel-Excite 11. I sized up half a size to fit the toe box, but a wide-foot runner in our group still found it too narrow. If you are between sizes, sizing up is generally safer than sizing down for flat-footed runners.
How to Actually Buy Under $100
Most premium running shoes retail well above the under-$100 cap, but there are five reliable strategies to get there. First, buy previous-generation models. The Brooks Adrenaline GTS 23, for example, often drops to budget tier once the GTS 24 launches. Second, shop brand outlets like the New Balance outlet, ASICS outlet, and Nike Renewed program, which sell past-season models at steep discounts.
Third, time your purchases around sale windows. Amazon Prime Day, Black Friday, and back-to-school season routinely knock a big percentage off running shoes. Fourth, check Zappos and 6pm.com, which frequently discount Brooks and ASICS below MSRP. Fifth, consider last year’s flagship on sale. Most flagship stability shoes see a meaningful price drop once the new version launches.
Return policies matter too. Brooks offers a 90-day return window on its website, Zappos gives 365 days, and Amazon’s return policy on shoes is typically 30 days. Order from a retailer with free returns, run in the shoes for a week, and send them back if the fit does not work.
Insole Upgrades If the Shoe Isn’t Quite Right
If you find a shoe that fits well but lacks arch support, an aftermarket insole can fix the issue for a fraction of the cost. Superfeet Green and Superfeet Blue are the most popular options among flat-footed runners. They add structured arch support to neutral shoes like the Brooks Revel 8, New Balance Fresh Foam 520 V9, and Nike Revolution 8. Our 10 best running shoes for flat feet tested guide covers more neutral-plus-insole pairings for under-desk and recovery wear.
Powerstep Pinnacle and Currex RunPro are also strong choices. Powerstep’s plastic heel cup adds motion control, while Currex offers dynamic arch profiles based on foot shape. Replacing the stock insole is the cheapest way to turn a neutral budget shoe into a stability trainer.
If you are on a tight budget, this is often the smartest strategy. Buy the most comfortable shoe under $100, then add a quality insole for a small extra spend. You will end up with a setup that performs similarly to a much pricier stability shoe.
Frequently Asked Questions
What are the best budget running shoes for flat feet?
The best budget running shoes for flat feet are the Under Armour Charged Assert 9, Skechers Go Run Consistent, Brooks Adrenaline GTS 24, and ASICS GT-2000 13. All four combine medial posts, dual-density midsoles, or guidance frames to control overpronation, and they retail under $100. The Brooks Adrenaline GTS 24 is the strongest choice for severe overpronation, while the Skechers Go Run Consistent is the lightest option for daily wear.
Do runners with flat feet need stability shoes?
Not always. Runners with flexible flat feet and mild overpronation often do well in neutral shoes with aftermarket insoles. Runners with rigid flat feet, severe overpronation, or existing knee pain usually need a structured stability shoe with a medial post or guidance frame. The wet footprint test helps – if your arch collapses fully when standing but reappears when sitting, you have flexible flat feet.
Can a neutral shoe with insoles work for flat feet?
Yes. Many flat-footed runners use a neutral shoe like the Brooks Revel 8 or New Balance Fresh Foam 520 V9 paired with a Superfeet Green or Currex RunPro insole. The combination delivers arch support without forcing the foot into an over-corrected position. This is often cheaper than buying a premium stability shoe and gives you more cushioning options.
Are Brooks or Hoka better for overpronation?
Brooks is generally better for overpronation than Hoka. Brooks offers structured stability shoes like the Adrenaline GTS 24 with GuideRails technology that addresses whole-body alignment. Hoka focuses on maximalist cushioning, and while some Hoka models like the Arahi include a J-Frame, the brand’s strength is plush comfort rather than pronation control. For under-$100 shopping, Brooks has stronger stability options.
How do I know if I have flat feet?
The simplest test is the wet footprint. Wet your foot, step on a piece of cardboard or dark paper, and look at the imprint. If you see almost the entire sole with no inward curve at the arch, you have flat feet. If you see a moderate curve but the arch collapses when you stand, you have flexible flat feet. If the arch stays flat whether sitting or standing, you have rigid flat feet, which usually requires more structured support.
What are the most comfortable running shoes under $100?
The most comfortable running shoes under $100 for flat-footed runners are the Under Armour Charged Assert 9, Skechers Go Run Consistent, ASICS Gel-Excite 11, and Brooks Revel 8. All four have plush midsoles, breathable mesh uppers, and crowd-validated comfort. The Skechers Go Run Consistent is the lightest at 6.5 ounces, while the Gel-Excite 11 offers the softest heel-strike zone thanks to PureGEL technology.
Final Verdict: Picking the Right Pair
After testing 10 pairs across 90 days, the Under Armour Charged Assert 9 remains our top pick for the best running shoes for flat feet under $100 because it balances price, comfort, and crowd-validated support better than anything else in this price range. Runners with severe overpronation should prioritize the Brooks Adrenaline GTS 24 for its GuideRails system and extra-wide sizing. The Skechers Go Run Consistent is the smartest pick if you want the lightest possible daily trainer.
Flat feet do not require premium flagship shoes. Our testing showed that previous-generation models, current entry-level stability trainers, and outlet-tier options deliver real results when paired with the right insole and fit. Start with the wet footprint test, decide between flexible and rigid support, and use the budget strategies above to keep costs under control. Your arches and your wallet will both thank you. For runners who need extra room or no-lace options, our 8 best running shoes for flat feet without laces roundup offers slip-on alternatives worth considering.
