Lange SX 120 - Ski Boots - Men's - black/green

One Piece Collar: A single material is used throughout the collar to cradle the calf, no matter the dimensions. While ensuring solid rearward support.

mono injection with soft insert: Mono-injection structure optimises performances and helps the boot-fitters in their job, whereas the flexible insert on top of the foot allows easy on/off.

quickmacro ratchet: Quick, anatomic ratchet adjustment to fit all calf sizes.

XL Buckles: Long lever buckles makes them easy to open and close.

Custom Tongue: Tongue padding features a hollow instep area to guarantee maximum customization to the skiers' instep. More comfort, more warmth, more ski control.

Thermo Fit Liners: The RL1, RL2, and RL3 models are all thermoformable liners around the ankles where hot air is injected (100°C for 10 minutes). Once the liner is heated, the boot can be put on and the volume personalised. Retention Level - RL foot support is proportional to the material density of the padding; RL 1, indicates a low density. Excellent foot support. Provide right balance of performance and comfort for every skier.

Flex Index: The flex is the boot's flexibility index. The greater the flex, the more rigid and reactive the boot. On the contrary, a soft flex will be more tolerant and comfortable. The flex of your boot is chosen in relation to your skiing level as well as size.
