Built for skiers who demand absolute precision on hardpack, the RC4 Carbon Pro MV BOA 130+ is Fischer’s uncompromising piste weapon. Every element of this boot is engineered to deliver explosive power transfer, race-level control, and a locked-in fit that stays comfortable from first chair to last turn.
At its core is a stiff 130+ flex paired with a mid-volume 104 mm last, striking the ideal balance between high-performance responsiveness and all-day support. The CARBONFUSED® alpine cuff, reinforced with carbon fiber, boosts torsional rigidity and stability, allowing you to drive skis with confidence at high speeds and through aggressive transitions.
Fit precision is elevated by the BOA® H+i1 Fit System, which wraps the shell evenly around the foot for consistent pressure distribution and micro-adjustable tuning on the fly. Inside, the RC4 ZipFit® liner sets a new standard for comfort and performance, using a dynamic cork composite that molds over time, enhances heel hold, and automatically adds stiffness for even greater energy transfer.
From its VACUUM / ZoneFit®-moldable TPU shell to race-inspired alignment and stance technologies, the RC4 Carbon Pro MV BOA 130+ is built for expert skiers who want uncompromising edge control, powerful rebound, and confidence at speed.

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.
