The Protector Attack binding offers Full Heel Release (FHR) technology, a first in our Attack series. Our innovative FHR technology delivers intelligent 180 release, both horizontally and vertically. This new technology can lower release values in forward and especially backward twisting fall situations, which reduces the risk of suffering a knee injury. While maintaining the reactivity and robustness of the Attack series, this binding features an adjustable toe and heel that can be adjusted to a wide range of sole lengths from 259mm to 386mm. Skiers can rely on this binding in all situations. Thanks to the FR PRO3 toe and AFS metal MN, the binding is compatible with adult alpine ski boots (ISO 5355 TYPE A), adult walk ski boots (ISO 23223 TYPE A) and all touring ski boots (ISO 9523). Optimal height adjustment must be performed with a test strip to accurately adjust the boot-binding system and achieve optimal performance on skis.
