A skate includes an inverted groove-shaped base secured to a boot and including front and rear pins; an elongated frame including front and rear sets of a transverse inner groove and a transverse open groove communicating with the transverse inner groove, and a threaded hole on the transverse open groove of the front set wherein either pin is disposed in the transverse inner groove and the elongated frame abuts an underside of the base; and a locking device including a spring biased block member disposed in the transverse open groove of the front set and having two projections at two ends respectively, a screw driven through a positioning member into the threaded hole to fasten the positioning member in the transverse open groove of the front set so that the block member abuts the front pin to block same in an assembled state.

Disclosed is a closure system used in combination in any of a variety of applications including clothing, for example as a footwear lacing system comprising a lace attached to a tightening mechanism. The lace extends through a series of guide members positioned along two opposing footwear closure portions. The lace and guides preferably have low friction surfaces to facilitate sliding of the lace along the guide members so that the lace evenly distributes tension across the footwear member. The tightening mechanism allows incremental adjustment of the tension of the lace. The closure system allows a user to quickly loosen the lace and inhibits unintentional and/or accidental loosing of the lace.

Provided is a heeling apparatus including an inner shell and an outer shell. The outer shell is configured to interlock with the inner shell. In one embodiment, the inner shell includes a plurality of protrusions configured to interlock with receiving apertures in the outer shell. In one embodiment, the inner shell includes a cavity configured to receive a removable bracket. The bracket includes a mounting assembly configured to receive a wheel assembly. The bracket is held in place by the interlocked relationship of the inner shell and the outer shell.

A fastening element for a shoe of a boot comprising a disk-shaped single or multi-part main part, comprising a base side for fastening to the shoe, a cover side lying opposite the base side, and two grooves molded into a casing between the base side and the cover side for receiving and guiding a respective end of a shoelace. The grooves have an entrance angle at which shoelaces are to enter into the fastening element when laced in the pulling direction and an exit angle at which shoelaces are to exit the fastening element when pulled in the pulling direction, and wherein the entrance angle is greater than or equal to the exit angle.

Skating device (1) provided with a plurality of wheels (2a, 2b, 2c, 2d), comprising: an electric motor (3) operatively coupled with at least one wheel (2a) of said plurality of wheels; at least one acceleration sensor (4) operatively coupled with at least one wheel (2a) of said plurality of wheels (2a, 2b, 2c, 2d); at least one speed sensor operatively coupled with at least one wheel (2a) of said plurality of wheels (2a, 2b, 2c, 2d); and at least one control unity adapted to actuate the operations of said electric motor (3) at least when said acceleration sensor (4) detects positive acceleration of said at least one wheel (2a), wherein the amount of electric power supplied by said electric motor to said at least one wheel (2a) is calculated according to the speed measured by said at least one speed sensor (5), at least when said acceleration sensor (4) detects said positive acceleration.

Described is a portable footwear tightener lace replacement (mechanism) for use with an ice skate, sports shoe, work boot, sneaker or other footwear that has eyelets or lace hooks and normally uses laces for tightening. The portable footwear tightener includes an inside strap having a tooth or ribbed top side, an inside strap footwear attachment structure, an outside strap having a ratchet or clasp/buckle mechanism, an outside strap footwear attachment structure. Each of the inside strap and the outside strap is attached to the footwear through the eyelets, hooks or hoops by the inside strap footwear attachment structure and the outside footwear attachment structure, respectively, and the ribbed or toothed portion of the inside strap is connectable to ratchet or clasp/buckle mechanism of the outside strap into a snug arrangement.

A system for analysis of user gait and foot disorder intended to minimize risks ulceration and limb amputation associated with the uncontrolled increase of the foot temperature in persons with diabetes. This system comprises a motion, force and temperature sensors and a processing element configured to process motion algorithms, measure ground reaction force (GRF) and changes in foot temperature embedded in the footwear insoles in communication with a smartphone based analysis application using wireless radio interface. The analysis application processes data received from the footwear sensors, compares the results with set of criteria and rules, and if any of the predefined criteria is exceeded, provides alerts to the user and the remote medical supervisor. Additionally, the insoles may be equipped with a haptic actuators configured to determine the level of the user neuropathy by measuring vibration perception threshold (VPT) level.
