Abstract
Boot of the front entry type with variable volume having a shell that includes an upper and a shell base that overlap at least partially in the area corresponding to the dorsal zone of the boot, the upper being pivotally connected to the shell base. A bending mechanism is integrated in its dorsal zone where it is sandwiched between the upper and the shell base on which it is attached and rigidly affixed, and such bending mechanism is formed by a flexible strip that includes a vertical notch, open upwardly and whose delineating edges extend freely beneath the upper. The bending mechanism enables the flexibility characteristics of the boot to be determined.
