8 Best Arch Supports for Flat Feet (June 2026) Top Picks

If you have flat feet, you know the daily struggle. Your feet ache after long shifts. Your arches collapse inward when you stand. And by evening, your knees and lower back are screaming for relief.

Our team has spent the last three months testing more than two dozen insoles to find the best arch supports for flat feet. We wore them through 10-hour retail shifts, weekend trail hikes, and daily training runs. We asked podiatrists which features actually matter. We dug through 200,000+ verified customer reviews.

The result is this guide. We’ve picked 8 of the best arch supports for flat feet you can buy right now in 2026, covering every budget, foot shape, and lifestyle. Whether you need help with overpronation, plantar fasciitis, or just want to stand all day without wincing, we have a recommendation for you.

Flat feet affect roughly 20-30% of the population, but the right arch support can completely change how your feet, knees, hips, and back feel. According to Dr. Naim Shaheed of the Ankle & Foot Centers of America, quality insoles do more than cushion. They stabilize your heel, distribute pressure evenly across the foot, and prevent the overpronation that causes most flat feet pain. If you want to understand what causes flat feet and related issues, our plantar fasciitis causes guide explains the connection.

Top 3 Picks for Best Arch Supports for Flat Feet

Best Arch Supports for Flat Feet in 2026: Quick Comparison

1. WALK HERO Plantar Fasciitis Relief Arch Support Insoles: Best Overall

The WALK HERO arch support insoles are our top pick for most people with flat feet. After testing them for 30 days across work boots, running shoes, and casual sneakers, I can say these are the most well-rounded option on this list. They balance cushion, support, and price in a way that few competitors manage.

What makes these arch supports stand out is the deep heel cup combined with premium EVA foam. The heel cup wraps your foot and locks it in place, which prevents the inward rolling that causes most flat feet pain. The EVA layer absorbs shock on hard surfaces, so 8-hour shifts on concrete feel much more bearable.

Our team especially liked the trim-to-fit design. If you have wider feet like me, you can leave them at full size. If you have narrower feet, you trim them down to fit loafers or dress shoes. The fabric top cover wicks moisture well, which is a nice bonus if you deal with sweaty feet on long days.

These insoles have over 74,000 reviews with an average 4.3 rating, making them the #1 bestseller in Foot Arch Supports on Amazon. That is not just hype. Real users consistently report relief from plantar fasciitis, flat feet, and general foot fatigue. One verified reviewer wrote, “I stand 9 hours a day as a cashier, and these are the only insoles that do not leave me limping by closing time.”

The main downside is the break-in period. New users should start with 2-3 hours per day and gradually work up to all-day wear. After about a week, your feet adjust and the support feels completely natural. I also found them too thick for my dress shoes, so I keep a separate pair of slimmer insoles for those.

Best for everyday work and casual shoes

WALK HERO designed these insoles for wider, high-volume shoes like work boots, basketball shoes, running shoes, and casual sneakers. They are not a good fit for low-profile loafers or narrow dress shoes. If your work shoes have removable factory insoles, these slot right in without needing extra room.

I tested them in both Red Wing work boots and New Balance running shoes. In both cases, the fit was snug, the arch support felt firm but not aggressive, and the heel cup kept my foot stable. For the price, you simply cannot beat this combination of features and reviews. If you are looking for a single, do-everything insole to start with, this is the one to try first.

Heel support that actually holds up

The deep heel cup is the standout feature. Many budget insoles have a flat heel that does nothing for stability. The WALK HERO design cradles the heel, which is critical for overpronation control. During my testing, I noticed less ankle fatigue at the end of long days compared to my old factory insoles.

Combined with the EVA foam shock absorption, this creates a noticeable reduction in foot impact when walking on hard floors. For anyone with flat feet who also deals with plantar fasciitis, this is a major benefit. Plantar fasciitis pain often comes from repetitive strain, and the right arch support can break that cycle.

2. WALK HERO Heavy Duty Pain Relief Insoles: Best for Heavier Users

If you weigh over 220 pounds, finding an insole that does not compress under your weight is tough. The WALK HERO Heavy Duty insoles solve that problem with a rigid orthopedic nylon arch that holds its shape no matter how much you weigh. Our team tested these in work boots and sneakers, and they delivered consistent support from day one.

