The K105 TERRA RYF women’s ski boot is part of the Kästle Terra collection.
It was inspired by the performance line of the top model but specially adapted to the anatomical characteristics of women. In terms of power transfer and stability, it matches the performance line in every way. With the innovative RYF system (Remember Your Fit) and its padded liner, this boot is the perfect companion—from the first run of the day to the après-ski. With a flex of 105, this women’s boot provides ideal stability for the sporty rider, whether carving long or short turns.

RYF® is an innovative closure system comprising a reel with a strain reducer, a metal cable, two cable deviations (with rolling friction) and a special buckle between them. The result? A system that can be adjusted with maximum precision to suit the skier’s needs and preferences.
RYF KEY COMPONENTS

Micrometric precision
The reel is the heart of the system’s precision. Thanks to its cable-winding knob, it enables smooth and immediate micro-adjustments, whether the central buckle is open or closed. Designed to reduce effort and guarantee flawless control, the reel manages every fine adjustment directly from the knob, allowing both tensioning and micrometric release with maximum ease.
Memory Fit and total comfort
Once micro-adjustment is completed, closing the buckle ensures full boot setting:
- It provides self-balancing of the closure,
- It allows the complete release of tension,
- It enables immediate resetting without losing the previously selected fit.
The system can be fully released by opening the buckle arm and pressing the winder knob to unwind the stored cable.
