As soon as I put these shoes on I knew I was going to be a fan of Ryka! I put these on my wishlist because of other's comments about the shoe being too wide. I wear a 6.5 and my foot is somewhat wide with a high instep. The arch support is exactly where I need it to be. I have developed Plantar Fasciitis and am hoping these will help ease that. Since I received these shoes for Christmas, I won't know for a few weeks if they help but will update this review at that time.
