SmartWool PhD Ski Ultra Light Sock
Where to Buy
Here's what other sites are saying:
Smartwool's PhD Ski Ultra Light Sock was designed after the classic Ski Ultra Light, except with a 4-Degree Elite fit system and ReliaWool Technology to create Smartwool's most comfortable and durable sock yet.
Unless you've completely blocked it from your memory, you might remember your very first time on skis and the way you felt when you withdrew your pasty, clammy foot from a wet, frozen bunched-up cotton sock. The Smartwool PhD Ski Ultra Light Sock gives you maximum warmth without the bulk and without that horrible clammy wet-cotton feeling you've hopefully managed to erase from your mind.
