The SmartWool PhD Graduated Compression Ultra Light Sock combines all of SmartWool's most advanced technology to create a sock that insulates, dries, cushions, breathes, and even applies compression from the toes to the calf to aid circulation and speed recovery.
- Graduated compression keeps feet from swelling as you exercise, which improves performance and speeds recovery
- Wool Over Wool knit pattern at impact zones creates extra cushioning and shock-absorption
- Merino manages moisture and insulates even when wet so you don't get a case of cold feet
- Strategically placed mesh zones allow perspiration to evaporate away
- Ultra Light thickness means you won't even notice the sock under your boots
