When I had plantar fasciitis I found that the best insole by far were these ones as they give your feet really rigid support and absorb shock which really does help ease pressure off your arches whilst your feet heal up. If I was you I would buy those or at least buy some that are rigid around the arch to properly support the fascia of your foot but flexible around the heel so that your Achilles heel can flex and stretch out fully whilst you walk this is because a tight Achilles heel can cause the plantar fascia to also become tight which can cause plantar fasciitis. Hope this helps.
