Still no mushbucket at a 120 flex, the RX 120 has the classic Lange progressive flex that many experienced skiers have grown to love, plus a snow feel that's second to none. Solid mono-injected polyether shells provide a great base for bootfitting modifications without worrying about seams or plastic that turns tacky with heat.

Product Details


Control Fit TechnologyLange scanned the feet of 20,000 skiers from around the world with a new, state-of-the-art 3D imaging system to develop this combination of shell last and liner execution designed to fit more feet accurately and comfortably. Using this analysis, Lange learned that most skiers benefit from a wider, asymmetrical toe box combined with a slightly narrower, more deeply articulated ankle pocket than is found in competitors' products. The combination of more room in the forefoot and more accuracy in the ankle delivers the best of both worlds: comfort and performance.

Last: 100 mmMedium volume forefoot width that doesn't sacrifice ankle and heel hold; a great balance between ski control and comfort for average volume feet.


Flex: 120Stiff but not too stiff flex for advanced to expert skiers.


Thermo Fit RL2 LinerLiners are heat moldable and offer increased foot retention to meet the right balance of performance and comfort for every skier type.

Control Fit LinerDesigned to provide accurate fit and immediate response, this liner has anatomical padding for strong, comfortable ankle and heel hold. Above the instep, Lange has included a slight pocket for increased circulation and warmth, in addition to a power wedge tongue for enhanced precision and sensitivity. The saddle stitch seams eliminate pressure points and the one-piece toe box allows for greater comfort in the toes.

Custom TongueDesigned with a hollow instep area, this new padded tongue guarantees maximum customization to the skier's instep where circulation is often cut-off and pressure points common. More comfort, more warmth, more control.

Power Wrap TongueSuperior leg wrapping for enhanced precision and sensitivity.

Shell Materials

Mono-InjectionInjection technology based on the use of a single plastic material. This results in the smoothest flex pattern for ultimate response and feedback, more consistent flex and performance in varying temperatures, and a bootfitter-friendly, easy to modify shell.




Natural StanceThis stance compliments modern ski design by providing a neutral and upright stance for more efficient power transfer on modern shaped and rockered skis. This provides less quad fatigue for better, longer ski days. 4° Ramp Angle, 12° Forward Lean (14° with spoiler) and 0° medial / lateral stance.

Twin Cuff Alignment | +/- 1.5°Permits skiers to align the lateral inclination of the upper cuff to the skier’s leg. Outside and inside hinge cuff alignment; rotate the mechanism clockwise, or counterclockwise, to align boot cuff to desired position.
