You have been putting off using your FSA dollars all year, and now the deadline is approaching. You know the money disappears if you do not spend it, but you are not sure which foot products actually qualify — and which ones are worth buying even if they do.

In our clinic, we see patients every December scrambling to spend their remaining flexible spending account (FSA) or health savings account (HSA) funds before the deadline. The good news is that many of the products we recommend for plantar fasciitis, neuropathy, flat feet, and other conditions are FSA/HSA eligible. This guide breaks down exactly what qualifies, what gives you the best value per dollar, and what you should skip.

What FSA and HSA Funds Actually Cover for Feet

FSA and HSA accounts cover medically necessary foot products when prescribed or recommended by a healthcare provider for a diagnosed condition. The IRS defines eligible expenses as those that diagnose, cure, mitigate, treat, or prevent disease. For foot care, this includes custom orthotics, therapeutic insoles, compression stockings, topical medications, night splints, walking boots, and diabetic foot care supplies. Over-the-counter products like insoles and pain relief gels became eligible without a prescription after the CARES Act of 2020, making it easier than ever to use your tax-free funds on foot health.

In our practice, we provide letters of medical necessity for patients who need documentation for their FSA/HSA claims. Most products on this page qualify automatically, but having a podiatrist’s recommendation strengthens any claim your benefits administrator might question.

Custom Orthotics: The Highest-Value FSA Purchase

Custom orthotics are the single highest-value FSA/HSA purchase you can make for your feet. A pair of prescription orthotics costs $400–$600 and lasts 3–5 years, making them one of the most cost-effective treatments per year of use. They address the structural root cause of plantar fasciitis, flat feet, bunions, and metatarsalgia rather than just masking symptoms. In our clinic, we use 3D digital scanning to capture your exact foot architecture, and the orthotics are manufactured to correct your specific biomechanical issues.

If you have remaining FSA funds and any ongoing foot pain, custom orthotics should be your first call. Learn about our custom orthotic process →. Medicare Part B covers custom orthotics for qualifying conditions, and most PPO plans reimburse when medically indicated.

OTC Therapeutic Insoles With a Letter of Medical Necessity

Over-the-counter therapeutic insoles qualify for FSA/HSA reimbursement when used for a medical condition. Since the CARES Act, you no longer need a prescription for OTC medical products — but having a letter of medical necessity from your podiatrist makes claims smoother. The best OTC insoles provide genuine medical-grade arch support, not just cushioning.

PowerStep Pinnacle — Best Overall OTC Insole ($26–$45)

The OTC orthotic I recommend most in our clinic. PowerStep Pinnacle delivers medical-grade arch support at a fraction of custom orthotic cost. The semi-rigid shell provides genuine biomechanical correction rather than just cushioning, which is why it works for plantar fasciitis, flat feet, and metatarsalgia. The dual-layer cushioning absorbs impact at heel strike while the contoured shape cradles the arch. Most patients notice improvement within 2–3 weeks of consistent wear.

Best for: Plantar fasciitis, flat feet, overpronation, general arch support. Not ideal for: Very high arches (consider PowerStep Pulse) or severe flat feet (PowerStep Maxx provides firmer correction).

PowerStep Maxx — Best for Severe Flat Feet ($30–$45)

PowerStep Maxx adds a stronger motion-control shell and deeper heel cup for patients with significant overpronation. In our clinic, we recommend Maxx when the standard Pinnacle does not provide enough correction — typically for patients with stage II posterior tibial tendon dysfunction or BMI over 30. The firmer arch support prevents the excessive inward roll that leads to knee pain, shin splints, and plantar fasciitis in flat-footed patients.

Best for: Severe flat feet, stage II PTTD, heavy overpronation, patients over 200 lbs. Not ideal for: Normal or high arches (too much correction causes lateral foot pain).

PowerStep Pulse — Best for Active Patients ($35–$45)

PowerStep Pulse combines the Pinnacle’s arch support with a running-specific heel geometry and lighter materials. If you are using FSA/HSA funds and you run, walk for exercise, or work on your feet all day, Pulse gives you the therapeutic arch support plus energy return that standard insoles lack. The anti-microbial top cover handles the sweat from extended activity.

