The all-new womens RX 80 W combines Langes innovative Dual Core shell technology with new women-specific fit and features. Our new Shin Control thermo-formable liner adapts perfectly to the lower leg for increased support while alleviating common pressure points and shin sensitivity for better, longer ski days. Dual Core construction ensures unparalleled rebound and flex control for total control of your line.Liner SHIN CONTROL: Our unique women-specific SHIN CONTROL liner offers maximum comfort while maintaining the required precision and responsiveness for optimum ski control. The anatomical asymmetric tongue distributes shin pressure as you flex into the boot, dispersing it over a larger area for enhanced comfort and more control.Shell DUAL CORE: Our new DUAL CORE construction targets softer and more rigid durometers of ultra-lightweight Grilamid® plastic to key areas of the boot to enhance performance and entry-and-exit, resulting in a sandwich shell construction that increases energy, rebound, and flex control.Liner DUAL 3D LINER SPORT: DUAL 3D LINERS are pre-shaped to match the inner shell for the most precise and accurate power transmission, and around the foot for our most comfortable anatomic fit. The DUAL 3D SPORT version is 60% thermo-formable (shin, ankle, instep, toe box) with low-density foam integrated in key fit zones for enhanced comfort and support.Liner THINSULATE™: THINSULATE™ is a lightweight synthetic insulation that delivers increased warmth in damp and cold conditions for all-day comfort.
