What Our Gearhead® Experts Are Saying:"I took the RC4 Free Pro MV BOA boots out for a week of mixed lift and touring days, and they completely blew me away. The Dynafit® tech inserts and 130 flex let me drive my burliest skis with confidence, while the BOA system gave me the most secure, pressure-free fit I’ve ever had. They’re precise, comfortable, and just flat-out rip."For freeriders chasing power without sacrificing precision, the Fischer RC4 Free Pro MV BOA ski boots hit the sweet spot. Designed with a stiff 130 flex and medium-volume 100mm last, they bring elite performance to the frontside and beyond. Whether we’re ripping through powder or charging down firm alpine steeps, these boots deliver a confident, connected ride from edge to edge. BOA® H+i1 Fit System wraps the foot evenly for micro-adjustable fit and better energy transfer, while the ZipFit® liner offers semi-custom comfort right out of the box. A carbon-fused cuff and RD20 Race Canting tech ensure race-inspired response without compromising feel. Add Dynafit® tech toe fittings and GripWalk® soles, and we're set for hybrid setups like Shift or CAST systems—bridging the gap between resort and backcountry lines with serious precision.