Best for: Runners with plantar fasciitis, walking enthusiasts, active lifestyles. Not ideal for: Dress shoes or tight-fitting footwear (too thick).

Medical Compression Socks for Circulation

Medical compression socks are FSA/HSA eligible when used for diagnosed conditions including venous insufficiency, lymphedema, diabetic neuropathy, post-surgical swelling, and occupational edema. Graduated compression (15–20 mmHg or 20–30 mmHg) improves venous return and reduces fluid pooling in the lower extremities. In our clinic, we recommend compression stockings for patients who stand or sit for extended periods, pregnant women with swollen feet, and post-operative patients.

DASS Medical Compression Socks — Graduated Support ($25–$35)

Graduated medical compression socks are an option for patients needing daily compression support — recommend based on fit and patient feedback. DASS offers both 15–20 mmHg (mild, great for daily prevention and travel) and 20–30 mmHg (moderate, for diagnosed venous insufficiency and post-surgical recovery). The graduated compression is tightest at the ankle and decreases up the calf, which is the clinically proven pattern for improving venous return.

Best for: Swollen feet and ankles, post-surgical recovery, long flights, standing occupations, diabetic foot care. Not ideal for: Peripheral arterial disease without physician clearance (compression can worsen arterial insufficiency).

Topical Pain Relief Products

Topical pain relief products became FSA/HSA eligible without a prescription after the CARES Act of 2020. These are among the most practical FSA purchases because they are consumable — you will use them up and need replacements, making them excellent for spending down remaining balances. The key is choosing products with clinically proven active ingredients rather than marketing-driven formulations.

Doctor Hoy’s Natural Pain Relief Gel — Best Topical for Foot Pain ($15–$25)

Natural topical pain relief I use in our clinic. Doctor Hoy’s combines arnica and camphor in a clean formula that provides genuine pain relief without the synthetic chemicals found in many alternatives. Apply directly to the plantar fascia, Achilles tendon, or arthritic joints 3–4 times daily. The natural formula is particularly important for patients with sensitive skin or chemical sensitivities. We switched our entire practice from Doctor Hoy’s Natural Pain Relief Gel to Doctor Hoy’s because the clinical results are equivalent and the ingredient profile is cleaner.

Best for: Plantar fasciitis, Achilles tendonitis, arthritis pain, post-exercise soreness, bunion pain. Not ideal for: Open wounds or broken skin (apply only to intact skin).

Running and Sports Performance Insoles

Performance insoles designed for running and sports qualify for FSA/HSA when used to treat or prevent conditions like plantar fasciitis, shin splints, or metatarsalgia. The distinction matters: a comfort insole purchased solely for convenience may not qualify, but a therapeutic performance insole recommended by your podiatrist for a diagnosed condition absolutely does. Athletes are particularly good candidates for FSA/HSA insole purchases because repetitive impact accelerates foot conditions.

CURREX RunPro — Best Running Insole ($50–$60)

The insole I put in my own running shoes. CURREX RunPro features dynamic flex zones that adapt to your gait in real time — the support shifts as your foot moves from heel strike through toe-off. Available in low, medium, and high arch profiles so you get the right support for your foot type. The PORON cushioning absorbs 20% more impact energy than standard EVA foam, which directly reduces stress on the plantar fascia and metatarsal heads during high-impact activities.

Best for: Runners with plantar fasciitis, shin splints, metatarsalgia, athletes needing impact absorption. Not ideal for: Casual walking shoes (overkill — PowerStep Pinnacle is better value for daily wear).

CURREX WorkPro — Best for Standing Occupations ($50–$60)

CURREX WorkPro provides the same dynamic support technology in a profile designed for work boots and occupational footwear. If you spend 8+ hours on your feet in healthcare, construction, manufacturing, or retail, WorkPro reduces fatigue and prevents the end-of-shift foot pain that leads to chronic conditions. The reinforced heel cup stabilizes the calcaneus and reduces the lateral motion that causes ankle sprains on uneven surfaces.

Best for: Healthcare workers, construction, warehouse, retail — any standing occupation. Not ideal for: Dress shoes (too thick for most dress footwear).

