Quick Answer
Flat feet (pes planus) means the arch has collapsed, causing the ankle to roll inward. When flat feet cause plantar fasciitis, shin splints, or knee pain, custom orthotics combined with supportive footwear resolve most cases. Asymptomatic flat feet usually need no treatment.

Dr. Tom’s Top 3 Picks for Flat Feet in Adults
Adult flat feet — whether lifelong flexible or newly acquired (posterior tibial tendon dysfunction) — need three things: a shoe with a firm medial post, an insole with real arch support, and Medicare-grade stability for longer-term use. These are the three I recommend most often to flat-foot patients in our clinics.

Best Insole Add-On
No products found.
Podiatrist Pros
- Firm-but-flexible EVA arch with a deep heel cradle — matches the neutral-foot biomechanics most patients have
- Semi-rigid shell supports the medial arch without the painful break-in period that plastic-shell insoles (PowerStep Pinnacle) cause
- Fits most athletic, work, and casual shoes with a removable factory insole — doesn’t require volume shoes
- Antimicrobial top cover lasts ~12 months under daily wear; most patients re-order before it fails
Honest Cons
- Too firm for patients with fat-pad atrophy or advanced hallux rigidus — they need the softer Pulse version
- Full-length; you must remove the shoe’s factory insole. Won’t work in minimalist or low-volume dress shoes
Dr. Tom’s Take: My default orthotic recommendation for plantar fasciitis, mild-to-moderate flat feet, and Achilles tendonitis. Better value than PowerStep Pinnacle for 90% of patients, which is why I swapped it into our clinic kits three years ago.
Best Stability Shoe
- THIS MEN’S SHOE IS FOR: The Adrenaline GTS 25 is perfect for runners and walkers seeking reliable support and a smooth ride. Featuring holistic GuideRails for Go-To Support and soft, dynamic premium nitrogen-infused DNA LOFT v3 cushioning, it delivers distraction-free comfort mile after mile. This Brooks Adrenaline GTS 25 is a certified PDAC A5500 Diabetic shoe and has been granted the APMA Seal of Acceptance. Predecessor: Adrenaline GTS 24.
- GUIDERAILS HOLISTIC SUPPORT SYSTEM: Our innovative technology - known as “GTS” for “Go-To Support” - supports your body in its natural motion path while keeping excess movement in check.
- SOFT & DYNAMIC CUSHIONING: Even more premium nitrogen-infused DNA Loft v3 cushioning delivers lightweight softness, and feel-good comfort mile after mile.
- TRUSTED FIT: The breathable engineered mesh upper and flat-knit collar offer a secure, comfortable fit, providing both structure and flexibility to accommodate natural movement during active use.
- SMOOTH TRANSITIONS: The specially designed outsole and midsole work together to promote seamless transitions, ensuring comfort and support for every step, so you can stay active longer.
Podiatrist Pros
- GuideRails system prevents excess rearfoot rotation without a rigid medial post — stability without the stiffness
- DNA LOFT v2 midsole strikes a better balance between cushion and response than the Ghost or Glycerin
- Neutral runners can wear it without feeling over-corrected; overpronators get the guidance they need
- Consistent last from year to year — if you liked the GTS 22, you’ll like the GTS 25
Honest Cons
- Heavy side of the stability category (~10oz men’s) — not a race-day shoe
- Runs slightly narrow in the midfoot; go 2E width if your forefoot spreads
Dr. Tom’s Take: My single most-recommended running shoe across the practice. If you’re new to running, have mild overpronation, or returning from plantar fasciitis, start here.
Best for Diabetic Feet
- Leather or Natural Cork Upper
- Microfiber Wrapped EVA Footbed
- Durable Rubber Outsole
- APMA Seal of Acceptance
- Vionic offers innovative biomechanical technology concealed in every style, so you can enjoy all life’s occasions with confidence and comfort – all day, every day.
Podiatrist Pros
- Medicare-approved motion-control walking shoe — one of the few Walking shoes billed through orthotic coverage
- ROLLBAR technology controls rearfoot motion in flat-footed patients
- Removable footbed accommodates custom orthotics or aftermarket insoles
- Extended widths (up to 6E) — fits swollen or diabetic feet that won’t go into normal shoes
Honest Cons
- Orthopedic aesthetic — this is a function shoe, not a style shoe
- Stiffer than the 990 and less comfortable for patients who don’t actually need motion control
Dr. Tom’s Take: The 928v3 is what I recommend for diabetic patients, patients with lymphedema, and severe overpronators who need a truly medical-grade walking shoe. If you don’t fit that profile, the 990v6 is more comfortable.

