These look great and seem to be well-made; however, their sizes are way off. I'm a U.S. 10 (M) and I read some reviews of other similar shoes (same brand and style, different colors) that warned that they run small. So I ordered a 10.5--they wouldn't even go on my feet. I returned them and hoped to get an 11.5, but as they were unavailable, I went with an 11, which fit semi-comfortably after stretching them with a shoe caddy. If you order these, go at least 1 full size up.
