Common questions
Borderline fittersThis is a pre-order item; it is expected to ship around November 1, 2026. Your card is charged when you place the order.
RYF (Remember Your Fit) uses a central lever: release the tension with one hand motion and reactivate it the same way, without hunting for your fit again. It also allows millimetre-precise adjustment.
It's built on a 96 mm last, a close, narrow fit, with a 110 flex and sporty tuning for passionate skiers. If your forefoot is wide, a 96 mm last may feel tight.
Mondo 25.5, 26.5, 27.5 and 28.5. Measure your foot from heel to longest toe in cm while wearing ski socks and pick the closest size; liners pack out slightly with use.
About
K110P RYF
Designed for passionate skiers, the K110P RYF impresses with exceptional flexibility and control. With its 110 flex and sporty tuning, it provides reliable support even in the most extreme situations.
The biggest innovation is the RYF system (Remember Your Fit), which puts an end to the constant search for the perfect fit. Using the central lever, the tension can be released and reactivated with a single hand motion, while allowing millimeter-precise adjustment. The further developed Performance Plus 2.0 liner is also fully customizable – thanks to K_Fit and K_Tilt technologies – ensuring perfect fine-tuning for every skiing style.
