The fourth generation of our Pro Racing Run Low socks has been tried and tested by our team over hundreds of kilometers. They offer revolutionary ventilation and protection against blisters during your runs on hot days. The technical fabric is lightweight and airy, quickly wicking moisture away to keep your feet cool and dry. A newly designed, wider toe box provides a more ergonomic fit and better proprioception, allowing the toes to intuitively grip upon landing for a natural, fluid stride. The fine mesh around the heel, identical to that of the PRS High version, offers targeted support when you increase your pace, while the terry cushioning at the big toe protects you from blackened nails during longer runs. The midfoot arch support stimulates microcirculation and prevents the fabric from twisting and pinching to avoid blisters.
