The Z1 is a real revolution in children's shoes. It provides comfort, warmth, natural geometry and posture for accessible and fun learning. It's got plenty of kids-specific technologies: our Jr. Hi-Top instantly transmits energy from the skier to the ski for easier turns, while a more relaxed forward lean allows for a more comfortable and natural posture. Plus, our Vario lasts perfectly follow the development of kids' feet, improving comfort and performance, while DuoFlex gives kids natural, centered balance and control for a smooth, responsive flex.
