Fischer Soma RC4 Worldcup PRO 130 Ski Boots (U21008)
The Fischer Soma RC4 Worldcup PRO 130 (U21008) ski boots are the brand's most radical and extreme racing single-seater. Designed for FIS racers and elite experts, they combine an ultra-stiff 130-flex suspension with an extremely narrow 95 mm Plug last. Equipped with the Soma-Tec biomechanical chassis, they deliver a lethal power transmission and a surgical snow feel, becoming the ultimate weapon to annihilate the stopwatch on sheer ice courses.

At the pinnacle of motorsport, LMP1 or Formula 1 prototypes abandon all comfort to focus 100% of their engineering on telemetry and pure performance. The Fischer Soma RC4 Worldcup PRO 130 featuring a 95 mm last is the exact translation of this philosophy to the snow. Its "bodywork" is an injected block of ultra-high-density polyurethane that acts as a monocoque chassis. The "suspension," calibrated at 130 flex, absorbs absolutely no energy: it channels all leg force directly and violently to the edges.
The defining feature of this machine is its hyper-reduced "track width" of 95 mm, known in competitive racing as a Plug boot. It acts like a carbon bucket seat pressure-molded directly onto the foot, immobilizing every tendon and joint. This eradicates the slightest dead space, ensuring that understeer completely disappears during the most savage edge holds at breakneck speeds.
To maximize control of this hypercar, the geometry integrates Soma-Tec technology. This biomechanical innovation places the feet in a natural "V" stance, which improves the transfer of the center of gravity over the ski's longitudinal axis and acts as an anti-roll bar protecting the knees from the brutal G-forces generated in turns. The FFS Worldcup liner reduces padding to the bare minimum to guarantee a direct, unfiltered feel of the piste.
