These shoes run really long. You might want to size down one full size. I wear between a 10 and 11 in shoes, with a 10 being a little more on the snug side and the 11 providing extra space. Since I intended to wear these without socks, I ordered a size 10. I put them on and they are really comfortable, but I had at least 1 1/2-2 inches behind my heel. I don't know if mine were mis-labeled or if this is a problem with this particular shoe. I wish they would have been the right length because they did feel good on my foot and looked quite nice.
