Excellent purchase. The size was absolutely correct; they fit my feet perfectly without needing to order a different size. They're also incredibly comfortable from the first wear, ideal for everyday use as well as long walks. The quality feels very good, and the design is exactly as pictured. I would definitely buy them again.

Size 11 is short.

Size: 11, Color: (110) Summit White/Summit White/Khaki Base

Am in process of returning them. The sole was very comfortable, but the size 11 was short. Arch support was good and appearance was fine. Disappointed that they are short.
