I was so disappointed when I tried these shoes on. I suffer from plantar fasciitis and so many people rave about Vionic, but this was not what I was expecting. I'm immediately returning these shoes as the sole is just a thick piece of foam. They'll wear out in just a few uses. They also did not fit well and that's such an important part of good shoes for people who suffer from plantar fasciitis. I will not be getting Vionic shoes again anytime soon.
