The ski boot is made up of different components, each of which performs a specific function, including the various and disparate mechanisms that make it up, and have the specific purpose of regulating and improving, if necessary, the skier’s performance.

The adjustment of the mechanisms allows the boot to adapt to the anatomical needs and technical characteristics of the user, but some of these adjustments must be made with some care, since they can interact with each other.


Present on almost all boots on the market, it is a mechanism that allows you to adapt the cuff to the natural angle of the tibia, to allow the skier an optimal support with respect to the transverse plane.

This adjustment must be performed only in the presence of marked morphological anomalies of the tibia, since excessive or unnecessary adjustment affects the entire set-up and in any case must be carried out by expert personnel. All boots are assembled and marketed with a neutral angle, adjustable from + 3 ° to -3 °.

Flex Control

Mechanism that varies the forward resistance of the cuff and can be adjusted according to the customer’s weight, agility or type of skiing. If the specific mechanism is not present, it is necessary to intervene on the plastics with specific equipment.

It should not be confused with the Flex of the boot, which concerns the construction material.

Inclination Control

Adjusts the angle of inclination of the tibia with respect to the support surface. It may be necessary for those with a pronounced calf. Note that the Racing boots have a more pronounced inclination than the touring ones.

Walk Ski

Mechanism that locks / unlocks the cuff to fit the boot or for walking.

Custom Arch

Mechanism that allows to adapt the insole to the arch.

Other mechanisms or adjustable details present may be the tibial supports, the rear spoilers, the adjustable wedges or the micrometric levers and others.
