I usually wear a mens size 11. The store was out of that size but had a 10 1/2 which I couldn't fit into. Had them order an 11 and it was still a tight fit, but too long. I stupidly kept them since I had already paid and waited for 2 weeks. wah wah. I should have gotten a 10 1/2 wide, if they even make that size. Bummer.
