UYN Runner's One

The UYN Compression Fly is a revolutionary shoe with socks. Designed for speed and comfort during trail running, it transitions from paved roads to gravel paths. The socks provide three levels of compression: light compression on the leg for better circulation, medium compression at the ankle for stability while running, and strong compression on the foot for power with every step. The ultra-breathable, seamless upper respects the natural shape of the foot and offers an all-around fit without pressure points. The H.A.L.O. system combined with the Power Chassis platform provides outstanding stability during direction changes and on uneven terrain. Experience the responsive cushioning of the Freebound Heel structure with the new Propulsyon foam for lightning-fast trails.
