These socks combine Tencel, cotton and high-tech absorbent yarns with an innovative structure to offer perfect moisture management, freshness and comfort. Derived from 100% eco-friendly eucalyptus pulp, Tencel gives socks excellent breathability and a cool, isothermal feel. These socks also feature the incredibly light, elastic and quick-drying Pure-IC biobased yarn. Innovative Moisture-Vent technology provides ventilation and support. The layout of the technology provides a highly breathable environment without impacting balance. With every step, moist air is pumped from the arch of the foot to the sides, so that moisture can escape. Connected to the moisture-wicking technology, the climate channel system guides warm, moist air out of the trekking shoe. Smaller, more spread-out pads allow moisture to escape to regulate temperature. Cool socks for summer.
