A binding for skis and/or splitboard and/or roller skis and/or snowshoes permitting free lifting of the heel, which permits to lift the front part of the foot. The object of the present solution is also an adapter for standard bindings, a method of binding shoes for skis and/or splitboard and/or roller skis and/or snowshoes, and also a shoe for riding skis and/or splitboard and/or roller skis intended for use in bindings permitting free lifting of the heel.

A toe-piece of a ski binding includes rotatable first and second clamping members respectively provided with first and second jaws. First and second rotatable supports rotatably bear the first clamping member and the second clamping member, respectively. In a ski descent configuration, the first and second jaws can elastically retract if solicited by a tip of a ski boot. The first clamping member has a third jaw with a first pin, while the second clamping member has a fourth jaw with a second pin. Locking means are provided which when the ski boot tip is between the third and fourth jaws, the blocking means are activatable to block the third and fourth jaws in angular blocking positions in which the first pin is inserted in a first hole of a ski boot and the second pin is inserted in a second hole of the ski boot, making walking uphill possible.

A binding having a front plate (2), a front assembly (3) for immobilising the boot and capable of cooperating with the sole (81) of the boot (8), a rear assembly (6) for retaining the boot and capable of cooperating with a retaining lug (85) of the rear portion of the front sole and/or with the rear sole, the rear assembly being movable relative to the front plate in the vertical plane, and tensioning means (66) which act between the rear retaining assembly (6) and the ski and/or the front plate (2) and which are capable of tensioning the boot (8) on the binding (1) and enabling the heel to be raised freely. The front immobilisation assembly is mounted in a floating manner on the front plate about a transverse pivot axis (A3), the supporting point enabling the front end (81′) of the sole (81) of the boot.

An apparatus for holding a footwear heel to a snow travel aid is provided. The apparatus comprises a mountable base connected to a generally vertical post and an upper portion having at least one forward connector for connecting the upper portion to the heel. The upper portion is rotatable on the post between a downhill position and at least one touring position and comprises at least one part which travels over a prominence at a fixed location relative to the upper portion during rotation from the downhill position to the touring position. The at least one part becomes engageable with a depression adjacent the prominence when the upper portion is in the touring position to resist rotation from the touring position back to the downhill position. The post comprises a feature that provides clearance for the at least one part to travel over the prominence or which functions as the prominence and depression. Also provided are posts for use as a part in such an apparatus.

A toe piece for a device for fastening a boot on a sliding board, having a base (130; 3) intended to be fixed to the sliding board, two lateral jaws (101; 8, 9), each mounted to be rotationally mobile on the base (130; 3) about a substantially vertical rotation axis (103; 10, 11), so as to occupy a closed position to hold a boot and a separated position to release or receive a boot, and a pusher (110; 35) having two lateral trig surfaces (114; 24, 25) each cooperating with a respective ramp (104; 22, 23) of each jaw (101; 8, 9), this pusher being linked to the base by a trig spring (112; 36), and two links (120; 28, 29) each linked to a jaw by a first lateral axis (123; 14, 15) and linked together by at least one central axis (125; 32).

A heel unit apparatus for a ski touring binding features two separate heel pins projecting forwardly from a heel body, and a heel pin blocker engaging the heel pins at an adjustable location within lengthwise mid regions thereof to laterally restrain outward spreading of the heel pins at said location. A blocker adjustment is operable to vary location of the blocker. Rear regions of the heel pins are restrained against longitudinal and lateral displacement. Lateral outward spreading of the heel pins in front of the heel body during both forced insertion of a footwear heel and safety release thereof is achieved by laterally outward flexure of the heel pins themselves. The adjustable location of the blocker varies the resistance to such spreading, thus setting the effective spring stiffness of the heel unit, and thereby dictating the spreading force needed to spread the heel pins apart during footwear insertion and release.
