Smartwool equipped its Phd Run Graduated Compression Ultralight Pattern Sock with just about everything you need for a comfortable sprint. Graduated compression socks promote oxygenated blood flow to your lower legs, reducing lactic acid build up. Overall, this reduces swelling and allows your muscles to recover more quickly so you can get back out there and do it all over again. These socks have a compression rating of 20-30mmHg (medical-grade compression is 30+). Along with the compression, a 4 Degree Elite fit system keeps the sock from losing its shape over time. Made mostly out of an ultralight merino wool, this sock assists with temperature regulation and odor resistance. ReliaWool technology places more wool in high-impact areas for longevity and extra comfort, and Smartwool also added mesh ventilation zones for airflow and a low-profile toe seam to keep chafing at a minimum.
