The Lupo AX HD with a PU-polyamide-based shell is designed for maximum durability. With a 100mm last it offers slightly more foot space and therefore outstanding comfort. This is particularly beneficial for skiers who spend the entire day on the slopes and wear their boots almost daily. The boot is extremely versatile and offers a 67° range of movement with the tongue removed when walking. The shaft and 40mm-wide power strap offer outstanding power transfer for descents. High-quality GripWalk soles with a Vibram profile can be optionally fitted to make walking easier and reduce the risk of slipping.
