Ski boot

Ski boot comprising a rigid shell which is shaped so as to accommodate the foot of the user, and a rigid cuff which is shaped so as to surround the ankle of the user and is pivotally jointed to the shell so as to be able to pivot about a rotation axis (A) substantially perpendicular to a midplane of the boot;

• the shell comprising a substantially basin-shaped, rigid casing which is shaped so as to be able to accommodate therein the foot of the user;
• and a transversal stiffening insert which is embedded inside the bottom wall of the casing at the tarsophalangeal region of the sole of the foot, and is structured so as to emerge/surface on the outside of the rigid casing on opposite sides of the midplane of the boot, at two lateral sides of the tip of the shell;
• the ski boot being characterised in that the transversal stiffening insert is provided with two first conjugated coupling ends that surface on the outside the rigid casing along the two lateral sides of the tip of the shell, on opposite sides of the midplane of the boot, substantially coaxial to a same reference axis (B) substantially perpendicular to the midplane of the boot, and with two second conjugated coupling ends that surface on the outside the rigid casing along the two lateral sides of the tip of the shell, on opposite sides of the midplane of the boot, spaced beside said first conjugated coupling ends;
• said first conjugated coupling ends being structured so as to be engaged and clamped in an axially rotating manner about said reference axis (B) by the toe piece of the ski binding device.
