Smartwool Hike Classic Edition Light Cushion Crew Socks Alpine Blue Small. The Classic Hike remains mostly unchanged and certainly unmatched in comfort. But today its getting upgraded. And that upgrade starts with recycled nylon-creating a more sustainable (but just as comfortable) sock.

This is a cozy capable classic that is never going out of style.
