The leather used in this shoe is 1/3 thicker than the leather that Sperry used for pumps which caused the back of the shoe to wrinkle than I did went in it. I am very disappointed and will be buying from other companies from now on. Because of this, I returned this pair and another pair of Sperry shoes. This is a good time for those in Vietnam (where Sperry shoes are made) to come here and start a shoe company that makes shoes the way they were meant to be made. But they look good and true to size.
