A ventilation apparatus for an article of footwear has a hollow air pump chamber, one or more one-way air valves positioned through the top wall of the air pump chamber, and an air intake channel with a one-way valve coupled through an opening into the air pump chamber. Action of stepping down on the air pump chamber deforms the walls and increases pressure in the air pump chamber, and forces air out of the air pump chamber through the one or more one-way air valves positioned through the top wall of the air pump chamber, and action of lifting weight off the air pump chamber causes the deformed walls to return toward original form, decreasing pressure in the air pump chamber and drawing air in through the air intake channel.

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 flat knitting, may be utilized to form the textile element.

The Shoe With Snaps Buttons and Open Hole For Articles has an opening front hole window to keep fresh air on the feet, the feet to breath better, and which may also help the nails not change their color after long periods of shoe wearing, and keep the feet warm. It has four snaps buttons closure. It can be wore in summer when it is hot and in the winter when it is cold or just for fresh air. The shoe closes on both sides. One closes on top leaving a window open. The other closes at the bottom. It has a backslash line design on both side of the shoe. It has forward slash and backslash on the back of the 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 paneling and defined by at least one panel having a greater stretching characteristics than the structural upper paneling of the window.

The invention provides a textile comprising a supporting mechanism disposed on a surface of a fabric, having a printed layer and a layered elastic support; the elastic support is made of thermoplastic elastomer, and is connected with the printed layer; and a plurality of air-permeable elements disposed in the supporting mechanism. The textile of the invention can be made into wearables for a human body, and the supporting mechanism is capable of supporting human motor organs. The invention also provides a supportive thermoprinting material, a printed layer and a thermoplastic elastomer material layer are disposed on a surface of a substrate, and the printed layer and the thermoplastic elastomer material layer of the thermoprinting material are combined on a fabric to form the textile of the invention.

Exemplary embodiments of the present disclosure are directed towards a self-ventilating footwear assembly comprising: one or more cylindrical and barrel shaped profile structures includes one or more spore structures, the one or more spore structures is configured to provide ventilation and protection to the foot of the wearer, and one or more conical shape profile structures integrating with the one or more cylindrical and barrel shaped profile structures and which is configured to connect an outer surface of a shoe vamp. The self-ventilating footwear assembly further comprising a hollow portion of the interior structure configured to allow the air passed through the one or more conical shape profile structures for providing both superior ventilation and protection to the foot of the wearer, and the specialized structures is configured to provide physical protection and shock absorption against object striking the top and sides of the wearer's foot.

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 disposable, low friction, breathable bootie is provided that accommodates the shape and size of a human foot. The bootie is made from a thin, flexible polymer sheet-like material in a generally tubular form. The bootie has a foot portion, a lower leg portion, and an ankle portion therebetween. The bootie includes a series of air vents in the foot portion and lower leg portion to provide airflow to the foot, while such vents are located to avoid key friction points between the foot and the ski boot during the donning and doffing processes. The bootie facilitates donning and doffing a ski boot. The vents provide breathability while the bootie is worn within the ski boot.
