I bought these after wearing another Cole Haan Air sandal that is very comfortable. The only issue on this new pair is the top of the left sandal rubbed the top of my foot (perhaps the arch is higher on this foot). This did not happen with the previous sandal. I think it is due to the buckle and how it rests in the center of the shoe. I added a little padding in the center of the strap and I was all set.
