I usually wear a size 10 or 10.5, but a size 10 is too small for me. Even 10.5 is about to get too tight. These shoes are stiff and the tongue has a hard shell that puts pressure on my ankle. I sent them back due to the size but I think it would take a while for them to break in. I also noticed that the patent leather tongue had creases from the laces after only wearing them around the house for a few hours to test them out.
