The present invention discloses a string adjuster that can adjust the length of a string by winding the string. A string adjuster of the present invention includes a fixed unit and a rotation unit, in which a knob of the rotation unit includes a first extension having a counter-anti-separator formed on the interior circumferential surface and preventing separation from a housing, a second extension having a winding determination protrusion formed on the interior circumferential surface and determining winding and releasing modes, and a spacing groove formed between the first extension and the second extension.

A sports boot having a rigid shell base designed to hold the foot of a user, the shell base including a sole and two lateral sides extending from the sole and defining an upper recess therebetween. The boot includes a mechanism for tightening the shell base around the foot of the user, the tightening mechanism including a filiform element for tightening the sides towards one another, the filiform element being tightened by pivoting a lever of the mechanism. The lever is provided to be pivoted in a notch of a rack designed to cover the two sides of the shell base in the tightened configuration and to bend the sides towards the sole under the pivoting action of the lever. The rack extends across the upper recess E2.

Various mechanical closure systems and securing systems are disclosed, such as snowboard bindings and car rack systems. The systems include a mechanically reformable strap. The strap includes a wire disposed along a longitudinal axis of the strap. The wire maintains the strap in a desired geometry that is different from a previous geometry of the strap. In other embodiments, a wire-core strap can include transverse ridges, holes, or other types of grooves or apertures.

A length-adjustable shoe, of which a length between a front end and a rear end thereof is adjustable, includes an outsole, an upper, a stretch fabric, and a control device. The upper includes a body portion and a heel portion which are mutually separated, wherein the body portion is directly attached on the outsole, and the stretch fabric connects a bottom edge of the heel portion and the outsole. The control device connects the body portion and the heel portion, wherein the control device moves the heel portion relative to the body portion as a whole in an axial direction from the front end to the rear end, which changes the length of the shoe.

A buckle includes a base and a grip lug. The base underside can be placed against and fastened to a boot shell. The base upper side has at least one first receiving extension. In an engagement position a swivel element on the lug is latched at least in certain regions in the first receiving extension to form a swivelable first latching connection, to permit swiveling the lug in the engagement position from an open into a closed engagement position by the swivel element. At least one first latching extension is on the base upper side, and the lug has at least one latching element corresponding thereto. In the closed position, the latching element is latched at least in certain regions on the first latching extension to form a releasable second latching connection, to secure the lug against leaving the engagement position and against swiveling into the open position.

A securing device for attaching hockey skates to a foot. The device includes a series of fastening mechanisms distributed about the shoe along the length of the tongue. The series of fastening mechanisms provides protection and mobility for the foot. Each fastening mechanism includes a buckle, a receiving lip, an insertion lip, a pivot plate, a mounting plate, and an engagement strip. The mounting plate and the engagement strip are integrated into the shoe. The buckle is attached to the mounting plate through the pivot plate and includes a top surface, a bottom surface, a first cavity, a first plurality of teeth, and a locking hook. The buckle may be affixed to the engagement strip through the engagement of the first plurality of teeth and the engagement strip. The buckle may be secured into a locked configuration with the positioning of the locking hook into the keeper indentation.
