I loved these from the moment I put them on my size 10 flat feet with bunions. I am a 39 y/o runner and have the hardest time finding shoes that fit in width, length, and with arch support. Believe it or not these do support the arch well with the foot shaped Vibram sole. They fit like a sock. No pressure on my bunions and no slipping at the heel. I was apprehensive at first about minimalist shoes because I'm use to running in shoes for overpronators with cushion and stability. I am way over all that bulk. These work great and I feel my lower leg deep muscles firing and strengthing which doesn't happen when the foot is overly splinted with the traditional running shoe. Try these you will love them.
