We have already seen a custom shell boot from Salomon that has been well received, but the Vacuum is a whole different animal. The Fischer is a full “custom shell.” The shoe and the cuff are made of a combination of plastics that truly mold to the foot and leg.

Furthermore, this boot doesn’t just get wider where it needs to be wider or taller where it needs to be taller. It actually gets smaller where it needs to be smaller. (To everybody out there who has dreamed of a boot that really, truly locks down the heel, take a few deep breaths and try to contain yourselves.) Not only does the Vacuum’s Fit process take care of shape, but it also deals with stance. The cuff is supposed to move to a more neutral stance relative to the skier’s lower leg, assuring the skier is standing flat, resulting in easier simultaneous edge initiation.