The construction is impressive for the price. You get a 2mm high-density EVA foam base, a 3mm high-resilience OrthoLite middle layer, and a super soft PU heel cushion on top. That three-layer system provides both firmness under the arch and comfort under the heel. Most competing insoles in this price range offer only one or two layers.

I particularly appreciated the slimmer profile. Many heavy-duty insoles are bulky and force you to remove the factory insole plus loosen your laces. The WALK HERO design is thinner than most, which means it fits a wider range of shoes. I had no problem putting them in my casual sneakers without removing the existing insole first.

With 1,981 reviews averaging 4.4 stars, this is a newer product but one that has earned strong early feedback. 73% of reviewers give it 5 stars, which is unusually high for the heavy-duty category. Common themes in reviews include “immediate pain relief,” “no break-in discomfort,” and “better than my $200 custom orthotics.”

Designed for bigger bodies, longer days

These insoles are specifically built for users 220+ pounds. The orthopedic-grade materials and rigid arch support hold up to heavy daily use without flattening out. If you have been disappointed by insoles that feel supportive at first but compress within weeks, this design addresses that problem head-on.

The biomechanical shaping includes a deep heel cup and a contoured arch that matches the natural curve of your foot. Walking and standing feel more stable, and I noticed less knee and hip discomfort after a week of testing. The design also helps with overpronation, which is common in heavier users.

Worth the break-in period

Like all firm orthotic inserts, expect a 1-2 week break-in period. WALK HERO recommends starting with 2-3 hours per day and gradually increasing. By the end of week two, my feet felt completely adjusted. The arch support is firm but not aggressive, and the heel cushioning softens the impact on hard floors.

For anyone over 220 pounds who needs reliable arch support, this is a strong choice at a price well below custom orthotics. If you want a similar effect but a more established track record, the VALSOLE 250+ lbs insole is another option worth considering.

3. Superfeet All-Purpose Support High Arch Insoles (Green): Best Long-Term Durability

When it comes to long-term durability, no other insole on this list comes close to the Superfeet Green. Our team found multiple verified reviews from users who have worn the same pair for 10+ years. That is essentially unheard of in the insole world, where most products need replacement every 6-12 months.

The secret is Superfeet’s high-density closed-cell foam construction. Unlike cheaper EVA foam that compresses over time, this material holds its shape indefinitely. The trim-to-fit design lets you customize the insole to your exact shoe size, and the Moisturewick top cover helps reduce odor even after years of use.

I have been testing the Superfeet Green in my hiking boots and running shoes for over 60 days. The arch support is firmer than most competitors, which is exactly what flat feet need. The deep heel cup cradles your foot and prevents the inward rolling that causes most overpronation pain. After two months, the insoles look and feel almost brand new.

With 34,179 reviews averaging 4.4 stars, Superfeet has decades of proven performance. The brand is also widely recommended by podiatrists and specialty running stores. While the upfront cost is higher than most insoles, the cost-per-year is actually lower if they last a decade. That is the math our team kept coming back to during testing.

Firm support that does not compress

The biggest difference between Superfeet and budget insoles is firmness. These do not feel cushy in the way memory foam does. They feel structured, almost rigid. For flat feet, that is exactly what you want. Soft, squishy insoles may feel good for a week, but they do not provide the structural support your arch actually needs.

Dr. Naim Shaheed of the Ankle & Foot Centers of America has noted that firm arch support is generally better for flat feet than soft cushioning. The Superfeet design embodies this principle. If you have been using gel or memory foam insoles and not getting relief, switching to a firm, structured option like this often makes a major difference.

Best for roomy footwear

Superfeet insoles are thicker than most competitors, which means they work best in roomy footwear. Athletic shoes, work boots, hiking boots, and casual shoes with removable insoles are all good fits. Low-profile loafers and tight dress shoes are not ideal, as the insole will crowd your foot.

Trimming is required to dial in the fit. Superfeet includes clear instructions on the insole, and the process takes just a few minutes with sharp scissors. Once trimmed correctly, the fit is excellent and the support feels custom. If you want arch supports that will outlast every other option on the market, Superfeet Green is the clear winner.

4. PowerStep Pinnacle Insoles: Best Podiatrist-Recommended

PowerStep Pinnacle is the only insole on this list that is widely considered the #1 podiatrist-recommended brand. With 30,704 reviews averaging 4.5 stars, it has earned the trust of foot specialists and everyday users alike. Our team tested it for 45 days across athletic, work, and casual shoes.

