Smartwool PhD Run Light Elite Micro Socks

The PhD Run Light Elite Micro Socks are Smartwool's best-fitting, most advanced running socks yet. Featuring lightweight elite cushioning in the ball and heel of the foot for ultimate shock absorption with minimal in-shoe volume, strategically placed ventilation zones and a virtually seamless toe deliver ultimate comfort.

A 200 needle construction provides the highest knit density whilst maintaining an ultra light weight. Maximum impact protection is provided by targeted cushioning on the ball and heel of the foot. The cushioning zones are designed and located specifically to suit runners, ensuring that their feet stay irritation free, and therefore enabling them to focus on the run ahead. The men's specific mesh ventilation zones work in concert with the maximum impact protection system to provide additional breathability and moisture management, preventing any blistering or irritation from occurring. Patented ReliaWool technology is added to high impact areas to provide super durability in high-wear areas. A four-degree elite fit system uses two elastics for greater stretch and recovery to keep the sock in place; this allows the sock to move naturally with the foot for unrestricted movements.
