Fischer RC4 Podium RD 110 Ski Boots (U01221)

In circuit motorsport, FIA-spec cars are not designed for comfort, but to transmit every imperfection of the asphalt and guarantee millimeter-precise steering response. The Fischer RC4 Podium RD 110 applies this exact engineering to the snow. They are true Plug Boots from the race department (RD). Their pure polyurethane "chassis" features an ultra-narrow 92 mm last. This creates a cockpit where vital space is reduced to zero, achieving a total biomechanical connection between the foot and the ski.

The "suspension" on this model features a 110 flex. It is a more docile setup than the brutal 130 or 150 flexes used in the men's World Cup, ideal for lighter drivers (women or juniors) or master skiers looking for explosive reactivity without the need to apply exhausting physical force.

The interior is equipped with a lace-up racing liner. It works exactly like a 6-point harness in a race car: it totally immobilizes the foot and heel, eliminating any slop or loss of energy during limit-pushing edge holds on sheer ice. (Technical note: Being a pure RD boot, the shell has thick walls designed to be milled and adapted by a professional bootfitter).