What sets the PowerStep apart is the dual-layer cushioning system. The base layer is firm EVA foam for structural support. The top layer is a softer, more comfortable foam that absorbs shock. The result is an insole that feels supportive and comfortable at the same time, which is a hard balance to strike.

Made in the USA, the Pinnacle also comes with HSA and FSA eligibility. If you have a health savings account, you can use pre-tax dollars to buy these insoles, which effectively reduces the price significantly. The 30-day money-back guarantee adds another layer of confidence for first-time buyers.

Our team found the arch support to be moderate in firmness, which works well for most people with flat feet. It is not as aggressive as Superfeet, but it is firmer than budget options. The heel cup is deep enough to stabilize your foot without crowding the back of the shoe. We had no problem fitting the Pinnacle in running shoes, work boots, and casual sneakers.

Versatile across most shoe types

One of the best things about the PowerStep Pinnacle is versatility. It works in athletic shoes, walking shoes, running shoes, work shoes, and many casual shoes. As long as the factory insole is removable, the Pinnacle slots right in. No trimming is required, which is a plus if you dislike that step.

Users report significant relief from plantar fasciitis, heel spurs, flat feet, and overpronation. If you are dealing with multiple foot issues at once, the Pinnacle is a solid all-in-one solution. The 4.5-star rating across 30,000+ reviews tells you this is a product that delivers consistently.

Trusted by specialists and built to last

Podiatrist recommendation matters because specialists see thousands of patients and know which products actually work long-term. The Pinnacle has been on the market since 2002 and has only improved. The dual-layer cushioning holds up well over months of daily use, and the firm arch does not compress easily.

For anyone with flat feet who wants a proven, podiatrist-recommended option, the PowerStep Pinnacle is hard to beat. It is also one of the best running insoles for plantar fasciitis in our testing. Pair it with a quality pair of running shoes for flat feet and you have a winning combination.

5. PowerStep Pinnacle Maxx: Best for Overpronation

If you have flat feet combined with significant overpronation, the PowerStep Pinnacle Maxx is built for you. The defining feature is the slightly angled heel post, which actively prevents your foot from rolling inward. Our team found this makes a noticeable difference in knee and hip alignment during long walks and runs.

The Pinnacle Maxx is the thickest and most supportive model in the PowerStep Pinnacle line. With 19,238 reviews averaging 4.5 stars, it has earned a loyal following among users with serious overpronation issues. 75% of reviewers give it 5 stars, citing dramatic improvements in foot, knee, and hip pain.

The deep heel insert cradle is another standout feature. It locks your heel in place and prevents the lateral movement that worsens overpronation. Combined with the dual-layer cushioning and firm-but-flexible shell, the Maxx feels like a custom orthotic at a fraction of the price.

During our 30-day test, I noticed the biggest difference in knee alignment. My left knee tends to track inward when I am tired, and the angled heel post actively corrected this. By the end of the test, I had less knee soreness after runs and hikes. For anyone with knee or hip pain linked to flat feet, this is worth trying.

Specifically designed for overpronation

Overpronation is when your foot rolls excessively inward with each step. This common issue with flat feet puts extra stress on your ankles, knees, and hips. Standard insoles cushion the foot but do not correct the roll. The Pinnacle Maxx actively addresses the problem with its angled heel post and structured arch support.

It is also effective for posterior tibial tendonitis, a condition that often develops in people with flat feet. The tendon that supports your arch can become inflamed, and the right orthotic helps reduce that strain. Many users report significant relief from this condition after switching to the Maxx.

Need removable factory insoles

The Pinnacle Maxx is the thickest design in the Pinnacle line, so you will need shoes with removable factory insoles. Once you remove the factory insole, the Maxx drops in and fits snugly. We tested it in running shoes, work boots, and casual sneakers with no issues.

One note: the product listing shows limited stock at the time of writing, with only 2 pairs remaining at some retailers. If you are interested, do not wait. This is a top pick for anyone with serious overpronation, and it is one of the most recommended insoles for both flat feet and plantar fasciitis on Reddit.

6. Dr. Scholl’s Plantar Fasciitis Relief Orthotic Insoles: Best Budget Pick

For shoppers on a tight budget, the Dr. Scholl’s Plantar Fasciitis Relief insoles are a proven choice. With 55,004 reviews averaging 4.4 stars, this is one of the most popular insoles on Amazon. It is also one of the only products clinically proven to stop plantar fasciitis from coming back, according to the manufacturer.

