The SmartWool PhD Ski Light Sock gives you all day comfort and performance fit. WOW Technology™ adds an additional layer of 100% SmartWool Duroyarn in the High Impact Zones to give the new PhD sock up to 30% more durability. Also a heel-top band keeps the sock from snagging even a millimeter, and an elastic band over the top of the upper instep prevents bunching.
Features:
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.
Strategically placed mesh ventilation zones provide ventilation for temperature and moisture management.
Flat knit durable toe seam seam for high burst strength.
