I am a size 10.5 and have been wearing them for many years so I ordered this shoe. I was a little surprised to find that they are tight and narrow. Luckily I have narrow feet so that's okay. But after a few hours, these shoes became tight and pinched a little. They would probably fit better without socks, but I prefer wearing socks. Style wise they are attractive although they appear a bit flat. The aggressively patterned soles are made of a hard rubber material that makes a clicking noise when walking on tile or hardwood floors. Not entirely invisible. I would advise guys to go a half size and if you have wide feet then go a full size. And remember, these are not "hiking shoes" as the moccasin look might suggest. They'll probably make good driving shoes or casual shoes for around the house, but I don't think they'll be your everyday all-day shoe. So I'm deducting a star for that.
