The invention relates to a combination of a downhill binding or downhill ski binding, in particular a front jaw of the downhill binding, and a ski boot. The ski boot (10) comprises a rigid ski boot shell (11) and a sole (1) of the ski boot comprising a front end (1b) of the sole, a rear end of the sole, an upper side (1a) of the sole and a lower side (1c) of the sole. The downhill binding comprises a front jaw (20) and a rear jaw, wherein the downhill binding comprises a bearing structure (2) for the sole (1) of the ski boot. The bearing structure (2) has an apex (5) which has a distance (X1), in the longitudinal direction (X), from the front end (1b) of the sole held in the downhill binding of at least 28 mm and at most 34 mm, and wherein the apex (5) exhibits a perpendicular distance (Y2) from the upper side (1a) of the sole of the ski boot held in the downhill binding of 19 mm±2 mm in at least one point.

A toe-piece for binding a boot on a gliding board, the toe piece including a chassis having a lower surface configured to be affixed to the gliding board; a body movably mounted on the chassis; a sole-clamp movably mounted on the body and capable of coming into contact with an upper surface and at least one lateral portion of a front or rear portion of the boot when the boot is engaged with the toe-piece; a lateral release mechanism including at least one first elastic mechanism acting on the sole-clamp to return it to a configuration of engagement with the boot; a vertical retention mechanism comprising a second elastic mechanism, distinct from the first elastic mechanism, arranged so as to continuously exert a return force on the body in order to bring the sole-clamp back toward the lower surface of the chassis, the return force producing a force pressing the sole-clamp on the boot when the boot is engaged with the binding; wherein the toe-piece includes at least one cam kinematically inserted between the second elastic mechanism and either the chassis or the body, the cam being shaped to modify, depending on the position of the body in relation to the chassis, the direction of the return force exerted by the second elastic mechanism on the body so as to attenuate a variation in the pressing force when the sole-clamp is away from the lower surface of the chassis.

A front jaw for a touring ski binding, includes a base and at least one recess or transit opening in the base. Lateral sole retainers lie opposite each other in relation to a longitudinal axis of the front jaw each include a boot retainer pin and, in a pivoted-in state, co-operate with bearings formed on a ski boot, defining a pivoting axis for the boot extending substantially transverse to the longitudinal axis of the front jaw, and are adjustable between the pivoted-in state, where the bearings of the boot engage the boot retainer pins, and a pivoted-away state where the bearings of the boot are not engaged with the boot retainer pins; spring elements for tensioning the lateral sole retainers; a tensioning lever for moving the sole retainers from the pivoted-in state to the pivoted-away state to release the ski boot from a downhill skiing position or a walking position.
