Hilly Active Zero Cushioning Socklet Perfect for training, running or racing, the Hilly Active Socklets are a breathable pair of socks with exceptionally lightweight construction. The Hilly Active Zero Cushioning Socklets are super lightweight and have excellent moisture-wicking properties, making them the perfect addition to your warm-weather workouts. Constructed from a premium blend of Lycra Sport content and Tactel micro yarns, these socklets provide you with a soft, smooth, comfortable and secure fit, and one that will allow you to enjoy your workout that bit more. The two-sided knit ensures great moisture management and works to draw excess sweat away from the surface of your skin. This also means that the socks are exceptionally quick to dry, and durable, enhanced by the hand-linked flat toe seams. The seams provide you with a non-abrasive experience, keeping your feet comfy and cosy. Finally, the socks also have front and back alignment tabs, to signpost where the socks should sit.
