Because I have a difficult time finding socks (and shoes) that fit well, I really appreciate these socks. The weave and colorfast quality are great, they fit my size-14 foot snugly but comfortably, and the tops retain a firm fit around the calf area. The durability is fantastic, including flexibility. I have washed pairs of these sock for years, and they have held up very well in all regards. No snags, holes or fading. Quite amazing, really.
