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.

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).

The proposed solution relates to a ski or snowshoe binding, to which binding a normal boot is attachable with general attachments which are part of said binding, such as with a strap in a front part of the binding and with a strap arrangement in a back part of the binding. The strap of the front part of the binding is transverse to the binding, adjustable in length and extends in a toe part of the binding under the body or inside the body of the binding. The cross-sectional profiles of the strap of the front part have been made in such a way that as the strap comes out from the body and turns upwards, a first profile portion is, over this distance, in a direction of width at its narrowest substantially in the entire upward turn, after which a second profile portion is widening and thinning towards a third profile portion.

A binding includes a forward base portion that is configured to attach to a top surface of the ski. The binding includes a rearward base portion that is hingedly attached to the forward base portion. The rearward base portion is removably securable to the ski and movable about the forward base portion. The binding includes a forward adjustable boot retention element that includes a pair of lug wings attached to at least one of the forward base portion and the rearward base portion. A width between the lug wings is adjustable. The forward adjustable boot retention element includes a strap attached to the pair of lug wings. The strap is more flexible than the lug wings.

A ski boot frame that is attachable to a soft shell snow boot, for example a snowboard boot, for downhill skiing. The ski boot frame is constructed of multiple rigid materials to provide a user with proper support for downhill skiing. The ski boot frame further includes adjustable toe clip and heel clips for attachment to a standard downhill ski binding. The toe and heel clips are preferably adjustable to fit the frame to a plurality of sizes of ski bindings. The ski boot frame further includes a calf support that provides for a progressive forward resistance critical for downhill skiing.
