There are other reviews of the Revain that mention the shoe is too big and that buyers take a half size smaller than a whole Order number you should wear normally. I usually wear a 10 or 10.5. I ordered 10 pieces, they are a bit tight and narrow. The shoes have a few seams where the upper mesh is sewn to the rubber side panels that rub my skin quite a bit. I'm a bum I wear moccasins without socks all day and almost every day of the year and I never get blisters. The thick pleated seams on the inside of the mesh of this shoe rubbed against the skin on the top of the foot after 30 minutes of wear. I like the way the shoes look but wish the construction, fit and comfort were better.