Women’s Therapeutic Foot Cushions

Women’s dress shoes, heels, and flats create unique biomechanical challenges that standard insoles cannot address. The narrow toe boxes compress the metatarsal heads, elevated heels shorten the Achilles tendon, and minimal cushioning accelerates fat pad atrophy. Targeted foot cushions designed specifically for women’s footwear are FSA/HSA eligible when used for diagnosed metatarsalgia, Morton’s neuroma, or forefoot pain.

Foot Petals Tip Toes — Best Ball-of-Foot Cushion ($10–$15)

Designed specifically for women’s shoes where a full insole will not fit. Foot Petals Tip Toes provide discreet ball-of-foot cushioning that absorbs pressure on the metatarsal heads without taking up extra space in already-tight shoes. The medical-grade gel redistributes weight across the forefoot, reducing point pressure on the 2nd and 3rd metatarsals where Morton’s neuroma and capsulitis most commonly develop. In our clinic, we recommend these for patients who need relief but cannot switch to athletic shoes for their profession.

Best for: Metatarsalgia in dress shoes, Morton’s neuroma, forefoot pain from heels. Not ideal for: Plantar fasciitis (does not provide arch support — pair with PowerStep in other shoes).

Foot Petals Heavenly Heelz — Best Heel Grip ($10–$15)

Foot Petals Heavenly Heelz prevents heel slippage in pumps and flats while cushioning the posterior calcaneus. Heel slippage causes blisters, Achilles irritation, and compensatory gait changes that lead to knee and hip problems. The adhesive-backed cushion stays in place and reduces friction at the heel counter, which is particularly beneficial for patients with Haglund’s deformity or retrocalcaneal bursitis who cannot tolerate rigid shoe backs.

Best for: Heel slippage, Haglund’s deformity, retrocalcaneal bursitis, blister prevention. Not ideal for: Athletic shoes (not designed for high-impact use).

Barefoot Shoe Inserts

The barefoot shoe trend has brought a new category of patients to our clinic — people experiencing foot pain from minimal shoes that offer zero support. If you wear barefoot-style shoes and have any foot condition, a thin therapeutic insert can bridge the gap between the barefoot experience and the support your feet need.

FLAT SOCKS — Best Barefoot Insert ($15–$20)

The barefoot feel without the sweat. FLAT SOCKS slide into any shoe as a no-sock alternative with antimicrobial and moisture-wicking properties. For patients transitioning to barefoot shoes, FLAT SOCKS provide a hygienic barrier that prevents bacterial and fungal growth without the bulk of traditional insoles. They are FSA/HSA eligible as a therapeutic hygiene product for patients with hyperhidrosis, diabetic foot care needs, or recurrent athlete’s foot.

Best for: Barefoot shoe wearers, hyperhidrosis, fungal prevention, minimalist footwear. Not ideal for: Patients needing arch support (no structural correction — pair with orthotics in other shoes).

Night Splints and Braces

Night splints and therapeutic braces are some of the most clearly FSA/HSA eligible products because they are explicitly medical devices. The Strassburg Sock for plantar fasciitis, ASO lace-up ankle braces for chronic instability, and walking boots for stress fractures all qualify without question. These are the products your benefits administrator will never push back on because their medical purpose is self-evident.

In our clinic, we prescribe night splints for plantar fasciitis that has not responded to 4–6 weeks of stretching and insoles. The Strassburg Sock maintains the plantar fascia in a gentle stretch overnight, which prevents the morning heel pain that occurs when the fascia contracts during sleep. ASO lace-up braces provide the gold standard external support for patients with chronic ankle instability who are not yet candidates for surgical reconstruction.

Foot Care Tools and Devices

Foot care tools including callus removers, nail care kits, foot soaks with therapeutic ingredients, and EMS foot massagers qualify for FSA/HSA when used for diagnosed conditions. Diabetic patients in particular should invest FSA/HSA funds in proper foot care tools because daily foot maintenance prevents the ulcers and infections that lead to amputations. An electric callus remover is safer than razor blades, and a proper nail nipper prevents ingrown toenails that require surgical intervention.

Epsom salt foot soaks qualify when used therapeutically for conditions like gout flares, post-surgical swelling, and muscle cramping. The magnesium sulfate is absorbed transdermally and provides genuine muscle relaxation and anti-inflammatory effects. Pair with Doctor Hoy’s Natural Pain Relief Gel after soaking for enhanced absorption while skin is still warm and pores are open.

