UYN Compression Fly

With the revolutionary UYN Runner's, running will never be the same again. ONE: the shoe that combines all the benefits of socks with the performance of our neuro-reactive sole. Thanks to the innovative ZEROCUFF technology, the sock stays perfectly in place on the leg without the classic cuff. The absence of restrictions at the calf allows for better blood circulation, which exponentially enhances foot performance and comfort. The sock, made from Natex biofibers derived from castor beans, offers exceptional ventilation, stability, and support. The combination of the rigid Power Chassis platform with the ultra-light Propulsyon foam ensures reactivity and propulsion with every step.
