Husband wears a 12-1/2 wide-his foot is flat-and he has Plantar Fasciitis. I shop everywhere for his shoes and sandals, these are the best I could find for his big old foot I bought them in a 13 because they did not have wide, turned out to be a perfect fit. He loves them as I do because when I watch him walk his feet look secure and normal. The heels are very supportive for his 250 pound large framed body. Plus they are stylish even when he wears white socks with them tehe tehe-(only when he is going to play golf he says he wants to be able to just slide on his golf shoes while I laugh). Anyway we really recommend these well made sandals.
