A suction-preventing footwear includes a boot, a first-vent, a second-vent, a third-vent, a manifold, and a one-way valve. The boot may include a sole having a heel and toe, as well as an upper extending above the sole for covering a user's foot having a vamp, a boot shaft, and a cuff. The first-vent may be affixed to the boot shaft near or on the cuff. The second-vent may be affixed to the top of the vamp, and the third-vent may be affixed to the rear of the boot shaft above the heel of the sole. The manifold may join the first-vent, the second-vent, and the third-vent together, such that each is in fluid communication with the others.

The present disclosure provides a recyclable golf shoe. The golf shoe may comprise an upper comprising a mesh layer and a sole assembly connected to the upper. The sole assembly comprises a first plurality of foam layers in a rearfoot region of the golf shoe, a second plurality of foam layers extending between the rearfoot region of the golf shoe and a forefoot region of the golf shoe, and a support positioned adjacent to the second plurality of foam layers. The second plurality of foam layers is positioned between the first plurality of foam layers and the support. The mesh layer, the first and/or second plurality of foam layers, and the support may comprise one or more recyclable polyethylene terephthalate (PET) materials.

A ventilation apparatus including a pump, a switching unit, and a fluid diffuser is provided. The pump attached to the footwear pumps fluid into and exhausts fluid from a cavity of the footwear. The switching unit in communication with the pump selectively changes modes of operation of the pump. The fluid diffuser connected to the pump within the cavity of the footwear includes a feed pipe for transferring the fluid pumped from the pump to the cavity of the footwear during a pump mode of operation and to transfer the fluid in the cavity of the footwear to an ambient environment external to the footwear during an exhaust mode of operation, for ventilating the footwear. In one or more embodiments, the fluid diffuser includes a diffusing member with one or more openings and/or a fluid distribution channel member for transferring the fluid to and from the cavity of the footwear.

The application provides for a vibrating foot massager that resembles a common shoe. This vibrating foot massager has a number of vibrating motors which can be placed in a variety of combinations within the sole of the shoe. Preferably, the vibrating foot massager will be equipped with a power source so the entire device will be portable. This will enable a user to enjoy the benefits of receiving a foot massage while on the go. The vibrating foot massager is also equipped with a power switch such that when the motors are not in use, the device operates as a functional shoe.

A cycling shoe comprises a sole defining an undersurface of the cycling shoe, the sole having connection holes configured for connection of a pedal cleat to the sole. An upper is connected to the sole and defining with the sole a foot-receiving cavity. An expansion zone is located in a lateral or medial subportion of a metatarsal portion and/or toe portion of the cycling shoe and configured to be opposite a portion of at least a fifth metatarsal of a wearer of the cycling shoe, the expansion zone being entirely surrounded by a window of structural upper panelling and defined by at least one panel having a greater stretching characteristics than the structural upper panelling of the window.

An article of footwear and a method of manufacturing the article of footwear are disclosed. The footwear may include an upper and a sole structure. The upper incorporates a textile element with edges that are joined together to define at least a portion of a void for receiving a foot. The textile element may also have a first area and a second area with a unitary construction with varying stitch configurations. The upper may also incorporate longitudinal ribs extending along the lateral and/or medial sides of the upper. Various warp knitting or weft knitting processes may be utilized to form the textile element.

A shoe has a sole structure (3) and an air pump device for blowing air into the shoe interior space (14). The air pump device comprises a bellows formed in a cavity (10) in a heel area of the sole structure (3), an intake channel coupled to the bellows for transporting air to the bellows from an intake opening, and an air supply device coupled to the bellows for forwarding air from the bellows into the shoe interior space (14). The sole structure (3) has a multilayer structure at least in the heel area, which comprises at least one cover layer (7) with a layer made from a bending stiff material arranged over the cavity (10), at least one intermediate layer (6) of a compressible material that includes the cavity (10), and at least one outsole layer (5) arranged below the cavity (10). The layer of bending stiff material forms a bending stiff plate (8) that overlaps the cavity (10). The cavity (10) has an average height of at least 4 mm and extends horizontally over most of the surface of the heel area, so that a support strip (16) of the compressible material of the at least one intermediate layer (6) remains between the cavity (10) and the outside edges of the sole structure (3) on the sides and at the heel, wherein the support strip (16) extends vertically over the full height of the cavity (10) and the average width of the support strip is not more than 20% of the maximum width of the heel area measured transversely to the walking direction. The compressible material has an average hardness between 30 and 55 Shore-A at least in the area of the support strip (16).

An article of footwear and a method of manufacturing the article of footwear are disclosed. The footwear may include an upper and a sole structure. The upper incorporates a textile element with edges that are joined together to define at least a portion of a void for receiving a foot. The textile element may have a first area with a first knit construction and a second area with a second knit construction.
