Roxa’s R3 range is the lightest series of high performance alpine ski boots they’ve ever made. The R3 models use a 3-piece NextGen Cabrio architecture with a unique and lightweight 50 mm upper buckle closure that allows the shoe to be tightened quickly for descents, while increasing freedom of movement when opened for climbs. The Roxa 45-degree "Heel Lock" instep loop securely holds the heel for both skiing and hiking to stop rubbing. A chunky rubberized sole provides grip for walking on rocky ridge lines and easy to use walk mode leaver makes it easy to switch from uphill to downhill modes.
