No subject to promotional offersThe Hi Speed 120 Hv Gw is a men's ski boot from Rossignol.
With Rossignol Hi-Speed range of downhill ski boots, configuration is the key concept in making these boots perfectly adapted to each skier, whether to improve performance and/or comfort.
With a 120 flex and 102 mm intermediate last it is precise, responsive and powerful! The Dual Core collar reinforces the shell at the bottom, optimising resistance to flexion and torsion on the one hand and rear support on the other, thereby increasing the boot's precision.
Rossignol has worked on comfort, particularly thermal comfort. The Hi-Speed range has a pre-curved liner around the malleoli for greater comfort and excellent fit.
The Hi Speed 120 Hv Gw offers the possibility to adjust the flex between 115 and 125 thanks to two screws located at the back of the boot for customised power, performance and comfort. You can also adjust the forward lean of the cuff to make the boot more aggressive, as well as the lateral lean to adapt it perfectly to the morphology of your lower leg. Finally, the buckles can be adjusted on 3 positions to give more or less room for the calves.
The Hi Speed 120 Hv Gw is designed for experienced skiers who get cold easily, who want to have fun on the slopes with an efficient, high-performance and comfortable boot.

Technologies:
| GENERATIVE DESIGN STRUCTURE | The Generative Design is a unique Rossignol technology. This is part of its DNA. This structure allows for material thickness optimisation: it is stiffer on the lower part of the shell and on the rear part of the cuff. It is composed of different thicknesses, for optimised weight. It combines perfectly with Dual Core technology. |
| DUAL CORE TECHNOLOGY |
The new ‘Power Injection’ method enables two plastic durometers to be injected perfectly simultaneously. This unique mono-injection process ensures targeted power transmission and optimum envelopment of the shell, which benefits from an integral DUAL CORE sandwich construction for more dynamic rebound, greater responsiveness and total control in curves. |
| ASYMMETRICAL DUAL CORE CUFF |
The Dual Core technology has been taken one step further. Our new DUAL CORE ASYMMETRIC BRASS focuses more specifically on manufacturing a soft plastic in the areas that envelop the lower leg and a harder plastic in the areas that provide support and power transmission for optimised rebound and response. |
| FORWARD LEAN ADJUSTMENT |
Get personalised power, balance and support with the FORWARD ADJUSTMENT. Adjust from 10.6 to 12.6 degrees, to obtain up to 6 mm more support forwards and backwards. |
| FLEX ADJUSTMENT |
Thanks to the FLEX ADJUSTMENT feature, a simple adjustment of the rear screw provides a larger flex capacity to maximise your power. |
| THINSULATE® PLATINUM | Thinsulate™ Platinum insulation keeps feet warm in wet and cold weather to provide all-day comfort and excellent odour control. |
