Teva's size 11 women's flip flops were too small so I decided to try men's flip flops. When I get men's shoes I usually order 9, but after reading the reviews I decided to order 10. The men's 10 fit perfectly and are very comfortable.
Pros
Favorite sandals in summer and winter. He doesn't wear others
Cons
The tape can rub against the skin and cause blisters.
