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 apertures formed by omitting stitches and non-textile elements on the lateral side and in the heel area. Various warp or weft knitting processes, including flat knitting, may be utilized to form the textile element.

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 comprise one or more of an inner layer, outer layer, or intermediate layer of the upper. Various warp or weft knitting processes, including flat knitting, may be utilized to form the textile element.

Disclosed are shoes including a body having a foot insertion space into which user's foot is inserted, an air passage portion protruding from a front of the body to the outside and extending in a direction in which the body extends, and a foot support portion located in a width direction of the air passage portion. In addition, shoes according to another feature includes a first body portion in which a portion of a front foot portion of a wearer is positioned, a second body portion connected to the first body portion and in which the other remaining portion of the front foot portion, a middle foot portion, and a rear foot portion of the wearer are positioned, a cover seamlessly connected to the second body portion and protruding in an outward direction from both edge portions, at least one protrusion protruding from an inner surface of the cover and extending in a direction in which the second body portion extends, wherein a protruding thickness of each protrusion decreases from an upper portion toward the first body portion.

A shoe upper includes a mesh covering unit having opposite first and second surfaces and including a plurality offirst and second yarns, and a fabric layer disposed on the second surface. Each of the first yarns has a first core yarn, and a first coating layer wrapped around the first core yarn and made from a thermoplastic material. The first and second yarns are interknitted to form a plurality of holes extending through the first and second surfaces, and to have first portions of the first coating layers and first portions of the second yarns forming the first surface, and second portions of the first coating layers and second portions of the second yarns forming the second surface The first portions of the first coating layers at the first surface are larger in surface area than the second portions of the first coating layers at the second surface.

Systems and devices are described for creating a more effective mechanical ventilation system for footwear. For example, a mechanical ventilation system can include an air reservoir that is almost as large as the entire shoe under the footwear's foot bed. In some examples, the air reservoir can be connected to an area that includes a foot of a user in the footwear. The air reservoir can be compressed using a movable part that circulates air in the footwear with every step. The movable part can be relatively small, extending into the air reservoir, and able to compress and inflate the air reservoir. Movement of the movable part can cause a large effective compressible area of the air reservoir to release fresh air near the toes of a foot to flush stale air out of the footwear.

A ventilation apparatus including at least one flexible energy storage device (FESD), a switching unit, a pump, and a fluid diffuser is provided. The FESD flexibly conforms to varying contours of footwear. The FESD positioned at one or more locations of the footwear supplies electrical energy to the pump via the switching unit. The switching unit in communication with the FESD and the pump selectively changes modes of operation of the pump. The pump attached to the footwear pumps fluid into and exhausts fluid from a cavity of the footwear. A feed pipe of the fluid diffuser connected to the pump, within the cavity of the footwear, transfers the fluid pumped from the pump to the cavity of the footwear during a pump mode and transfers the fluid in the cavity of the footwear to an ambient environment external to the footwear during an exhaust mode for ventilating the footwear.

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. Various warp or weft knitting processes, including circular knitting, may be utilized to form the textile element.

An upper for an article of footwear includes a three-dimensional engineered textile having an inner section, an outer section, and an intermediate section disposed between the inner section and the outer section. The intermediate section is attached to the inner section on one side and the outer section on an opposite side. The intermediate section extends through at least a forefoot region of the upper. In the forefoot region, the intermediate section includes a plurality of curving portions arranged adjacent to each other such that each curving portion of the plurality of curving portions is spaced apart from neighboring curving portions by one or more gaps. Air is configured to flow from an interior of the upper to an exterior of the upper through the one or more gaps between neighboring curving portions of the plurality of curving portions in the forefoot region of the upper.

A shoe insert is configured as a single component with a specifically-configured shape that provides internal shoe structural support while enhancing airflow within the shoe. The shoe insert is comprised of a rigid structure, such as plastic, that engages with the inner and outer sides of the shoe to provide sufficient support. The shoe insert's inner and outer sides, which engage with the shoe's inner and outer sides, have a grip portion with an upper opening substantially positioned at the shoe's ankle opening. This upper opening enables air to flow therethrough and provide breath to the shoe's interior cavity. Airflow holes spread sporadically throughout the shoe insert's body enables air to flow through the shoe insert and engage the shoe to provide breathability, thereby preventing moisture, mold, and stench.
