Abstract: An article of footwear including a length adjustment mechanism is disclosed. The article of footwear can include a sole portion with one or more anchors connected to the sole portion. The article of footwear can also include a heel cup capable of moving between a fore position and an aft position. This can be accomplished using one or more length adjustment mechanisms that each slidably engage the one or more anchors, such that they have an unlocked state and a locked state. In the unlocked state, the heel cup can move with respect to the one or more anchors; and in the locked state cannot move with respect to the one of more anchors.

Abstract: An article of footwear having an adjustable width is disclosed. The article of footwear can include a lower sole and an upper sole. The lower and upper soles can have grooves to allow for expansion and contraction. The article of footwear can also include a width adjustment assembly. The width adjustment assembly can have a lead screw, an adjustment device accessible to a wearer from the outside of the article of footwear, an actuation strap, an anchor plate connected to the actuation strap. Rotation of the adjustment device can cause the lead screw to rotate, which in turn can change the tension in the actuation strap. Changes to the tension in the actuation strap can cause the width of the forefoot portion of an article of footwear to be adjusted.

Abstract: An adjustable golf club is disclosed. The adjustable golf club can include a club head having a sole. The sole of the club head may have two or more tracks located thereon. Each track can be configured to receive at least one weight. The two or more tracks may be three tracks.

Abstract: An adjustable golf club is disclosed. The club can be adjusted by moving one or more sliders located proximate the heel of the club. The sliders can move to enable the loft and lie of the club to be adjusted independently. To adjust the club, a user can loosen a fastener, reposition the sliders, and re-tighten the fastener. The one or more sliders can slide against a spherical surface with its origin at the center of rotation of the shaft. In this configuration, when the sliders are pressed against the spherical surface, the spherical surface can enable the club to remain properly adjusted.

Abstract: A softball or baseball bat with modified restitution characteristics is provided. The bat can comprise a substantially rigid shell coupled with a single or multi-piece insert. The shell can comprise a tip end, a barrel, a handle taper, and a handle. The insert can be press-fit or adhered to the inside of the barrel of the shell. The insert can be a single or multi-piece design and can be single or multi-layered. The insert can comprise a material capable of impact absorption. Portions of the insert can be separated from the shell with a separation layer to improve restitution in certain areas of the bat. The insert can also comprise multiple layers that are separated from each other with a separation layer to improve restitution in certain areas of the bat. The material and thickness of the insert and the shell can be varied to meet applicable restitution requirements.

A glove can have one or more protective inserts. The glove can have only one protective insert to protect a user's thumb, or can have multiple inserts to protect the thumb and one or more fingers.

Abstract: A softball or baseball bat comprising a plurality of strips of wood assembled to form a solid material is disclosed. The bat can comprise bamboo, or other suitable material, that provides the necessary hardness, while using a more economical and renewable resource than conventional hardwoods. The plurality of strips can be assembled to form a solid block, which can be shaped into a bat blank. Then blank can comprise a handle portion, a transition portion, and a barrel portion. The bat can further comprise a reinforcing sleeve disposed proximate the handle portion and the transition portion. The finished bat can further comprise a protective and decorative coating.
