The PhD® Ski Light keeps your feet warm and dry without sacrificing boot performance. We placed cushioning where skiers need it most: on the shin for protection against the boot and on the bottom of the foot for warmth and impact protection. Made with our 4 DegreeTM elite fit system for a sock that never bunches, slips, or binds. And our patented ReliaWoolTM technology provides superior durability to make sure your socks are ready to go, run after run.
