The exception to the rule: the Anthem 80 is an all-mountain technical ski with pleasing flex and an even more value for money. Its women's adjustable cuff allows for a perfect fit, regardless of leg length or calf shape. The Energy Interlock connects shell and collar without riveting. Once the shoe is flexed forward, the interlock spans. It stores the resulting kinetic energy and releases it during the swing. Not only does this construction reduce tensions on the shoe, it also ensures more efficient power transfer and therefore a natural flex. - FastFit Entry - Softer TPU materials developed in the instep area of ??the Powerlite shell for quick and easy entry and exit. A Y-shaped, dual-injected component at the rear, which gives the Energy Interlock extra stability and power. The PowerFuse SpYne optimizes forward and backward movement efficiency and lateral stability. This ensures responsiveness. The strength of the PowerFuse SpYne allows us to use a softer cuff and shell material to better cushion vibration in rough terrain.
