UYN Runner's One

The UYN Compression Fly is a revolutionary shoe with socks. Designed for speed and comfort for trail running when paved roads give way to gravel tracks. The socks offer three levels of compression: light compression on the leg for better circulation, medium compression on the ankle for stability while running and strong compression on the foot to provide power with every step. The ultra-breathable upper material without seams respects the natural shape of the foot and offers an all-round fit without pressure points. The H.A.L.O. system combined with the Power Chassis platform offers superior stability when changing direction and on uneven terrain. Experience the responsive cushioning of the Freebound Heel structure with the new Propulsyon foam for lightning-fast trails.
