The Rossignol Men's Hi Speed 100 Pro MV BOA Ski Boots '27 are designed for advanced all mountain riders who want a balanced mix of comfort, control, and responsive performance across a variety of resort conditions. Built with a medium 100 mm last and a supportive 100 flex, this boot helps skiers maintain stability while improving turn initiation and overall confidence on the mountain. The traditional two-piece overlap construction delivers consistent flex and reliable power transfer, making it easier to turn smoothly and stay in control at higher speeds. Rossignol Dual Core Technology uses a unique power injection process to combine multiple materials, creating enhanced rebound, energy transmission, and a more dynamic feel through each turn. The BOA Fit System replaces traditional lower buckles with a micro adjustable dial that evenly wraps the foot for a more precise and secure fit. A full custom heat moldable liner with Thinsulate Stretch insulation provides warmth and personalized comfort, while the seamless toe box reduces pressure points for better circulation. For riders seeking a versatile, customizable all mountain boot that blends comfort with performance, this model stands out as a strong option in the Rossignol lineup.
