The locking device (10) for immobilizing a hinge between a shell (2) and a cuff (3) of a sports shoe (1) includes an immobilizing element (22) mobile between an immobilizing position and a release position, and a blade (12) intended to cooperate with the immobilizing element to immobilize the hinge when the immobilizing element is in the immobilizing position, the immobilizing element including a first guide surface (53) and the blade including a second guide surface (54), the first guide surface cooperating with the second guide surface to guide movement of the blade relative to the immobilizing element when the immobilizing element is in the release position and the cuff pivots relative to the shell.

The present invention relates to a ski shoe tongue assembly (1) with an outer side for arranging against an inner side of a ski shoe (19) and an inner side for arranging against a leg for the purpose ofproviding a filled space between the ski shoe (19) and the leg, comprising: a buffer body (21, 2, 38) for providing a buffer between an inner side of a ski shoe (19) and a lower leg, having on the front side an outer surface which is curved during use for. lying against the inner side of, the ski shoe (19), wherein the buffer body (21, 2, 38) is arranged during use in front of the front side of the leg and in top view extends over a part of the front side of the leg, andthe buffer body (21, 2, 38) comprising, a substantially flat tibia contact surface (4) on the inner side substantially, providing congruence with a tibia for the purpose of making contact with a surface of the leg formed by the tibia of the lower leg.

An apparatus for automatically adjusting tension on retention member to hold multiple objects together. Examples include using retention apparatus to obtain optimal fit and use of a human wearable item such as article of footwear. Sensors may be used to sense changes in movement of the article of footwear, of the person wearing it, or of a third object such as a vehicle carrying the person. A retention member may surround at least a portion of the objects, and an actuator may be included that automatically rotates a rotating member such as a gear or pulley that may be coupled to the retention member. The rotating member may be configured to automatically adjust tension on the retention member many times per second based on control signals from control logic responsive to the sensors.

In one example, a ski boot dynamic support strap includes a band configured to be connected to a ski boot, and a restraint element configured to be connected to the band. The restraint element includes a wall having an upper edge, and a lip that is connected to the upper edge of the wall and extends away from the wall. The lip and the wall collectively form an engagement portion that includes an undercut area, and the engagement portion is sized and configured to accommodate a portion of an upper edge of a tongue of a ski boot liner in the undercut area.

A low friction boot insert 1 that is positioned around the lower leg surrounding a sock 2 and on the inside of a boot 4 such as those worn for skiing. Rotational movement 5 and longitudinal movement 6 of the skin 3 relative to the boot surface is minimised by reducing friction at the interface of the insert and boot or the interface of the insert and sock or both. The reduction in friction transferred to the interface between sock and skin helps to reduce the chafing of the skin which can cause blisters or sores.

A differentially tightenable ski boot includes a lower shell and an upper cuff that is pivotally coupled with the lower shell. The ski boot includes a first tightening system that is coupled with the lower shell and a second tightening system that is coupled with the upper cuff. Each tightening system includes a reel based closure device, a tension member that is operably coupled with the reel based closure device, and at least one guide member that routes or directs the tension member along a path about the lower shell or upper cuff. The first tightening system and the second tightening system are operable independently of each other to independently and differentially tightening the lower shell and the upper cuff.