Our team tested these for 30 days in casual sneakers and running shoes. The memory foam construction feels different from EVA or rigid orthotics. It is firmer than typical memory foam insoles, which is actually a good thing for flat feet. The deep heel cup and arch support work together to distribute pressure evenly across the foot.

One of the standout features is the trim-to-fit design. You simply cut the insole to match your shoe size using the printed guides on the back. The process takes a minute or two, and the result is a custom-looking fit. If you have multiple pairs of shoes in different sizes, you can trim a single insole to fit each one.

The most common positive feedback we found in reviews was “immediate pain relief” and “reduces morning pain.” Many users with plantar fasciitis report waking up with sharp heel pain, only to find that these insoles significantly reduce that first-step pain. That is a meaningful quality-of-life improvement.

Best for casual daily use

These insoles work best for casual daily use in sneakers, work shoes, and casual boots. If you are standing 9+ hours per day on hard surfaces, expect to replace them every 2-3 months. For lighter use, they typically last 6 months or more.

That is the trade-off at the budget price point. Premium insoles like Superfeet last 10+ years but cost 4-5x more upfront. If you are not ready to invest in a high-end pair, Dr. Scholl’s is a sensible starting point. You can always upgrade later once you confirm arch supports work for you.

Great entry point for first-time users

If you have never used orthotic insoles before, Dr. Scholl’s is a low-risk way to find out if arch supports help. The price makes it easy to try without commitment. The trim-to-fit design works in most shoes, and the proven clinical effectiveness means you are not gambling on an unknown brand.

For first-time buyers, anyone with mild flat feet, or shoppers who want a reliable backup pair, the Dr. Scholl’s Plantar Fasciitis Relief insoles are an excellent choice. They also work well for at-home plantar fasciitis treatment as part of a broader care plan.

7. Psveb Professional Heavy Duty Support Orthotics: Best for 230+ lbs

The Psveb Professional Heavy Duty insoles are a newer release from February 2026, but they have already earned 718 reviews with an impressive 4.5-star average. 79% of reviewers give them 5 stars, which is among the highest ratings on this list. Our team tested them in work boots and sneakers for 30 days.

The standout feature is the double PORON cushioning system. PORON is a high-performance foam used in industrial applications, and it absorbs shock far better than standard EVA foam. Combined with the Golden Triangle ergonomic design, which supports the forefoot, arch, and heel at three strategic points, the result is a balanced, stable feel that holds up under heavy use.

The deep U-shaped heel cup is another highlight. It locks your heel in place and prevents side-to-side slippage, which is critical for people over 230 pounds who put more force into every step. The PU layer on the bottom adds durability without sacrificing comfort.

During testing, I was impressed that the insoles did not flatten out after weeks of daily wear. That is a common complaint with cheaper insoles for heavier users. The Psveb design held its shape and continued to provide firm arch support even after 30 days of 8+ hour shifts on concrete floors.

Built for the heaviest daily use

If you are over 230 pounds and need arch supports that will not compress, the Psveb Professional is a strong option. The materials are designed for heavy use, and the construction holds up under punishing conditions. Many reviewers mention standing 9-10 hours per day on hard flooring and still getting solid support.

The trim-to-fit design lets you customize the insole to your shoe size. Cutting is straightforward with sharp scissors, and the printed guides on the insole make it easy. The breathable fabric top cover also helps with sweat and odor, which is a nice touch for all-day wear.

Three-point support for whole-foot stability

The Golden Triangle design is what really makes this insole different. By supporting the forefoot, arch, and heel simultaneously, the insole distributes pressure across the entire foot rather than concentrating it in one area. This is especially helpful for people with flat feet who experience forefoot pain in addition to arch pain.

The rigid arch support combined with the shock-absorbing PORON layer creates a unique balance. You get the firm structural support your arch needs, plus the cushioning that reduces impact on your joints. For heavier users, this combination is hard to find in a sub-$30 insole.

8. VALSOLE 250+ lbs Plantar Fasciitis High Arch Support: Best for Standing All Day

The VALSOLE 250+ lbs insole is our top pick for anyone who stands all day for work. Nurses, restaurant staff, retail workers, teachers, and warehouse employees put their feet through punishment. With 3,251 reviews averaging 4.4 stars, the VALSOLE has earned the trust of workers in some of the toughest jobs.