How to Use Your FSA/HSA for Foot Products

Using FSA/HSA funds for foot products is straightforward when you follow the right steps. First, purchase the eligible product using your FSA/HSA debit card — most major retailers accept these cards directly, including Amazon. If you pay out of pocket, save your receipt and submit a reimbursement claim through your benefits portal. For products that could be questioned, request a letter of medical necessity from your podiatrist before purchasing. In our clinic, we provide these letters at no additional charge for our patients.

Keep receipts for all FSA/HSA purchases for at least 3 years in case of an audit. The IRS can request documentation proving that purchases were for qualified medical expenses. A simple folder on your phone with photos of receipts is sufficient documentation for most administrators.

FSA vs HSA: Key Differences for Foot Care

The critical difference between FSA and HSA accounts determines your buying strategy. FSA funds expire at year-end (or March 15 with a grace period, depending on your employer) — use them or lose them. This is why December becomes a rush. HSA funds roll over indefinitely and can even be invested, so there is no urgency to spend by a deadline. If you have an HSA, you can strategically purchase foot care products throughout the year as needed rather than scrambling at year-end.

Both account types share the same eligible expenses for foot care. The contribution limits differ: FSA maxes at $3,200 for 2026, while HSA allows $4,300 for individuals and $8,550 for families. If you have ongoing foot conditions requiring orthotics, compression socks, and therapeutic products, maximizing your pre-tax contributions specifically for these expenses saves 25–35% compared to paying after-tax dollars.

In-Office Treatment at Balance Foot & Ankle

FSA and HSA funds also cover in-office podiatric treatments — not just products. If OTC products are not resolving your pain, your tax-free dollars can go toward custom 3D orthotics, shockwave therapy for plantar fasciitis, laser treatment for toenail fungus, and comprehensive foot evaluations. These in-office treatments often provide faster and more complete resolution than products alone.

Frequently Asked Questions

Are insoles FSA/HSA eligible?

Yes. Therapeutic insoles like PowerStep Pinnacle and CURREX RunPro are FSA/HSA eligible when used for a diagnosed foot condition such as plantar fasciitis, flat feet, or metatarsalgia. Since the CARES Act of 2020, OTC medical products no longer require a prescription. Having a letter of medical necessity from your podiatrist strengthens any claim.

Can I buy compression socks with FSA money?

Yes. Medical compression socks (15–20 mmHg and 20–30 mmHg) are FSA/HSA eligible when used for diagnosed conditions including venous insufficiency, post-surgical swelling, lymphedema, and occupational edema. DASS medical compression socks with graduated compression qualify as a medical device.

Do FSA funds expire at the end of the year?

Most FSA plans follow a use-it-or-lose-it rule — unused funds expire at the end of the plan year. Some employers offer a grace period (up to 2.5 months) or a carryover option (up to $640 for 2026). Check your specific plan details. HSA funds, by contrast, roll over indefinitely and never expire.

Are custom orthotics covered by FSA/HSA?

Custom orthotics are one of the most clearly eligible FSA/HSA expenses. They are prescription medical devices made from 3D scans of your feet, and they treat diagnosed conditions. At $400–$600 per pair lasting 3–5 years, they are also the highest-value foot purchase you can make with pre-tax dollars. Medicare Part B also covers custom orthotics for qualifying conditions.

Does insurance cover plantar fasciitis treatment?

Most PPO plans cover plantar fasciitis evaluation and treatment when medically indicated. Medicare Part B covers custom orthotics. Balance Foot & Ankle accepts BCBS and most Michigan insurers. FSA/HSA funds can cover the remaining out-of-pocket costs. Call (810) 206-1402 to verify your coverage.

The Bottom Line

Your FSA/HSA funds are tax-free dollars designated for your health — and your feet carry you through every day of your life. Invest in products that provide genuine therapeutic benefit: PowerStep insoles for arch support, CURREX for athletic performance, Doctor Hoy’s for pain relief, DASS compression for circulation, and custom orthotics for structural correction. Do not let your FSA dollars expire on products that sit in a drawer. If your foot pain has not improved with OTC products after 6 weeks, use your remaining balance for a podiatrist evaluation instead — that is the highest-value use of your healthcare dollars.
