The 4-Quattro Pro is the hard-charging end of SCARPA's 4-Quattro family, billed by SCARPA as the lightest high-performance freeride boot for steep lines and wide skis. The shell and cuff are Pebax Rnew with a reinforced cuff, flex is 130+, forward lean is 19 degrees, and the last is 100mm. Secure Speedlock 4 handles ski and walk, on a PRESA SKI-01 / GripWalk Tour outsole (ISO 23223).
The trade-off is precision over forgiveness. A 130+ flex on a 100mm last is built to drive wide skis on steep, demanding terrain. Anyone who values warmth and extra room over outright stiffness will be happier in the 4-Quattro GT.
It is for strong skiers who lap steep resort terrain one day and skin to a remote couloir the next. The GripWalk Tour outsole works with alpine and touring bindings, so one boot can live on both setups.
The 100mm last is a performance fit, and the Intuition 4Pro Flex Ride liner heat-molds for a custom shape and all-day comfort. Sizing is Mondopoint, and a SCARPA half size shares its shell with the whole size above it.
For freeride days where the climb earns a steep line and the descent deserves full power, the 4-Quattro Pro is about as good as a boot gets.
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.
