PU Ether lower shell and PU Cuff: PU Ether is a high end PU that provides more rebound to the boot when used with a high level of constraints, like in World Cup Race for example.

My Custom Fit Race Liner for max customization with 3 compact layers of thermoformable foam on the ankle, heel, meta and tongue for perfect transmission

Backbone release, taken from the X-3 lab, is a Magnesium piece linking the cuff to the shell.

Salomon’s patented Ride & Hike technology combines the backbone release with a specific V-cut shape on the back of the lower shell. This allows wide rear cuff opening when hiking (backbone unlocked) and true alpine forward flex when skiing down (backbone locked) because the backside of the backbone fits precisely into the V-cut lower shell.

A reinforced rear, lateral insert enables the use of a softer front cuff for improved leg wrapping and progressive flex.

Double dismantle canting for perfect cuff alignment – allows boot fitters to work easily on the cuff.

A 130 flex provides tremendous power, precision, and control to expert skiers who push their equipment to the limit. A 100mm last is wide enough to be comfortable on the way up, but narrow enough to maintain precision on the way down.
