The revolutionary Green Menace 4.0 GW is a super-light, environmentally cutting-edge overlap model whose high-tech shell is made entirely from recycled material. The fabrics and foams in the liner are also made of 100% recycled materials, which means the whole boot can be completely recycled later on. Four aluminium buckles and a stiff build deliver excellent stability, direct power transmission and firm foot support for aspiring skiers. An optimised fit and a comfy liner with thermal insulation mean young racers can keep on skiing all day long. Pre-fitted GripWalk soles allow young skiers to walk safer and comfortably.