The design includes rearfoot and midfoot control points that reduce overpronation and stabilize the midfoot. Forefoot metatarsal pads cushion the ball of your foot, and Poron heel pads absorb shock at every step. The black rigid TPU support piece wraps the heel and supports the arch, which is a level of structure most insoles at this price do not offer.

Our team tested these in work boots and running shoes for 30 days. I particularly noticed the reduction in lower back pain. When your feet are properly supported, your knees, hips, and lower back do not have to compensate for poor alignment. By the end of the test, my evening back pain had decreased noticeably.

72% of reviewers give these insoles 5 stars. Common themes include “immediate relief,” “great for work boots,” and “better than my custom orthotics.” Several reviewers mention weighing 270-290 pounds and finding these insoles hold up under their weight, which is a meaningful endorsement.

Effective for multiple conditions

Beyond flat feet, the VALSOLE works well for Achilles tendonitis, ball of foot pain, arch drops, and overpronation. If you have multiple foot issues at once, this insole addresses several of them in a single product. The combination of high arch support, metatarsal padding, and shock absorption covers a lot of ground.

The trim-to-fit design works with most shoe types including work boots, hiking shoes, running shoes, and casual sneakers. We tested them in Red Wing and Timberland Pro work boots with no fit issues. If you wear work boots daily, these slot in and provide immediate support.

Adjustment period pays off

Like most firm orthotic insoles, expect a 3-7 day adjustment period. The manufacturer recommends starting with 2-3 hours per day and gradually working up. By the end of week two, the support feels natural and the foot adjusts to the new alignment.

One thing to note: some users report that the arch support decreases slightly after several weeks of heavy use. That is a common issue with insoles in this price range. If you need 24/7 support, the Superfeet Green is a longer-term investment. For a balance of price, support, and durability, the VALSOLE is a strong pick. It also pairs well with the best hiking shoes for flat feet if you spend time on the trails.

How We Chose the Best Arch Supports for Flat Feet

Our team spent three months testing over two dozen insoles for this guide. We wore each pair for at least 30 days across multiple shoe types including work boots, running shoes, and casual sneakers. We tracked comfort, support, durability, and fit throughout the testing period.

Beyond hands-on testing, we analyzed over 200,000 verified customer reviews across Amazon, Walmart, and specialty retailers. We cross-referenced this data with podiatrist recommendations and clinical research on orthotic effectiveness. We also consulted podiatry forums and Reddit communities like r/flatfeet and r/AdvancedRunning to understand what real users love and hate about each product.

To qualify for this list, every insole had to meet these criteria:

• Firm arch support: Gel and memory foam alone do not correct flat feet. We prioritized insoles with structured arch support that holds its shape.
• Deep heel cup: Heel stabilization is critical for overpronation control. Every pick includes a deep, well-shaped heel cup.
• Proven durability: We favored insoles with at least 500 reviews and consistent long-term feedback.
• Multiple size options: Flat feet come in many shapes. We chose insoles available in a wide range of sizes and widths.
• Real user results: Each product has hundreds or thousands of verified reviews reporting actual pain relief.

What to Look for in Arch Supports for Flat Feet

Not all arch supports are created equal. Here are the features that actually matter when shopping for the best arch supports for flat feet.

1. Firm arch support, not soft cushioning

The biggest mistake people make is choosing soft, gel-based insoles because they feel comfortable at first. Dr. Naim Shaheed of the Ankle & Foot Centers of America has emphasized that firm, structured arch support is almost always better for flat feet than soft cushioning. The arch needs actual support, not just padding.

Look for materials like EVA foam, polypropylene, or orthopedic-grade nylon. These materials hold their shape and provide the structural lift your collapsed arch needs. Soft gel insoles feel good for a week and then compress into uselessness.

2. Deep heel cup for stabilization

A deep heel cup is essential for controlling overpronation. The cup cradles your heel bone and prevents the inward rolling that causes most flat feet pain. The best insoles on this list all feature deep, well-shaped heel cups.

When testing insoles, press your thumb into the heel area. It should feel like a defined cup, not a flat surface. The deeper the cup, the more stability you get with every step.

3. Proper arch height for your foot

Arch height matters. If you have very flat feet, you may need a higher arch support to feel any benefit. If your arch is only slightly collapsed, a lower-profile support may be more comfortable.

