Ideal for the gym, running and cross training, this ankle-height technical sock features a moisture-wicking blend of CoolMax, nylon and Lycra combined with the plush cooling comfort of combed cotton. Breathable mesh knit stitched across the top of the sock enhances ventilation, making the Active Sock a perfect fit for summer distance running. An innovative Moisture Management System features a moisture-conducting fiber layer against the skin that rapidly transfers perspiration to an outer absorbent layer. Once on the outer layer, the moisture remains away from your skin.
