Scarpa 4-QUATTRO SL Ski Boots

Designed for experienced skiers seeking a balanced blend of precision and comfort, the Scarpa 4-QUATTRO SL ski boots are ideal for those who switch between downhill skiing and ski touring using the same equipment. With a flex rating of 120, they offer a firm response without becoming difficult to control, even at the end of the day. Their hybrid construction, combined with a GripWalk sole, makes them compatible with both GripWalk-certified alpine and touring bindings. This gives you a versatile tool for tackling varied terrain and activities without significant compromise in power transfer or comfort.

Hybrid performance and 120 flex for precise control

The Scarpa 4-QUATTRO SL ski boots feature a 120 flex, designed to offer a balance between performance and forgiveness, ideal if you’re looking for a responsive boot that remains comfortable during extended use. This measured stiffness is combined with a Pebax Rnew shell and cuff, a plant-based material known for its excellent structural support while keeping weight down.The overmolded carbon insert reinforces the structure for better power transfer from ski to ski, helping you maintain control during heel-to-toe transitions and when carving. With a claimed weight of 1,430 g (size 27), or 2,980 g per pair, you get a lightweight hybrid ski boot considering its level of support.

Adjustable fit and personalized comfort

The fully thermoformable Intuition 4PRO Flex SL liner is designed to precisely adapt to the shape of your foot after a visit to a bootfitter. This type of liner optimizes fit and support, reducing pressure points and improving long-term comfort. The Pebax tongue also contributes to comfortable flex in the instep, following movements without creating a sudden break. This approach is particularly appealing for skiers who want to refine their last and enjoy a custom fit without changing the shell.

Closure System and Foot Support

The 4-QUATTRO SL features a 4-buckle magnesium closure system, complemented by a Power Strap. The four buckles allow for progressive tightening of the foot and shin, properly locking the foot into the shell for better precision in turns. Magnesium helps keep the weight down while maintaining good stiffness. The Power Strap, positioned at the top of the cuff, tightens the upper leg support and improves the connection between your legs and the ski, promoting more direct control and increased responsiveness on hard snow and during aggressive turns.

Ski/Walk Mode and GripWalk Sole

The Speed Lock 4 mechanism manages the transition between ski and walk modes. This ski/walk system is designed to facilitate switching between the two modes, a major advantage if you’re doing back-to-back ski-to-foot approaches or terrain transitions. The Presa GripWalk sole offers an interface compatible with GripWalk-certified alpine and touring ski bindings, allowing you to use the same pair of boots on different types of skis without having to carry extra gear. This specialized sole also improves traction while walking compared to a traditional alpine sole, for greater safety when moving off-piste.
