Built for those who blur the line between frontside performance and backcountry freedom, the Scarpa 4-Quattro Pro is the lightest, most powerful boot in its class. Every detail of the design reflects a commitment to precision and speed—from its newly reinforced cuff that amplifies power transfer, to the Secure Speed Lock 4 mechanism that delivers unwavering confidence on steep, technical descents.
At its core, the 4-Quattro Pro is about control without compromise. The Pebax® Rnew® shell and cuff offer responsive flex and reduced weight while maintaining durability and eco-conscious construction. The Alpine Axial system ensures a precise, performance-driven fit that feels as connected as a true alpine race boot, while still offering a remarkable 60° range of motion for efficient skinning and long approaches.
Paired with the Intuition® Pro Flex Ride liner, this boot molds perfectly to your foot, balancing comfort with the stiff responsiveness needed for aggressive skiing. Whether you’re dropping into couloirs, carving hardpack, or hunting for untracked lines deep in the backcountry, the 4-Quattro Pro delivers unmatched versatility and power for skiers who demand it all.

Ski boots are sized in Mondopoint, based on the length of your foot in centimeters. The chart below is a general reference for converting between sizing systems.
This chart is not a fitting. The only way to know your ski boot size is to be fit in person, either with a Boot Fitting at our shop or from a professional fitting you have had elsewhere. Sizing, shape, and volume vary by brand and model, and a performance fit is snugger than your street shoe. Unworn boots can be returned under our return policy, but a boot that doesn't fit can be a big hassle for your trip if you haven't tried it on.

Conversions are approximate and can differ by half a size between brands.
Ski boots are built with one shell for each full and half size, so a 27 and a 27.5 are the same boot with a different liner or footboard. That is why sizes are listed together, like 27/27.5.
Very few models differ from this. Scarpa is the main exception, pairing sizes the other way (for example, 26.5/27 share a shell). When a model is sized differently, we call it out on that product's page.
