Choosing bindings is often a compromise, but not with the Shift²: it offers full climbing and freeride capabilities in one package. If one side needs to be emphasized, the Shift² excels in providing excellent downhill stability. Compared to the previous model, this Shift² version features a new Micro-AFD plate that improves boot fit, along with an internal aluminum Power Block, which provides 30% better lateral stiffness and power transfer. The front width extensions enhance shock absorption. The redesigned brake improves locking reliability and further reduces the risk of accidental release. The updated climbing position adds 4 mm more elevation. - Multi-Norm binding: Compatible with both tech boots with pin inserts and alpine boots - Hike and Ridesimple switch between standard mode and two climbing positions - DIN adjustment range: 4 - 10 - Compatible with crampons - Weight 897g/pcs The size option indicates the width of the brakes.
