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.
