Coupling assembly between a footwear and a sport equipment comprising at least one housing on the footwear near the sole suitable for receiving a first metallic element, a binding, on the sport equipment, provided with a seat for the insertion of the footwear, the binding being equipped with at least a second metallic element positioned in the seat, the first or the second metal element being an electromagnet, which when activated is magnetically bound to the other element.

A combination of a ski boot and a strap where the strap extends from an attachment point on the lateral side of a hard outer shell of the boot and in use is tightened to hold the inner boot liner in relatively fixed proximity to the lateral side of the outer boot shell during skiing. The strap can extend around the inner boot liner, or be at least partially incorporated as a part of the inner boot liner. In either case, the strap is adjustable between the tightened position, and an open position.

In one example, a ski boot includes a plastic shell, a boot liner partly received within the plastic shell, and the boot liner including a tongue having an upper edge, and a dynamic support strap. The dynamic support strap includes a band connected to the plastic shell, and a restraint element connected to the band, the restraint element including a wall and a lip that together define an undercut area behind the wall, and the undercut area is configured and arranged to receive a portion of the upper edge of the tongue when the restraint element is operably positioned with respect to the tongue.

An article of footwear with adjustable stiffness is provided. The article of footwear in the form of a snowboard boot is provided with adjustable tensioning systems that are disposed on either side of an inner liner of the snowboard boot. The adjustable tensioning system includes a comb body structure having flex portions made of a plurality of extending fingers with a flexibility that can be controlled by the adjustable tensioning system. Depending on the level of tension applied by the tensioning system, or lack thereof, a range of flex profiles having varying amounts of stiffness are available to the wearer to adjust the overall stiffness of the snowboard boot.

An apparatus for charge-assisted release of a ski binding includes an explosive material, a battery, an electrical circuit, and a processor. The explosive material is mounted on or in a ski, a ski boot, and/or a ski binding. The apparatus also includes The electrical circuit extends from the explosive material to the battery, the electrical circuit including a switch having a connected state in which the battery and the explosive material are electrically connected through the switch and a disconnected state in which the battery and the explosive material are electrically disconnected. The processor is electrically coupled to the switch and configured to generate an output signal that transitions the switch from the disconnected state to the connected state in response to an input signal from one or more sensors.

A shoe with spikes is disclosed. The shoe includes an accommodation seat, at least one moving plate, a transmission module, a plurality of posts, a plurality of spikes, and a shoe plate. The accommodation seat includes a chamber. The moving plate is disposed in the chamber and controlled to move between a first position and a second position, and includes a plurality of push members. The transmission module is configured to move the moving plate. The posts extend from the accommodation seat toward the ground. The spikes are fixed to the posts and extend out of the chamber. When the moving plate is in the first position, the spikes protrude out of the shoe plate relative to the ground. When the moving plate is moved to the second position, the push members push the shoe plate, and the spikes do not protrude out of the shoe plate.

Coupling assembly between a footwear and a sport equipment comprising at least one housing on the footwear near the sole suitable for receiving a first metallic element, a binding, on the sport equipment, provided with a seat for the insertion of the footwear, the binding being equipped with at least a second metallic element positioned in the seat, the first or the second metal element being an electromagnet, which when activated is magnetically bound to the other element.

A sports shoe has a lower boot portion to receive the user's foot and an upper boot portion to receive the user's lower leg. In the process, at least one first sensor in a front foot portion of the sole assembly is connected with at least one second sensor in a heel portion of the sole assembly via a multipolar flexible flat cable having an adjustable length as needed, such that a distance between the at least one first and second sensors can be adjusted to various sole lengths during the manufacturing of the sports shoe. This can be specified correspondingly for at least one third or fourth sensor in the upper boot portion and the at least one first or second sensor on the sole assembly of the sports shoe, such that an adjustment to the upper boot portion with various model-dependent height dimensions is facilitated during manufacturing.

A shoe with spikes is disclosed. The shoe includes an accommodation seat, at least one moving plate, a transmission module, a plurality of posts, a plurality of spikes, and a shoe plate. The accommodation seat includes a chamber. The moving plate is disposed in the chamber and controlled to move between a first position and a second position, and includes a plurality of push members. The transmission module is configured to move the moving plate. The posts extend from the accommodation seat toward the ground. The spikes are fixed to the posts and extend out of the chamber. When the moving plate is in the first position, the spikes protrude out of the shoe plate relative to the ground. When the moving plate is moved to the second position, the push members push the shoe plate, and the spikes do not protrude out of the shoe plate.

A sport-boot pressure monitoring system and method of use. The system includes a left boot sensor having a left flexible fluid-containing bladder shaped to fit between a user's left leg and an interior surface of a left boot worn by the user and a left pressure sense element in pressure-sensing communication with the left flexible fluid-containing bladder, a right boot sensor that is similar to the left one, and a controller to provide a pressure alert if pressure between one of the user's legs and the interior surface of the boot worn on that leg violates a predetermined pressure threshold and to provide a proximity alert if a distance between the left and right boots violates a predetermined proximity threshold.
