The RX 90W is a women's All-Mountain ski boot developped by Lange.
The shell of the RX 90 uses Dual Core technology for improved performances. In fact, its sandwich construction using bi-injection with flexible and rigid zones positioned in the crucial areas of the foot guarantee better reactivity and precision of the foot with effort thanks to better heel support. It also allows for better fitting and removal for optimal comfort.
In terms of the liner, the boot has the Dual 3D Liner, which is 100% thermoformable for increased comfort and remarkable transmission of the power created by the skier.
The boot is adjusted by means of four buckle fastenings and an ankle strap so that you can accurately adjust your boot and ensure an optimal level of performance. There is also the asymmetrical Shin Control tongue, specially designed for women, for optimal comfort.
The RX 90 is designed for all-terrain skiers who value performance without neglecting comfort.

Technologies:
Dual Core shell:
The simultaneous injection of 2 plastics at 5 different points creates a sandwich of materials over the boot's shell: it allows full control of the solid or flexible areas of the boots to guarantee good behaviour in snow. The DUAL CORE technology results in better behaviour in snow and improves the responsiveness of the boot.
Dual Performance liner:
A liner preformed to the shape of the shell on its outer surface and to the shape of the foot on its inner surface to maximise transmission and for an instant fit. It is 80% customisable.
Adjustable flex:
Screw allowing the flex to be adjusted.
Bimaterial Pads:
Removable pads that can be changed when worn, more comfortable for walking.
