Hi, I had been buying/trying various insoles to help my "newly" developed plantar fasciitis last fall. Once I started wearing YOUR insoles, my heels hurt less and less. I wear them in my work shoes (I am on my feet 7 hours a shift). I have them in my athletic shoes for my TRX classes. I just started putting them in my cycle shoes for my indoor Real Ryder classes as I do not want to injure my hip joint which had been bothering me (probably from NOT enough support in the shoe). I will always buy Protalus insoles. I wasted enough money on all the other less expensive brands!
