I generally wear a 10.5, and bought these in an 11 as Pumas seem to generally run a little tight for me. Initially I thought they were too narrow in the sole and too tight across top of my foot. After deciding to give them a couple days of break in, I absolutely love them. They are my most comfortable shoes. I work in real estate and generally dress casual, and love these with jeans and a polo. They also are very quick on and off, which is great going from house to house. I couldn't be happier.
