Smartwool Performance Ski Ultra Light Sock reviews and deals for sale

The PhD Ski Ultra Light Sock gives you maximum warmth without the bulk, and its Indestructawool yarns promise to wrap around your feet with a durability that seems impossible considering their soft, stretchy feel. The breathable mesh venting and supportive 4 Degree elite fit should all but erase that horrible wet-cotton feeling you've managed to repress for all of these years.
