I had a very bad case of plantar fasciitis and bought a pair of Speedcross 4s and it went away. By the way, great shoes. I've also tried some of their road running shoes and they're ok, but nothing beats speedcross. That is, until now. Predict Soc is very good. I put them on and knew right away that I would love these shoes. Very light weight. So comfortable. You look great and I hear it from other people. buy you. Your legs will thank you.
