The Keen Women's Springbok Ultralite Low Cut Sock delivers lightweight, breathable performance to run, hike, and hang in total comfort. This versatile, multi-sport sock uses a combination of lightweight nylon and air mesh, striking a balance between between softness and quick-drying characteristics when you're slogging down the trail or preparing for your next ten-kilometer race. Its left and right-specific design conforms to the contours of each individual foot, and strategically placed impact-cushioning helps to soften vibration. In addition, this sock features a seamless toe zone to prevent bunching and a heel pocket for a secure, stable fit.
