According to one embodiment, a removable tightening device is described. The tensioning mechanism is removably coupleable with an article without damaging the article so that upon removal, the coupling of the tensioning mechanism with the article is unrecognizable or not readily detectable. The tensioning mechanism is operable with a tension member to maintain a tension of the tension member and thereby maintain a tightness of the article. The tension member is guided along a path about the article, via one or more guide members, and is tensionable, via the tensioning mechanism, to tighten the article.

Equipment that includes a shoe/footwear and a range of footwear elements, and a method of using such equipment, each of such elements being configured to enable a user to perform a type of physical activity that is different from the types of physical activity enabled by the other footwear elements in the range of footwear elements.

The technology disclosed herein includes a dual-molded layer overshoe apparatus comprising a cleat, a sole layer configured to receive the cleat, and an upper layer, wherein the upper is molded to the sole layer and the upper layer has a lower durometer than the sole layer, and wherein the plurality of pin plates are secured between the sole layer and the upper layer. Significant elasticity in the upper layer allows stretch for installation and removal. Reduced elasticity in the sole layer offers greater durability in terms of spike retention and abrasion resistance. In one implementation, the components are assembled in one contiguous, fixed arrangement, wherein the cleat is molded into the sole layer, and the upper layer is then molded to the sole layer.

Spats comprise: a body, one end and the other end of which are attached to or detached from each other; an elastic line extending from the one end to the other end inside of the lower side of the body; and one or more hooks connected to the elastic line and exposed to the outside.

A nonskid spike structure is molded with the sole of a snowshoe or particular nonskid shoe, mainly comprising a large top end plate on the top edge of a metal spike body at the sole face and a middle plate with a smaller diameter spaced apart therefrom and positioned below the lower edge thereof, thereby forming a double-layer top edge. A central spike rod is extended downward with a convex spike head rod from the bottom thereof, allowing it to be inserted in a mold directly and integrated with the rubber sole upon molding, achieving the simple positioning in the mold and molding without deflection upon pressing, thereby allowing sole rubber material to cover the spike body directly. Whereby, the spike will not take off through the stable combination of the double plate edge and sole material, achieving the nonskid and safe effect upon the treading of the spikes on an icy surface.

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.
