An insole can't fix plantar fasciitis on its own — but the wrong footwear will definitely make it worse, and the right insole is often the difference between a 3-month recovery and a 12-month one.
What you're looking for is arch support that controls the mechanics causing your fascia to stay inflamed, not just cushioning that makes each step feel softer. These are different things. Here are the five best insoles for plantar fasciitis in 2026, ranked by clinical effectiveness and podiatrist recommendation frequency.
What to look for
The 5 best options in 2026
The benchmark OTC orthotic. Superfeet Green has been the podiatrist default recommendation for 40+ years — the stabilizer cap and heel cup design is biomechanically sound and corrects the overpronation that causes most plantar fasciitis. APMA accepted.
- Widest deepest heel cup of any OTC insole
- Semi-rigid stabilizer cap corrects overpronation
- APMA seal of acceptance
- Lasts 12 months or 500 miles
- Takes 1-2 weeks to break in
- High volume — doesn't fit thin or tight shoes
#1 podiatrist-recommended OTC orthotic by prescription volume. The dual-layer cushioning handles high-impact activity better than Superfeet while providing the semi-rigid control that plantar fasciitis requires.
- #1 recommended by podiatrists by volume
- Better cushioning for high-impact activity
- Anti-microbial top cover
- Works in most shoe types
- Slightly less arch height than Superfeet
- Needs replacing every 6 months with heavy use
Not as biomechanically sophisticated as Superfeet or Powerstep, but for $18 the targeted gel heel cushion and moderate arch support provide meaningful relief. Best for mild cases or as a temporary solution while waiting for custom orthotics.
- Cheapest effective option
- Widely available in drugstores
- Immediate out-of-box comfort
- Good for mild cases
- Less structural support than premium options
- Softer foam compresses faster
- Not for severe overpronation
Specifically designed for low arches and flat feet. The orthaheel technology corrects excessive pronation at the subtalar joint — the root cause of plantar fasciitis in flat-footed patients. Works in casual and dress shoes where Superfeet won't fit.
- Designed specifically for flat feet
- APMA accepted
- Works in casual and dress shoes
- Lower profile than Superfeet
- Less aggressive heel cup
- Not ideal for high arches
Same proven Superfeet biomechanics in a wider heel cup and broader arch for 3E-6E wide feet. Wide-footed patients often give up on insoles because standard sizes don't fit — this solves that problem completely.
- Proper fit for wide feet
- Same structural support as standard Green
- Available in full size range
- More expensive than standard Green
- Only for genuinely wide feet
The bottom line
Superfeet Green is the right call for most plantar fasciitis patients — the heel cup and arch profile match what podiatrists prescribe in custom orthotics at a fraction of the price. If you pronate heavily during running, Powerstep Pinnacle is the better option. Flat feet need Vionic.
Whichever insole you choose, give it two full weeks before judging. The structural correction needs to accumulate across thousands of steps before you notice the difference in morning pain.
