Construction + Materials

GripWalk® Sole: The GripWalk® soles (ISO 23223) offer end users the ultimate in natural walking comfort, safety across slippery terrain, and ski performance. Adult and Children's norm soles are 100% compatible across all boots in the FISCHER range.
VACUUM: Shells are moldable at 80°C through VACUUM and ZONE FIT process. Dynamic plastic that improves skiing experience, plus greater temperature stability and 15% less weight.
Grindable Bootboard: Grindable Bootboards were specifically engineered to allow boot fitters to easily modifiy the height and angle of the bootboard. Dimples on the surface of the bootboard provide a reference point so that bootfiters can control and standarize their handiwork
BOA® Fit System - H+i1: Dialed in. Locked in. Confident. This new high power and high strength BOA® system was developed specifically for use on alpine boots to promote shell wrapping and pressure distribution. Precision fit with on-the-fly tightening and loosening.
RD20 Race Canting: The lastest generation of race canting is designed to reduce the tolerance between cuff and shell of the boot, allowing for maximum power transfer and overall control. Available in 2 and 3 point asymmetrical versions to enable cuff alignment tuning.
The BOA® Fit System is incredibly powerful, as it designed to wrap stiff shells around your feet, to provide the utmost performance and confidence. However, if the BOA® Fit System is overly tensioned without a foot inside of the boot, the power of the system risks permanently deforming the plastic of the shell and can lead to leaky boots and improper fit. For these reasons, Fischer recommends storing BOA® enabled boots with no or minimal tension in the cable, especially for prolonged periods when the boots are not in use.
