What Our Gearhead® Experts Are Saying:"I ride the RC4 120 LV BOA when I want max responsiveness without sacrificing comfort. The low-volume shell gives me race-boot control, and the BOA® system really locks my foot in with zero pressure points. It skis like a high-performance machine and feels custom-made."When we need race-level control and uncompromising fit, the Fischer RC4 120 LV BOA Ski Boots are our weapon of choice. Built with a 98mm low-volume last and Vacuum Fit+ shell, this boot wraps the foot with anatomical precision while still maintaining comfort throughout long days on the hill. Whether we're charging early-morning corduroy or carving through off-piste crud, the RC4 120 LV BOA responds with power and finesse. Fischer’s BOA® H+i1 Fit System delivers the most secure and adjustable closure we’ve felt in a performance boot, reducing foot movement for optimal energy transfer. The boot’s 120 flex is stiff and snappy for high-speed control, while the GripWalk® soles keep things practical on bootpacks and lodge strolls. Inside, the Grindable Bootboard and RD20 Race Canting allow us to fine-tune every detail, giving us a fully customized fit that maximizes precision in every turn.
