Scarpa 4-Quattro SL Alpine Touring Boot

It is designed as a true hybrid. With a 120 flex and carbon-reinforced shell, it has the power transmission needed for resort laps, while the 61-degree range of motion and lightweight construction make it efficient enough for long backcountry tours.

These boots feature a GripWalk sole, which is compatible with modern GripWalk-certified alpine bindings and most touring bindings. They will not work with older, non-GripWalk compatible alpine bindings, so check your binding specifications before purchasing.

The 100mm last is considered a medium-volume fit. It is generally accommodating for average-width feet, offering a balance between performance-oriented precision and all-day comfort without feeling overly restrictive.

Yes, the boot comes with a thermoformable Intuition liner. We highly recommend having a professional boot fitter heat-mold the liner to your foot shape to eliminate pressure points and improve overall comfort.

This design allows the shell to open wider than a traditional overlap boot, making it significantly easier to put on and take off. It also helps maintain a consistent, progressive flex that feels more like a dedicated alpine boot.

For most skiers, a 120 flex provides ample support and power transfer for aggressive riding. If you are an exceptionally heavy or powerful skier who exclusively charges at high speeds, you might find it slightly softer than a dedicated 130-flex race boot, but it is plenty stiff for the vast majority of terrain.