Most OTC insoles come in low, medium, or high arch options. The WALK HERO and PowerStep models are good starting points for most people. The Superfeet Green is a high arch design that also works for flat feet due to its firm construction.

4. Trim-to-fit vs ready-to-wear

Trim-to-fit insoles require you to cut them to your shoe size, but they offer a more customized fit. Ready-to-wear insoles like the PowerStep Pinnacle ship in specific sizes and slot into your shoes with no cutting required.

Both approaches work well. Trim-to-fit gives you more control over the fit, while ready-to-wear saves time. Choose based on your preference and patience for a quick trimming process.

5. Durability and replacement cycle

Most OTC insoles last 6-12 months with daily use. Premium options like Superfeet can last 10+ years. Heavy-duty models like the WALK HERO Heavy Duty and VALSOLE typically last 6-9 months for users over 220 pounds.

Consider the cost-per-year, not just the upfront price. A $60 Superfeet pair that lasts 10 years is cheaper than a $20 pair you replace every 6 months. The break-even math depends on your body weight, daily use, and shoe environment.

OTC vs Custom Orthotics: Which Do You Need?

One of the most common questions we get is whether to buy over-the-counter (OTC) insoles or invest in custom orthotics from a podiatrist. The answer depends on the severity of your flat feet and the symptoms you are experiencing.

OTC insoles work well for most people with mild to moderate flat feet. They are affordable, readily available, and provide significant relief for the majority of users. Every product on this list is an OTC option, and all of them have hundreds or thousands of positive reviews.

Custom orthotics are made from a mold or 3D scan of your foot. They typically cost $495-$695 and are prescribed by a podiatrist. Custom orthotics are best for:

• Rigid flat feet that do not change shape with weight-bearing
• Severe overpronation causing chronic knee, hip, or back pain
• Diabetic foot conditions requiring precise pressure distribution
• Posterior tibial tendon dysfunction or other structural issues
• Patients who have tried multiple OTC insoles without relief

For most readers, OTC insoles are a great starting point. Try one of the picks on this list for 30-60 days. If you do not experience relief, schedule a consultation with a podiatrist to discuss custom orthotics. There is no reason to spend $500+ before trying the OTC options first.

How to Break In New Arch Supports

New orthotic insoles need a break-in period. Your feet have adapted to your current support (or lack thereof), and the new insoles will feel aggressive at first. Here is a simple break-in schedule:

1. Day 1-3: Wear for 2-3 hours per day, starting with low-impact activities.
2. Day 4-7: Increase to 4-5 hours per day, including some walking.
3. Day 8-14: Wear for 6-8 hours per day. By now, your feet should be adjusting.
4. Day 15+: Full-day wear is usually comfortable. If you still feel pain, the insole may not be the right fit for your foot.

During the break-in period, you may experience mild soreness as your feet adjust. This is normal. If you feel sharp pain, stop using the insoles and consult a podiatrist. Not every insole works for every foot.

Arch Height Self-Test Guide

Before buying insoles, it helps to know your arch type. Here is a simple wet test you can do at home:

1. Wet the bottom of your foot with water.
2. Step onto a piece of dark cardboard or thick paper.
3. Step off and examine the footprint.

Flat feet: The footprint shows nearly the entire sole of your foot, with little to no curve along the inside. You have low or no arch.

Normal arch: The footprint shows about half the width of your foot in the middle, with a clear curve along the inside.

High arch: The footprint shows a thin strip connecting the heel and ball of the foot, with a very pronounced curve or break in the middle.

If you have flat feet, look for insoles with medium to high arch support. Firm materials work better than soft cushioning. The picks on this list are all suitable for flat feet, with the Superfeet Green being the firmest option.

HSA/FSA Eligibility for Arch Supports

One important detail most buyers overlook: many arch supports qualify for HSA (Health Savings Account) and FSA (Flexible Spending Account) reimbursement. Insoles prescribed by a podiatrist for a specific medical condition are typically eligible, and some OTC options are also eligible.

PowerStep insoles are explicitly HSA and FSA eligible, which can save you 20-30% depending on your tax bracket. If you have an HSA or FSA, check the product listing for eligibility information. You may need to submit a receipt or Letter of Medical Necessity from your doctor.

This is a meaningful way to reduce the cost of premium insoles. The PowerStep Pinnacle at $49.99 is effectively $35-40 with HSA/FSA reimbursement, putting it in the same price range as mid-range OTC options.
