After doing research on the best shoes for plantar fasciitis, I decided to give these a try. These are not for me. It says you can adjust the firmness, but I found they are too firm even without the removable bars in the soles. I work walking on concrete and these soles are just too hard for my feet. I love the look of the shoes and the fact that you can just slip them on without tying. But I would not recommend these for someone with plantar fasciitis.
