A ski boot (1) includes an inner boot (1.1) that is designed to accommodate the skiers foot and a leading shell (1.2) that surrounds the inner boot (1.1), making it possible to hold the skiers ankle in place. This boot (1) also includes a calf support (3) attached to the shell (1.2) that is designed to accommodate the skiers calf, and a thigh support (5) that forms an angle (&alpha) with the calf support (3) that is designed to accommodate the skiers thigh when the latter is in the bent position. Preferably, the boot includes a damping element (8, 23, 27) that is installed between the calf support (3) and the thigh support (5), as well as elements (25, 26) for adjusting the angle (&alpha) between the calf support (3) and the thigh support (5).
