Sock Geek Says:

Updated version of this popular high performance running sock.  Strategically mapped footstrike cushioning with new clearly defined pattern is even more closely aligned to the pressure patterns of your feet.  New split toe design adds extra cushioning under the big toe to improve comfort as you land, transition, and accelerate through the gait cycle.  High performance Dri-FIT microfiber polyester is highly breathable and quick drying to ensure blister free comfort.  Anatomical left/right fit enhances comfort and performance.
