126Climate Technology®, developed by SympaTex, consists of both a membrane and a hydrophobic 3D upper material. These contain air pockets that ensure the highest water resistance, along with advanced breathability. Incredible moisture wicking properties from the foot through the hydrophilic inner lining which keep your feet sweat free in the warmest of environments. The 3D upper provides increased air circulation and ventilation through the rolling movement of the foot. Climate Technology® ensures a pleasant foot temperature for the wearer with maximum abrasion resistance, water resistance, and dynamic breathability. Designed for wearers that require the most breathable footwear on the market.
