The Fischer RC4 PRO MV DYN BOA is a unique offering for backcountry freeriders who want the ultimate in downhill performance. The inclusion of touring pins and a GripWalk sole, with the omission of a hiking mechanism, is a boon to folks who gravitate toward the increasingly-popular hybrid category of bindings, or perhaps a Cast system, to get to the top of rowdy lines, and want a solid-spined boot for an aggressive descent. The shell, crafted from TPU, features a medium last and is shaped using input from thousands of foot scans to ensure a solid anatomical fit, right out of the box. Fischer has incorporated the BOA Fit System, allowing the lower shell to wrap around the foot for a more comfortable and precise fit. This is combined with a floating entrance flap to reduce pressure over the instep for seamless entry and exit. While the lower shell focuses on comfort and usability, the cuff is all about precision and performance. The 130 flex rating of the RC4 sits near the top of the scale for alpine ski boots and the carbon cuff provides exceptional stability while a burly powerstrap enhances edge feel as you lean into it. Fischer has teamed up with liner masters over at ZipFit to bring the world-class technology to this monster of a boot. ZipFit utilizes cork around the heel and ankle, providing a glove-like fit that brings instant energy transmission and comfort, while neoprene in the toe box keeps your foot comfortable and warm. In short, the RC4 PRO MV DYN BOA is truly built for the today’s progressive freeskiers that are looking for the next evolution of tools in their trade.
