Built for precision-driven piste skiers with narrow feet, the RC4 Carbon Pro LV BOA 115+ blends race-bred control with refined comfort. This is a boot for skiers who demand exact edge engagement, instant response, and confidence at speed—without sacrificing fit or warmth.

At its core is Fischer’s CARBONFUSED® Alpine cuff, combining carbon fiber reinforcement with Pebax® Rnew to deliver exceptional lateral stiffness and rebound. Paired with a tuned 115+ flex, the boot provides powerful energy transfer while remaining accessible enough for long, high-performance days on hard snow.

The BOA® H+i1 Fit System replaces traditional buckles with micro-adjustable precision, wrapping the shell evenly around the foot for unmatched pressure distribution and a locked-in feel. Inside, the RC4 ZipFit® liner elevates comfort and control with a dynamic cork composite that molds over time, enhancing heel hold, warmth, and responsiveness—while effectively adding stiffness for aggressive skiing.

Designed using FISCHER Scan-Fit® data, the narrow 94 mm last offers anatomical precision straight out of the box, while extensive bootfitting options ensure a truly customized setup. From first carve to last run, this boot delivers uncompromising piste performance with modern adjustability.
