Smartwool Mens PhD Running Graduated Compression Ultra Light Socks
These are the coolest running socks you'll ever wear. SmartWool started with the natural benefits of merino wool (moisture-wicking and temperature regulation) and added the benefit of graduated compression. Compression socks improve circulation in your feet which improves your recovery and flushes lactic acid faster.
New 4 Degree Elite Fit System uses two elastics for greater stretch and recovery to keep the sock in place
Patent pending ReliaWool Technology in high impact areas provides the longer lasting protection to keep feet comfortable
