The Fischer RC Pro 100 is an excellent ski boot for the strong intermediate to expert skier who has a medium to medium wide forefoot and medium shaft of the leg. A rubber Grip Sole is very durable and makes walking on slippery surfaces much easier for you. The 3D Liner has an anatomically correct shape that adds comfort and performance to your skiing. Powered by Vacuum the RC Pro 100 can be taken to an Authorized Fischer Dealer to heat the shell. Once the shell is hot enough the bootfitter will place them on your feet. When the shell starts to cool it can mold and match the shape of your foot for a perfect fit.
