The Rossignol Men's Alltrack Pro 100 Ski Boots are designed to ski the whole mountain, so you can go for inbounds powder laps as well as exploring the back bowls. These boots are built with a Generative Design Grid that minimizes boot wall thickness for the most effective use of material to reduce weight and enhance power transfer. They are designed with a medium fit that features a 100 mm last for a precise, comfortable fit that balances comfort and control while their Dual Core technology provides targeted power transmission and shell wrapping, resulting in livelier rebound, response and control. Their Thinsulate® Stretch technology insulates while providing enhanced foot support for better skiability, and their GripWalk® soles feature a rubber tread as well as a rockered toe for a more natural walking. Speaking of walking, these boots offer an optimized hike mode as their lower boot shell is designed to offer a 50-degree range of motion in walk mode for efficient touring and maximum power for skiing when in ski mode. Enjoy the full mountain with the Rossignol Men's Alltrack Pro 100 GripWalk® Ski Boots!
