I wear a 10-10 1/2 half. After reading reviews I decided to buy the 11 to make sure my toes don't rub. They are roomy and as I walk all day on rubber anti fatigue mats they seem to have stretched a small bit. I've worn them for two weeks everyday. I rarely sit down  and my feet are not tired nor do I have blisters. The laces keep a nice snug fit around the foot as well. Nice shoe but if I could have would have bought the 10 1/2.
UPDATE.... Ive' worn this shoe everyday for a month and a half and an sad to say that they have broken down. I had to put inserts in to get any kind of comfort. Sorry to say you do get what you pay for