Podiatrist Recommended Orthotics 2026: Dr. Tom’s Top 10 Insoles & Arch Supports
A podiatrist’s complete clinical guide to the best insoles — custom orthotics, OTC picks, and what actually works for plantar fasciitis, flat feet, neuropathy & more.
Read the Full Guide →Flat Feet in Adults: Do You Actually Need Treatment?
Flexible vs rigid, symptomatic vs painless — how we decide whether flat feet need orthotics, surgery, or just monitoring.
About 25% of adults have flat feet — most are painless and need no treatment. Intervention is for symptomatic cases: aching arches, posterior tibial tendon pain, rapid wear patterns on shoes, or painful heel-to-toe transition. Treatment ladder: (1) supportive shoes with firm heel counter, (2) OTC orthotics (Powerstep Pinnacle), (3) custom orthotics for severe cases, (4) PTT-strengthening exercises, (5) flatfoot reconstruction surgery for progressive collapse that fails 6+ months of conservative care. Never treat asymptomatic flat feet.
Every product in this guide was selected by a board-certified podiatrist based on clinical outcomes in real patients — not based on affiliate commission rates. We've ranked them based on biomechanical design, durability, patient compliance, and cost-to-benefit ratio. All picks are personally recommended in our Michigan clinics every week.
PowerStep Pinnacle (Max Support)
Gold-standard flat foot orthotic
See full description under HIKING_INSOLES — PowerStep Pinnacle is the most-prescribed insole for adult flexible flatfoot for the same reasons it works for hiking: rigid stabilizer cap controls rearfoot pronation, medium-high arch lifts the collapsed medial longitudinal arch, and the deep heel cup maintains calcaneal alignment. For PTTD stage 1 (reducible flatfoot with medial pain), PowerStep Pinnacle plus Alfredson-style calf strengthening prevents progression to stage 2 (rigid). For rigid deformity, you need a custom orthotic — no OTC product will help.
- Adult flexible flatfoot
- Posterior tibial tendon dysfunction (PTTD) stage 1
- Overpronation
- Rigid deformity
- Pediatric flatfoot
- ✔ Controls overpronation
- ✔ Prevents PTTD progression
- ✔ 25-year clinical evidence base
- ✔ Cut-to-fit
- ✖ Won’t help rigid flatfoot
- ✖ 2-3 day break-in
Protalus M-Series Insoles
Aligns the subtalar joint — newer engineering
Protalus M-Series uses a deeper heel cup (20mm vs. PowerStep Pinnacle’s 15mm) and a neutral-position subtalar joint wedge designed to bring the calcaneus into more neutral alignment. Newer technology than PowerStep Pinnacle (launched 2015); the biomechanical theory is that subtalar alignment reduces secondary knee and hip compensation, not just arch collapse. Patients with flat feet plus anterior knee pain or ITB syndrome often find Protalus more effective than PowerStep Pinnacle. Higher price, longer life (12-18 months vs. PowerStep Pinnacle’s 9-12 months).
- PTTD stage 1
- Flat foot with knee pain
- Alignment-focused patients
- Very narrow feet
- ✔ 20mm heel cup — deepest in class
- ✔ Addresses alignment chain
- ✔ 12-18 month lifespan
- ✔ Newer engineering
- ✖ $100+ price point
- ✖ Narrower forefoot than PowerStep Pinnacle

When to See a Podiatrist
Painful flat feet in adults can signal posterior tibial tendon dysfunction — a progressive condition that needs early intervention to avoid surgery. Balance Foot & Ankle evaluates adult flatfoot with weight-bearing imaging and custom orthotic prescriptions. Catching PTTD at stage 1-2 makes the difference between a brace and a reconstruction.

Frequently Asked Questions
Do flat feet always cause pain?
No. About 25% of adults have flat feet; most are asymptomatic and stay that way for life. Treatment is driven by symptoms (arch pain, PTT pain, rapid shoe wear), not appearance. 'Fixing' asymptomatic flat feet with orthotics is not indicated and may cause new pain.
What's the difference between flexible and rigid flat feet?
Flexible: the arch appears when you stand on your toes or sit with feet off the ground; the bones are normal but ligaments are loose. Responds to orthotics. Rigid: arch stays flat regardless of position; often indicates bone abnormality (tarsal coalition) and may need surgical evaluation. We test this in clinic in 30 seconds.
Do I need custom orthotics or will OTC work?
Start with OTC (Powerstep Pinnacle or Pulse). If they reduce pain by 60-80% within 4 weeks, continue. If pain persists or worsens, consider custom orthotics — they're molded to your specific arch shape. Custom is warranted for: severe pain, abnormal biomechanics on gait analysis, post-surgical support, or diabetic foot deformity. ~$400-600; many insurance plans cover.
Can exercises alone fix adult flat feet?
Exercises (short-foot, heel raises, toe grips) strengthen the posterior tibial tendon and intrinsic foot muscles but rarely raise the arch in adults. They're supportive, not curative. Combine with orthotics for best outcomes. In children, exercises + orthotics can help the arch develop; in adults, the bones are set.

Differential Diagnosis: What Else Could It Be?
Several conditions share symptoms with Flat Feet (Pes Planus) and are commonly misdiagnosed in the first office visit. Considering these alternatives is part of every Balance Foot & Ankle exam:
- Posterior tibial tendon dysfunction (PTTD). Acquired adult flatfoot with single-leg heel-rise weakness.
- Tarsal coalition. Rigid flatfoot in an adolescent — bone bridge between hindfoot bones.
- Charcot foot (diabetic). Sudden warm, swollen, collapsing midfoot in a diabetic — urgent off-loading.
If your symptoms don’t fit the textbook pattern, ask your podiatrist which differentials they ruled out — that conversation often shortcuts months of trial-and-error treatment.
In Our Clinic
In our clinic, the flat-footed patient who actually needs intervention is the one whose arch is collapsing progressively in adulthood — not the person who was born flat-footed and has been running 5Ks pain-free for 20 years. We evaluate for posterior tibial tendon dysfunction (PTTD) with single-heel-rise testing, check for the “too many toes” sign from behind, and get weight-bearing X-rays. Early PTTD responds well to a custom orthotic with a medial heel skive + short course of boot immobilization. Stage 2+ PTTD is a different conversation — we discuss tendon transfers and calcaneal osteotomy candidates.
Most Common Mistake We See
The most common mistake we see is: Buying motion-control shoes without a gait assessment. Fix: get a pressure-plate analysis or wet-foot test first to confirm overpronation and arch height.
Warning Signs That Need Same-Day Care
Seek immediate evaluation at Balance Foot & Ankle if you experience any of the following:
- Rapid collapse of an arch on one foot (possible PTT rupture)
- Walking becoming impossible
- Redness or warmth along the inner arch
- Diabetes plus progressive arch collapse
