Most comfortable socks ever because they are combed cotton and a thick terry material You will not get blisters because the socks do not shift around and stay in place, in part because they are thick and will stay in place filling any play. Length is perfect, comes nicely up the calf. Love these, best socks on the market at the moment. Nice and simple and clean looking design. Plush and thick. Combed cotton is the best, doesn't feel like plastic like most other socks, so glad to see socks like this. The thickness is a good thing as it keeps your foot in place in your shoe and provides cushion. Socks with complicated meshes etc are just gimmick, your feet are going to get hot no matter what if they are in shoes. The quality is high and the socks stay in place and keep their shape. The only knock is these are over priced.
