TEKO socks are designed to be the go-between, between your foot and your footwear. A Teko sock plays a crucial role in managing moisture, friction, comfort, and performance. The all-new ecoRUN collection is made with ECONYL® regenerated nylon. This ultrafine fiber knitted on highly technical 200 needle machines takes Teko socks performance to a new level. The ultrafine ECONYL® yarns allow moisture to evaporate very efficiently from the foot and for the skin to stay dry even in the hottest and most humid climatic conditions.
