Buckle into the Rossignol Hi-Speed 100 HV ski boots for high-performance control and comfort to ski all day long. 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 personalize the boot feel and response to match your skiing. A thermoformable liner lets you customize 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.

High Volume Fit

• High Volume Fit features a 102 mm last for forgiving anatomical feel regardless of foot shape.

Lightweight, Full Power

• Data-driven Generative Design minimizes boot wall thickness for the most effective use of material to reduce weight and enhance power transfer.

Better Skiability, Better Fit

• Dual Core technology provides targeted power transmission and shell wrapping, resulting in livelier rebound, response and control.

Optimized Rebound and Response

• Asymmetric Dual Core Cuff combines softer plastic to wrap the lower leg with harder plastic where needed for support and power transmission for optimized performance and fit.

Adjustable Flex

• A simple rear spine adjustment provides an adjustable flex range of +5 to -5 for customized power, performance and comfort.

Custom-Fit Comfort

• Custom-fit liner features customizable zones for comfort-driven fit with increased heel support and softer padding through the ankle and instep.

Insulated Warmth

• Thinsulate Platinum keeps feet warm in damp and cold conditions for all-day comfort with advanced odor control.

Optimized Fit and Warmth

• Seamless Toe Box eliminates pressure points for optimized out-of-the-box fit and reduces heat loss by 20 %.

GRIPWALK Compatible (sold separately)

• GRIPWALK soles feature a rubber tread and rockered toe for a more natural walking motion and increased traction.

Technologies

GENERATIVE DESIGN STRUCTURE

• Progressive data-driven design approach harnesses the power of generative design to create the ideal boot shape. Focused on minimizing shell wall thickness for reduced weight while simultaneously enhancing power and support, GENERATIVE DESIGN STRUCTURE offers the most effective blend of both.

DUAL CORE TECHNOLOGY

• ''Power injection'' method allows the simultaneous injection of two different durometers of plastic at the exact same time. This unique mono-injection process allows targeted power transmission and shell wrapping; and creates DUAL CORE sandwich construction throughout the shell, resulting in livelier rebound, response, and total control through the turn.

ASYMETRICAL DUAL CORE CUFF

• We've taken Dual Core technology another step further. 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 optimized rebound and response.

FLEX ADJUSTMENT

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