Technology

BOA Fit System - H+i1
Dialed in. Locked in. Confident. This high-power BOA system is purpose-built for alpine ski boots, delivering enhanced foot wrap and innovative pressure distribution for superior performance.

VACUUM
Perfect shell customization at 80°C to match foot anatomy – for precise power transfer and enhanced rebound through increased elasticity. Also provides improved temperature stability and 15% weight reduction.

GripWalk Sole
Delivers natural walking motion, traction on slippery surfaces, and downhill performance. Thanks to its curved profile, convex tread pattern, and grippy co-polymer rubber. 100% compatible with all Fischer boots in both adult and junior standards.

FISCHER Scan-Fit Last
Developed from thousands of foot scans via the FISCHER Scan-Fit app, this next-generation last ensures an anatomical fit that enhances power transfer and control.

Grindable Bootboard
Allows bootfitters to easily modify bootboard height and angle. The surface indentations provide reference points for standardized adjustments.

Fischer’s latest race canting minimizes shell-to-cuff tolerance. Available in 2- and 3-point asymmetric versions. Replacement parts: U78321 / U78322.

Women's Specific Collar
