I usually wear a 10 1/2 but ordered an 11 because no half sizes. I ended up sending back and got 12s.The length on the 11 was about like a 10 1/2. But the stem that goes between your toes is further back. So my heal hung off the back.With the 12 heal was good but there is about an inch of sandal in front of toes.Might end up being a tripping hazard.
