The Rossignol Men's HI Speed 100 HV Ski Boot delivers high-performance control and comfort for all-day skiing. Made for skiers who need a high-volume fit, we've engineered the boot shell and cuff through generative design for maximum energy transfer and high-speed control through every turn. Adjustable flex and canting let you personalise the boot feel and response to match your skiing. A thermoformable liner lets you customise the fit. Thinsulate™ insulation enhances liner warmth, so you can focus on your skiing. Buckle into next-generation control with a fit that lets you ski all day.

GENERATIVE DESIGN STRUCTURE:
Rossignol's progressive data-driven design approach harnesses the power of generative design to create the ideal boot shape. Focused on minimising shell wall thickness for reduced weight while simultaneously enhancing power and support, our new GENERATIVE DESIGN STRUCTURE offers the most effective blend of both.

DUAL CORE TECHNOLOGY:
Rossignol's new "power injection" method allows simultaneous injection of two different durometers of plastic. This unique mono-injection process allows targeted power transmission and shell wrapping, creating our DUAL CORE sandwich construction throughout the shell and resulting in livelier rebound, response, and total control through the turn.

ASYMETRICAL DUAL CORE CUFF:
Rossignol has taken their Dual Core technology another step further. Rossignol's new ASYMMETRICAL DUAL CORE CUFF more specifically targets softer plastic to areas that wrap the lower leg and harder plastic to areas that offer support and power transmission for optimised rebound and response.

FLEX ADJUSTMENT:
FLEX ADJUSTMENT allows a larger flex range for customised power, performance, and comfort via a simple rear spine screw adjustment.
