A device attachable to a pair of cross-country skis for grooming a trail in fresh snow simply by skiing the first pass. The purpose of this invention is to create a grooved trail in fresh snow to guide all skiers that follow in the same track. Without this attachment installed on the lead skier's ski, the soft snow on each side of the packed ski track does not help to keep the subsequent skier's ski in the lead skier's track. For them, it is like trying to ski on top of a narrow rail. This creates a situation where the skier must be diligent to stay in the track. With this device installed on the lead skiers ski, the subsequent skiers are guided by the packed snow on the sides of the lead skier's ski track. When skiing in tracks made using this invention, a skier can ski faster and smoother than in untracked snow. Since the compacted track helps guide the skier in the track, it allows the skier to focus on, and enjoy, the surroundings scenery. Another unique characteristic of this invention is its 2-part construction that allows the trail-making portion of the invention to be added and/or removed at any time. This allows the skier to easily change from being the lead skier to being a following skier. Or, if skiing alone, to return without the trail-making attachment, along the track he or she previously made.

Apparatus and methods are disclosed for positionally stabilizing snowsport equipment such as snowboards while in use on snow or ice. The apparatus includes a position establishing unit having an interface and a guide situated in an angular relation to one another and a tether connectable between the establishing unit and either the equipment or an article associated with the user.

A fastening assembly for a ski crampon includes a hinge pin having a mounting portion and a securing portion. The mounting portion has a smaller dimension in a first direction and a larger dimension in a second direction, the first and second directions orthogonal to the longitudinal direction of the hinge pin. The securing portion has substantially the same dimension in the first and second directions. A mounting fastening portion defines a gap and an opening. The gap and the opening each extends substantially transversely to a ski longitudinal direction and substantially parallel to the ski surface. The gap receives the mounting portion of the hinge pin, which is inserted through the opening. The dimension of the opening in the ski longitudinal direction is larger than the dimension of the mounting portion in the first direction and smaller than the dimension of the mounting portion in the second direction.

A sporting equipment is disclosed. The sporting equipment may include a harness, and a protective plate. The protective plate may be integrally formed with the harness from a plurality of fibers that are continuous from the harness into the protective plate.

A system for analysis of use of a sliding board comprising at least one piezoelectric element configured to be secured to the sliding board and generate electric energy during deformations of the sliding board; and an electronic processing circuit configured for estimating at least one parameter of use of the sliding board and configured to be connected to the sliding board. The electronic processing circuit is powered by the electric energy generated by the at least one piezoelectric element.

A system for analysis of user gait and to provide correction in form of haptic and visual feedback. This system comprises a motion and force sensors and a haptic actuator embedded in the user shoe insoles in communication with a smart-phone based analysis application, configured to calculate motion and orientation of the user feet in relation to the value, location and distribution of ground reaction forces measured by sensors located in the shoe insoles and after analysis of said forces and motion, to provide haptic feedback to the user foot instructing about the location (and timing) of pressure the user must apply to achieve an optimal gait.

Some embodiments are directed to an analysis device for board sports, intended to be secured to a board, such as a surfboard or ski, at the interface with the user. The device includes: a force sensor designed to capture one or more forces generated by the user on the board; a position and motion sensor designed to capture the position, speed and acceleration of the board in space; and a processing unit or processor connected to the force sensor and to the position and motion sensor and designed to synchronize and process the data from the sensors.

A pole handle having a fastening mechanism for a hand strap with loop strips at variable lengths with a clamping element mounted in a recess. The recess is a through-opening of which the lower opening opens within a rear handle region, and the upper opening towards the upper side of the handle. The clamping element has a lever arranged in the through-opening and a head region projecting upwards out of the recess and has a loop opening and a pressure-exerting surface. The loop strips are guided through the through-opening, past the lever, and through a loop opening of the clamping element, the free ends of the loop strips exiting at the top. The clamping element can be secured in a clamping position in which the loop strips are clamped in a releasable manner, and the clamping action can be released by the clamping element being tilted around a rotary pin.
