The length-adjustable crampon for a shoe includes a connecting element, a first part and a second part connected by the connecting element. The crampon includes means for setting the length of the crampon and a locking device configured to maintain the length setting of the crampon. The crampon is configured so that, when the locking device is in an unlocking configuration, a force exerted on the crampon induces an automatic transition from a coupling configuration of the setting means with the connecting element, ensuring the length setting of the crampon, to an uncoupling configuration of the setting means relative to the connecting element, the force being exerted to adjust the length setting of the crampon by reducing the length of the crampon.

The present disclosure is directed toward a device that can be worn over footwear to provide traction, such as on slick or slippery surfaces, in snow, or on ice.

A crampon for ski mountaineering, mountaineering, or hiking boots includes a frame with front and rear portions connected by a longitudinal connecting rod, wherein the front portion includes retention elements and a support surface with a first coupling seat oriented at an angle relative to the crampon's axis, and the connecting rod includes at least one selector extending along an axis forming an angle with the crampon axis, such that by matching the angles of the selector and the coupling seat, the crampon can be configured for either a ski mountaineering boot or a mountaineering/hiking boot, thereby enabling optimal fit and secure attachment for different boot types.

A fall prevention footwear accessory device includes a first strap configured to wrap around a footwear upper portion and sole at a ball portion of the footwear. A second strap has an attachment end rotatably connected to a first end of the first strap and a cleat region with a plurality of cleats. A first fastener rotatably connects the first strap and the second strap. A second fastener adjusts the length of a loop portion of the first strap around the footwear. The accessory facilitates temporary relocation of the second strap from a first position arranging the cleat region adjacent to the sole of the footwear to a second position arranging the cleat region over the footwear upper portion away from the sole portion.
