In a first aspect, a wearable device is provided for mounting to a foot of a user. The wearable device includes a support structure having a longitudinal axis, and having an interior. The support structure is positioned to support a foot of a user, wherein the support structure has a ground engagement surface. The wearable device further includes a first wheel shaft having a first wheel connected thereto, and a second wheel shaft having a second wheel connected thereto. The first and second wheel shafts are connected to the support structure and are movable between a stowage position in which the first and second wheel shafts hold the first and second wheels above the ground engagement surface and a rolling position in which the first and second wheel shaft hold the first and second wheels below the ground engagement surface. In both the stowage and rolling positions, the first and second wheels are laterally outside of the interior of the support structure.

The inventive subject matter shown and described is directed to an item of footwear with a tensioning system, comprising: a shell for enclosing a foot and at least a portion of a lower leg; a pair of opposing edges generally aligned along the top of foot portion of the shell and/or a front lower leg portion, the edges generally aligning with a longitudinal axis of the foot and/or lower leg, the opposing edges defining opposite sides of the shell.

A skate includes a skate boot and wheel assembly; an outer seat disposed on the skate boot and wheel assembly; an inner seat disposed in the outer seat; a tongue disposed on the inner seat; a cover disposed on the tongue; a first hole disposed in a toe portion of the outer seat; a second hole disposed in front of the first hole; a biasing member disposed in both the first and second holes; two projections having a through hole disposed on a front end of the cover; and a pivot disposed through the through holes and the biasing member to assemble the cover and the outer seat. Thus, the tongue is pivotal.

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.

A hard-shell boot comprises a boot liner and an outer shell having an accommodation space for accommodating and positioning the boot liner. Two sides of a top portion of the outer shell respectively have a first flank portion vertically penetrated by a first-through-hole and a second flank portion vertically penetrated by a second-through-hole. A connecting member comprises an inner-blocking-piece located in an inner side of the top portion of the outer shell and an outer-blocking-piece. One end and the other end of the inner-blocking-piece respectively have a first-engaging-portion connected to one end of the outer-blocking-piece by passing upward through the first-through-hole and a second-engaging-portion connected to the other end of the outer-blocking-piece by passing upward through the second-through-hole. Thus, the width and size of the hard-shell boot can be adjusted simultaneously to facilitate the use of users with different foot widths and sizes.

A hard-shell boot comprises a boot-liner and an outer-shell having an accommodation-space for accommodating and positioning the boot-liner, the boot-liner has a sole which comprises a first-elastic-sheet and a rear-bottom-sheet on the same level, the rear-bottom-sheet is jointed to a rear side of the first-elastic-sheet; an outer periphery of the sole is extended upward to form an upright-portion which comprises a second-elastic-sheet and a rear-upright-sheet, two ends of a rear side of the second-elastic-sheet are jointed to two ends of a front side of the rear-upright-sheet respectively, an outer periphery of a top portion of the upright-portion is extended upward to form a sleeve-portion, a front end of the sleeve-portion has a third-elastic-sheet; thus, it is capable of being adjusted according to the width and size of the user's foot simultaneously, so as to facilitate the use of users with different foot lengths and sizes.

Systems and methods are described for providing coaching, training, or equipment specification information to individual golfers based on data generated during their individual golf swings. Additionally, data hubs are described that provide information and services to individuals based on data collected for a community of multiple golfers. Such community data hub systems and methods may provide one or more of the following: (a) storage of scoring data, swing data, ball flight data, and/or equipment data for multiple golfers; (b) at least some level of individual access to the stored data for the community; and/or (c) electronic interaction between golfers within the community.
