Running socks are often seen as functional and plain, but we believe runners deserve to stand out just as cyclists do. Our Prolen socks are smooth and comfortable for runners, but we've taken it a step further by adding 5% cotton to the same design, making a world of difference. This version maintains the open weave at the top, offering better ventilation compared to the CX Cycling Socks. We've had these socks tested by numerous top runners, all of whom agree: the Lightning CX Run Socks are perfect for those who want to perform and be seen!
