Ordered these in the black/yellow and so far pleased with them overall. The strap fits snugly and the shape of the shoe molds to the foot to make them almost slip-free when walking (which actually takes a little getting used to if you normally wear looser style flip-flops). The best part is the wonderful massaging action in the cobbled surface of the footbed. I wanted something that would be comfortable for extended walking and still look stylish, and this one fits the bill. I like them well enough that I plan to order another pair in a different color. If you are a half size, I'd advise ordering the next smaller size. I'm a 7 1/2 and the 7 fit perfectly, the exact length of my foot.
