Technology

Generative design grid

A progressive new data-driven design approach that harnesses the power of generative design software 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 grid shell offers the most effective blend of both.

Dual core technology

Our new "power injection" method allows the simultaneous injection of two different durometers of plastic at the exact same time. This unique mono-injection process allows targeted power transmission and shell wrapping; and creates our DUAL CORE sandwich construction throughout the shell, resulting in livelier rebound, response, and total control through the turn.

Hike mode 2.0

The new optimized hike mode includes a wider opening in the back of the lower shell, and a lower axis-of-rotation for optimized range-of-motion and uphill mobility (50° ROM). The articulating lower shell insert and metal-on-metal locking mechanism increase rearward support while supplying maximum power transmission on descents.

Full custom t2

Full custom liners offer customization both in the internal padding for enhanced foot wrapping and comfort, and the external liner materials for enhanced precision and power transmission. T2 version features two separate bi-injected zones w medium density eva padding in the performance zones and soft density eva padding in the fit zones.

Dedicated women's cuff

Featuring a shorter upper cuff and open, tulip shape on the rear of the liner, the women’s cuff accommodates a woman's natural calf shape for increased balance, comfort, and performance.

Regular fit

Our women-specific 102mm last, regular fit is perfect for recreational women skiers seeking increasing comfort and support.
