Marathon FIR Socks Knee - Black/Anthracite

Knee-high coverage extending over the calf makes this the longer option in the MARATHON FIR line. In the Light climatic range, it is designed for long-distance running in mild conditions when you prefer full lower-leg coverage rather than a low cuff.

ACCAPI FIR technology complements thermal comfort, while the polyamide and polyester blend balances durability with moisture management. Elastane allows the material to follow movement throughout the stride. Choose the Knee version for continuous coverage from the foot up the calf during long training sessions.
