Flat feet (pes planus) affects about 30% of the population, and most people with it have no pain at all. The problem starts when flat arches cause overpronation — the inward rolling of the foot that strains everything from the fascia to the knees to the lower back.
The right orthotic corrects that inward roll mechanically with every step. Here are the five best orthotics for flat feet in 2026, from OTC options that work surprisingly well to the custom route when you need it.
The #1 podiatrist-recommended OTC orthotic by prescription volume — and the reason is the polypropylene shell that provides genuine motion control without the bulk of a custom device. For mild to moderate flat foot with overpronation, this handles 70-80% of what a custom orthotic does.

Superfeet Blue is specifically designed for medium arches and flat feet — different from the high-arch Green. Lower profile with a moderate arch height that fits better in lower-volume shoes and provides the support without overcorrecting.
Running-specific orthotic designed for runners with flat feet who need pronation control during high-impact activity. Lighter and more flexible than general-purpose orthotics while still providing the arch support needed.

Wide-footed patients with flat feet often give up on orthotics because standard sizes don't fit. The Superfeet WideGreen provides the same stabilizer cap and deep heel cup in a wider heel and broader arch that accommodates 3E-6E wide feet properly.
For moderate to severe flat foot deformity causing significant pain or gait problems, custom orthotics cast from your foot provide correction that no OTC product can match. Often covered by insurance with a podiatry prescription. The long-term investment that OTC products are bridging toward.
Powerstep Pinnacle is the right starting point for most people with flat feet — it provides genuine motion control at an accessible price. If you have wide feet, go Superfeet WideGreen. If OTC orthotics haven't resolved your symptoms after 6-8 weeks, the custom orthotic route through a podiatrist is worth the investment.
Flat feet without pain are not a problem that needs fixing. If your flat feet aren't causing symptoms, no intervention is necessary.
A podiatrist can fit you for exactly the right product combination for your foot type.
