An upper for a sports shoe may include a component such as a vamp or a rear portion. The shoe component may include a UV curable microlattice structure with a plurality of regions such that each region has a different density. In some cases, the microlattice structure may include a high density microlattice structure, a mid-level density microlattice structure, and a non-structural region with a low density microlattice structure.

A running shoe can include a sole and an upper formed separately from and connected to the sole. The sole can include a toe cap connected to a toe portion of the sole, at least one drainage hole positioned at and extending through the toe cap, a drainage hole cover including a flexible water permeable material extending over and visually obscuring the at least one drainage hole, the drainage hole cover extends over an area of the toe cap adjacent to and surrounding the drainage holes, and a foot cavity defined at least in part by an interior surface of the upper.

A medical shoe having an overmolding layer with a non-uniform density is provided. The medical shoe may include a midsole configured to support a foot, and a frame surrounding the midsole. The midsole may include a foot receiving portion forming a substantially planar surface for supporting the foot and a frame receiving portion opposite the foot receiving portion. The frame may include an overmolding layer extending from a side of the frame opposite the midsole so as to form a ground contacting surface. The overmolding layer may have a non-uniform density. The sole assembly may be secured to the frame by a self-locking fit between the sole assembly and the frame.

A medical shoe having a plurality of outsole projections is provided. The medical shoe may include a sole assembly configured to support a foot, and a frame surrounding the sole assembly. The sole assembly may include a midsole portion forming a substantially planar surface for supporting the foot and an outsole portion including the plurality of outsole projections extending from the midsole portion. The frame may include a plurality of through holes corresponding to the plurality of outsole projections. The plurality of outsole projections may extend through the plurality of through holes so as to form a ground contacting surface. The plurality of outsole projections may also be provided in a symmetrical pattern. The sole assembly may be secured to the frame by a self-locking fit between the sole assembly and the frame.

Articles of footwear, including athletic footwear, include one or more of: (a) a sole structure; (b) an upper having lateral and medial side elements engaged with the sole structure, the upper made from a polymer matrix structure that extends through at least a heel region; (c) a size adjustment mechanism located at the heel region; (d) a heel tongue element located adjacent the size adjustment mechanism; (e) a shoe securing mechanism; (f) an instep tongue member; and/or (g) a bootie member located at least partially within the foot-receiving chamber. Methods of manufacturing such articles of footwear also are disclosed.

Shoes, in particular sports shoes, and methods for their manufacture can correspond to a shoe that has an upper with a textile region in at least one of a forefoot region and a midfoot region, as well as a heel cap of the upper. The heel cap substantially surrounds a rear side, a medial side, and a lateral side of a heel of a wearer's foot when worn. The heel cap forms a heel region of the upper, and the heel cap is manufactured substantially as one piece from a non-textile flexible plastic material.

An airbag device includes a wear and an elastic module mounted on the wear. The wear has a wearing space. The elastic module is mounted in the wearing space of the wear and includes a first air bag, a second air bag, a first control valve and a second control valve. The first control valve is connected with the first air bag and is provided with a first oneway air inlet and a first oneway air outlet. The second control valve is connected between the first air bag and the second air bag and is provided with a second oneway air inlet and a second oneway air outlet. The second control valve and the first control valve are operated synchronously.

A shoe (2) having an air-permeable tongue, according to the present invention, comprises: a tongue outer cover (131) having a plurality of vent holes (135); a tongue inner cover (133) provided under the tongue outer cover (131); and a spacer structure (132) having a main body part (132b) fitted between the tongue outer cover (131) and the tongue inner cover (133), and a wing part (132a) extending from the main body part (132b) toward the front of the shoe so as to be positioned under a vamp (140), which is an upper forming the front portion of the shoe. The spacer structure (132) comprises: an air-permeable part (132-1) upwardly formed from the wing part (132a); an air-permeable part (132-3) downwardly formed from the main body part (132b); and a space passage (132-2) formed in the wing part (132a) and the main body part (132b) so as to enable air to pass between the wing part (132a) and the main body part (132b). According to the present invention, heat or smell, which is generated at the front portion of the shoe, naturally passes through the space passage of the spacer structure and is discharged to the outside through the vent holes of the tongue.

An article of footwear including a sole and an upper with an exterior and interior surface, and one or more bladders which comprises at least one of the exterior or interior surfaces of the upper. The bladder comprising sheets of polyurethane or polyester film attached together to form an airtight seal. The article of footwear also includes a inflation mechanism for selectively introducing air in the one or more bladders. The inflation mechanism is located under the foot of the wearer to be activated by the normal action of the wearer to inflate the one or more bladders. The article of footwear may also include an assembly for connecting several tubes to one under foot inflation mechanism. The article of footwear may also include inflatable laces that are inflated by an underfoot inflation mechanism.
