Im a solid 10.5, regular width, in basically every shoe. The size 11 in these slides gives me practically no extra room in length, and the chunky EVA strap is way too tight on the tops of my feet. These do not stretch over time. Definitely size up to next whole size for comfort. If youre between sizes like I am, go up a full size and a half. Had to re-order in size 12.
