Unparalleled comfort for long, relaxed training runs: RU3 Comfort running socks are extra padded and soft. The padding was developed in collaboration with sports scientists to support your pressure points when running: under the feet, around the toes, and on the soles.

The special 3-layer construction efficiently wicks away moisture to keep your feet dry at all times. The socks have an ergonomic fit – a true left and right foot shape. This minimizes friction and prevents blisters, whether you're running 5 km or an ultramarathon. For even more attention: these RU3 Comfort socks change color when the sun shines.
