Shoe having a transversal air passageway comprising a shoe sole (4) and an upper (1) and a lower (3) pliable parts for enclosing a foot of the user of the shoe, wherein the shoe further comprises a peripheral band (2) formed in the shape of a closed line and formed in a resilient material, wherein the upper and lower parts are attached by their outer edges to opposing faces of said peripheral band along its length, and wherein the lower part is attached to the shoe sole in both the front and back parts of the shoe, but not in a part between the front and back parts of the shoe, such that a transversal air passageway (5) is formed from the medial part to the lateral part of the shoe, between the front and the back parts of the shoe, and between the shoe sole and the lower part.

A method of forming a traced element is disclosed. The method may include printing layers of a traced element and incorporating a textile strand in overlapping polymer layers of the traced element. In some embodiments, the traced element may be formed on a base layer. The traced element may be incorporated into an upper for an article of footwear.

An article of footwear has an upper with multiple components. The upper includes a fastening system, a shield, and a tongue. The shield and the tongue are each attached to the upper. The shield and the tongue may be readily moved to facilitate entry of a foot into the article of footwear, or exit of a foot from the article of footwear.

Swim footwear having integral flippers and sound generators includes a first shoe comprising a sole that is pliable. A compartment is positioned in an interior space defined by the sole. An orifice, positioned in the sole, is fluidically connected to the compartment. A noisemaker is coupled to the sole within the orifice, such that air passing from the compartment through the noisemaker generates a sound. A shell that is coupled to the sole has an entry proximate to a back end of the sole. The shell and the sole define a cavity that is complimentary to the foot of the user. The entry is configured for insertion of the user's foot. A flipper extends from a front end of the sole. The flipper is in substantial parallelism with the sole. The footwear comprises a second shoe that mirrors the first shoe.

An upper including: a plurality of panels provided in a medial side portion and/or a lateral side portion, the panels being separated from one another in a longitudinal direction of a foot, covering at least a portion of the side surface of the foot, and being pulled by a fastening member toward a center portion between the medial side and the lateral side of the foot; and a plurality of string-like non-stretchable string portions that are extending in the longitudinal direction, the string portions placed between a pair of the plurality of panels that are adjacent to each other in the longitudinal direction.

A shoe sole, to which an upper member is joined, the shoe sole including a bottom receiving part corresponding to a bottom of the upper member, and a rising part that is formed to rise upwardly from an upper side of the bottom receiving part so as to cover an outer surface of a side of the upper member, wherein the bottom receiving part is formed with vent grooves each recessed in a thickness direction from the upper surface of the bottom receiving part, wherein the rising part is formed with vent holes each penetrating therethrough in a thickness direction of the rising part, and wherein the vent hole is formed to have a vertically elongated shape extending from an upper end side to a lower end side of the rising part, and to be in communication with the vent groove.

A water-vapor permeable shoe-sole combination (15) with an upper side (5) having at least on through hole (31) extending through the thickness of the shoe-sole combination, a barrier unit (35) with an upper side forming at least part of the upper side (50) of the shoe-sole combination, made of a water-vapor permeable barrier material (33) that forms a barrier against penetration of foreign bodies, by means of which the at least one through hole (31) is closed in a water-vapor permeable manner, a reinforcement device (25) formed for mechanical reinforcement of the shoe-sole combination (105), constructed with at least one reinforcement web (37) arranged on at least one surface of the barrier material (33) and at least partially crossing the at least one through hole (31), and at least one walking-sole part (117) arranged beneath the barrier unit (35).

A water-vapor permeable shoe-sole combination (15) with an upper side (5) having at least on through hole (31) extending through the thickness of the shoe-sole combination, a barrier unit (35) with an upper side forming at least part of the upper side (50) of the shoe-sole combination, made of a water-vapor permeable barrier material (33) that forms a barrier against penetration of foreign bodies, by means of which the at least one through hole (31) is closed in a water-vapor permeable manner, a reinforcement device (25) formed for mechanical reinforcement of the shoe-sole combination (105), constructed with at least one reinforcement web (37) arranged on at least one surface of the barrier material (33) and at least partially crossing the at least one through hole (31), and at least one walking-sole part (117) arranged beneath the barrier unit (35).

A walking-assisted air-jet insole includes an insole base. A plurality of pressed-air outlet units that can generate airflow based on stepping pressure are provided on the insole base; the pressed-air outlet unit includes a cavity for retaining air. An upper part of the insole base is provided with an upper air hole that communicates with the cavity, and a lower part of the insole base is provided with an air sac part that is elastically deformed and restored based on the stepping pressure. A volume of the cavity can be changed based on the elastic deformation and restoration of the air sac part. A lower end of the air sac part is provided with a convex column that moves up and down based on the stepping pressure. The cavity includes an upper cavity portion and a lower cavity portion from top to bottom.

An athletic performance shoe with an open toe and an open heal for improved ventilation and comfort. The body of the shoe should be of suitable flexible material, such as the “Flyknit” fabric used by Nike, Inc. The shoe should include standard laces for enclosing the user's foot in the shoe as the laces suitably secure the shoe about the foot. The interior of the shoe should include soft, malleable padding which forms to the user's foot such that users with wide feet, narrow feet, or other factors will be comfortable in the shoe and the shoe will form around their foot without slipping or uncomfortably compressing the foot. A preferred embodiment would have a thin, highly-flexible sole. The open toe and heel being the primary features of the shoe.
