12+ | Sock Geek Says: Injinji's all new Outdoor Lightweight Series is perfect for those running in trail oriented "barefoot" performance footwear or more traditional trail shoes. Also, great to wear as a liner with an over-sock for ultra distance running.
Features Injinji's patented AIS technology. Anatomical Interface System (AIS) that is engineered to separate your toes with a thin, anti-friction membrane that is both lightweight and breathable. Seamless in construction, the Toesock forms to every contour of your foot. This allows for true restriction free movement from your heel to five toes, encourages healthy circulation, and eliminates skin on skin contact between your toes to prevent blisters from developing. NuWool fabric does a bang-up job of thermo regulating and managing moisture.
