A sports boot including an upper extending above the ankle joint and at least one rigid collar extending around the wearer's lower leg, the boot including a device for adjusting the volume of the collar to better accommodate the shape of the user's calf. The adjustment device includes a wedge, or collar extension, positioned inside the collar, the wedge being fixed to the collar by means of at least one pivot and by means of a fastening mechanism enabling the relative displacement of the wedge with respect to the collar as well as a deformation of the wedge. The fastening mechanism includes a plate equipped with a cylindrical body having an axis Al and received in a first circular opening provided in the collar and a rivet received in a second circular opening provided in the wedge and received in a third circular opening having an axis A 2 provided in the body, the axis A 2 and the axis A 1 being non-coaxial. The wedge is fixed by means of a first pivot and a second pivot, which are positioned on respective sides of the collar so that an axis Ap 1 of the first pivot and an axis Ap 2 of the second pivot are located on a first, substantially horizontal plane P 1 and so that the fastening mechanism is not fixed on the first plane P 1. |
