I actually bought a different pair of shoes from Zappos and had to return them - bought these at a bike shop. The shoes I am returning were the right size, but felt really uncomfortable around the toe box. I put these on and the difference was night and day - snug (as bike shoes should be) but comfortable. I wore them only once so far and they worked great. My toes were a little tingly by the end of class, but I was wearing socks that were too thick, and I think these will give over time as they are fabric. I wear a size 7 US and the 38 fit great.

Terrific bike to gym shoe. I wear between an 8 and 8.5, so I usually order up a half size. Very comfortable right out of the box. I can spin in these then go do an hour strength session with my personal trainer.
