The answer to the question I always want to ask is YES, they fit great. I have wide feet and always wear D sizes. The sizing for these shoes is marked "M" for a medium size, which Florsheim says includes sizes like B, C, and D, all in the same category (M). I was very skeptical; I took a risk and it worked. The shoes are perfect, although the width (new out of the box) is a little tight in thin ankle socks. A NOTICE. These shoes stretch with use and take the shape of the foot, making Florsheim flip flops the most comfortable shoes in my wardrobe. I like the bottom of the shoe. The material used won't slip off a wet brake pedal, and the heel won't get in the way of a sharp action. But for someone who has shrunk almost an inch with age I'm missing a heel (solely ego), lolShoes arrived ahead of the expected delivery time in perfect condition - immaculate soft leather shoes on the outside and comfortable soft leather on the inside.
