Really surprised by the comfort of this shoe. After wearing them for three days, they fit my foot very well. The shoes are very thin and it feels like I'm wearing socks and not real shoes as the size is minimal. It's comfortable to walk in and makes a great show for rock climbing, yoga, or running. I'll do an additional review in a month or so. But if these hold up I will definitely buy other pairs. While I will say this, due to the lack of a sizing chart on the listing, I was unsure of what size to take or what would fit me best. So I ordered the small and the medium and sent the medium one back when I found it was too big. Revain has a friendly returns policy, so it wasn't a big deal. Update: They didn't even last a month, the cross strap has already scuffed at the hem and is now just loose. Update 2: I bought another pair because I like the comfort. I like the shoes, but it is clear that they are not designed for long-term use. Shoes break in in about the first month, or sooner if you wear them regularly.
