When you look for an insole for plantar fasciitis, you look for an insole with a couple of properties:
You want an insole that has a great deal of cushioning. This will help dissipate stress and strain on the plantar fascia which can lead to a lot of the discomfort you feel do to Plantar Fasciitis
You want an insole that gives strong arch support, arch support is important because the plantar fascia needs to be supported. Why because in Plantar fasciitis your plantar fascia is tight causing the pain at its insertion. A good arch support will elevate the facia reducing the stress and strain placed on the plantar fascia.
And last you want a deep heel cup- a deep heel cup will control a great deal of the motion that can cause plantar fasciitis negating a lot of the stress placed on the plantar fascia. Below I have listed what I believe the best insoles for Plantar Fasciitis are:
Superfeet Premium Insoles– I highly recommend this insole for people who are runners or very active. The orthotic provides a great deal of arch support enough that it is probably not a great choice for people with flat feet. But if you are a runner with Plantar Fasciitis the thickness of the orthotic will help dissipate the stress that you place on the Plantar Fascia while running.
Arch Crafters Custom Fit Insoles– These insoles are nice in that they are created specifically for your foot. You place an impression in a foam box they send to you then you send it back to the company which then produces an orthotic specifically for your foot. I would recommend trying this insole after you have tried another one as these insoles are pricey, costing upwards of $100.If you have already failed other insoles this one is worth a try.
New Balance Supportive Cushioning Insole- This insole provides a deep heel cup, arch support, as well as a great deal of cushioning. This orthotic was actually created with plantar fasciitis in mind. This is a quality insole I just happen to like…
PowerStep orthotics better- The poron layer provides what I think is great cushioning for the plantar fascia. This insole also provides arch support and biomechanical control superior to that of the New Balance in my opinion.
