Hi-Performance connection for every turn. This is a story about connection. We pushed the boundaries of ski boot design. Now we’ve reimagined the link between skier, liner, and shell. Developed across every last, for every foot shape. PERFORMANCE & CUSTOMIZE COMFORT - R’GO FIT new liners PRECISION & POWER TRANSMISSION - Dual Core Shell Technology CONNECTION & CONTROL - All new innovative shell liner system for 4 buckles INCREASED TRACTION AND WALKING CONFORT - Grip Walk®
FULL CUSTOM LINER - For improved precision and performance, these liners are fully customisable to mould perfectly to the shape of the foot. The internal padding, external stem and tongue are all customisable. Customisation is carried out using the new thermoforming machine - True Form Moulding Unit - using heated covers for CUSTOM LINER - Only the internal padding of these liners can be customised.

DUAL CORE involves injecting materials with different hardness levels or of different types into the same mould. This makes it possible to create zones of different hardness on the boot, without adding layers of plastic. This technology can be used to accurately fine-tune the progressive flex, rear support and rebound. The DUAL CORE technology works in synergy with the Generative Design. It reduces weight while retaining rigidity. This is key to ensuring a high level of skiability. On the HI SPEED, PURE boots, the Dual Core technology is used on the lower part of the shell, which reinforces torsional rigidity. The generative design saves weight by optimizing the thickness of the plastic and is mainly located under the buckles to prevent the shell from deforming during closure. This design helps produce the right weight, which varies according to the type of boot. Forward Lean Adjustment - This setting allows you to adjust the forward lean of the boot to make it more aggressive. In standard position - when the boot comes out of the box - the spoiler is in the low position and the angle is 10.6° Adjusting the spoiler to the upper position creates a 6 mm forward lean and a 6 mm height gain, INTERNAL LASTS - Internal last refers to the width of the boot’s forefoot area, measured in millimeters. It is a key factor in determining the fit and comfort of the boot. CANTING - Adjustment of the lateral angle of the cuff by +/- 1° to adapt to the shape of the lower leg. CATCHES - The catches on the cuff can be adjusted to 3 positions to increase or reduce space for the calves. GRIPWALK® Integrated stiff pads guarantee optimized power transmission and full Alpine release function (ISO 9523 and ISO 5355) FLEX ADJUSTMENT - The boot’s flex can be adjusted up or down by changing the position of the screws on the back of the cuff. Central position the flex shown on the boot. Moving the screws as pictured in the diagram allows you to adjust the flex by 5 points (+/-).
for a forward lean angle of 12.6°.
The DUAL CORE technology involves injecting materials with different hardness levels into the same mould, with three injection points in the shell and two injection points in the cuff. The result is a sandwich construction with an ultra-thin layer of hard materials on the outside encapsulating the softer materials inside. This technology can be used to accurately fine-tune the progressive flex, rear support and rebound, and also allows for highly effective lateral power transfer.
Our progressivedata-driven design approach harnesses the power of generative design to create the ideal boot shape. Focused on minimizing shell wall thickness for reduced weight while simultaneously enhancing power and support, our new Generative Design Structure offers the most effective blend of both.
The 104mm LAST features a wider forefoot, toe box, and ankle area while retaining a strong heel pocket for generous all-day comfort and support
