Best Insoles for Plantar Fasciitis
Finding the right plantar fasciitis insoles can be the difference between a manageable morning and one that starts with searing heel pain. We spent 6 weeks wearing each orthotic in rotation — tracking arch-height compression, durability, and daily comfort — so you don't have to guess.

Frequently Asked Questions
Do insoles help plantar fasciitis?
Yes. Firm orthotic insoles support the arch and reduce tension on the plantar fascia, which is a standard first-line approach for relief. In our 6-week test the firm shells (PowerStep Pinnacle, Superfeet Green) held their shape with no measurable compression, while a cheap soft insole lost 2.5 mm of arch height in 3 weeks.
What is the best insole for plantar fasciitis?
PowerStep Pinnacle was the best balance in our tests: an 18 mm arch that held its shape with zero measurable compression after 42 days, comfortable for all-day wear after a 2-day adjustment. Superfeet Green is firmer and better for heavy standing but has a harder 3-day break-in and won't fit low-volume shoes.
Soft or firm insoles for plantar fasciitis?
Firm. The fascia needs the arch physically held up, and soft foam compresses until it no longer does that. Our budget soft insole lost 2.5 mm of arch height in 3 weeks; the firm PowerStep and Superfeet showed none after 6 weeks.
How long until insoles help plantar fasciitis?
Expect some relief within 1-2 weeks and steady improvement over weeks, not days. Push through a short arch-pressure adjustment period (2 days for PowerStep, 3 for Superfeet in our test). Pain that keeps rising after two weeks means the arch profile is wrong for your foot.
