Key Technologies

• 102 mm High Volume Last:
  A wider and more forgiving anatomical fit designed to provide all-day comfort while maintaining the support, power and precision required for confident skiing.
• Dual Core:
  Rossignol's dual-density shell construction uses materials with different levels of stiffness to optimize power transmission and shell wrapping. This creates improved rebound, responsiveness and control throughout the turn.
• Generative Design Grid:
  The shell is engineered to minimize unnecessary wall thickness and material, helping reduce weight while maintaining effective power transmission and performance.
• Hike Mode:
  The releasable cuff provides up to 50° of range of motion in walk mode for more natural and efficient movement when hiking or walking. The cuff can be locked back into ski mode for downhill performance.
• Custom T4 Liner:
  A customizable liner designed to provide improved comfort, support and a more personalized fit.
• GripWalk® Compatible:
  The boots can be fitted with compatible GripWalk® soles for improved traction and a more natural walking motion. GripWalk® soles are sold separately.
