Intended for trail running and adventure racing, Bridgedale's Trail Sport sock is a highly-breathable, moisture-wicking endurance design that helps keep your feet comfortably cool while racing, hiking, cycling and climbing. Equal portions of merino wool, nylon and Isofil fibers work together in an innovative WoolFusion design to minimize moisture saturation and uncomfortable friction during extended outings or during runs in high heat and humidity. A special ShockZone padding along the bottom of each sock helps absorb repeated foot strike impacts, giving you the edge on comfort over anyone wearing ordinary running socks.
