The shoe sole comprises a flexible chamber therein with an inlet and an outlet. The shoe sole also comprises an inlet valve assigned to the inlet, and an outlet valve assigned to the outlet. The flexible chamber is arranged in the front region of the shoe sole, where an air inlet space is provided. The air inlet space is connected by the inlet valve to the chamber which is open to the environment via openings in the insole. The chamber is connected by the outlet valve to the outlet on the outer face of the shoe sole outside the insole. The chamber is filled almost completely with an elastically deformable material which absorbs air during its elastic expansion and releases air that has been previously absorbed during its compression. In this way, an air circulation that feels comfortable to the foot can be achieved in the shoe having this sole.

A ventilated shoe is provided. The ventilation shoe includes a bottom pad (10) with a peripheral wall (11) that has a front part (12), a rear part (13), a right side part (14) and a left side part (15). A plurality of right and left side holes (142, 152) are formed in the right and left side parts (14, 15) of the peripheral wall (11). A ventilation pad (20) is disposed on the bottom pad (10) to be surrounded by the peripheral wall (11), in a wave-like layer with alternate crests (21) and troughs (22), forming a plurality of tunnel vaults (23) each of which extends from the right side part (14) to the left side part (15). A right belt (30) and a left belt (40) are disposed on the right and left side parts (14, 15) of the peripheral wall (11) to be slidable between two positions.

The present invention relates to a check valve plate for shoes, comprising: a porous valve plate, which is stacked on the upper surface of a shoe sole having receiving grooves therein and thereby closes the receiving grooves, and which has elasticity; and multiple valves, which are formed inside the porous valve plate and are selectively opened/closed according to air pressure, and which are formed so as not to deviate from the thickness (t) of the porous valve plate.

A Waterproof, breathable shoe according to the present invention comprises an upper assembly (8) with an upper portion (10) including a breathable outer material (11) and with a bottom portion (20), said upper assembly (8) comprising a waterproof, breathable functional layer arrangement (18; 13, 21) extending over said upper portion (10) and said bottom portion (20). The shoe further comprises a ventilating sole element having a structure or material allowing for air flow through it, said ventilating sole element being attached to said upper assembly (8), wherein at least one lateral passage (50) extends from said structure or material through a side wall (702) of said ventilating sole element, said lateral passage (50) allowing for communication of air between said structure or material of said ventilating sole element and an outside of said ventilating sole element.

A temperature-adjustment shoe sole, including a supporting member. The supporting member is provided with an air guide channel. A semiconductor temperature control unit, wherein the semiconductor temperature control unit is arranged in the supporting member. The semiconductor temperature control unit has a first temperature control end and a second temperature control end. The first temperature control end of the semiconductor temperature control unit is in contact with an air fluid in an accommodating space to generate a first air fluid. The second temperature control end of the semiconductor temperature control unit is in contact with the air fluid in the accommodating space to generate a second air fluid.

An article of footwear includes a motorized tensioning system, sensors, and a gesture control system. Based on information received from one or more sensors the gesture control system may detect a prompting gesture and enters an armed mode for receiving further instructions. In the armed mode the system may detect a variety of different control gestures that correspond to different tensioning commands.

A footwear having a sole customized to a wearer's anatomy by receiving a foot model; generating an elevated foot model with a heel at a predetermined heel height from a ground and determining a structure to support a foot arch and a ball area of the foot model; and fabricating a high heel sole with the optimized structure to support the foot.

The shoe 100 includes the outer sole 10 brought in contact with the road surface, the midsole 20 arranged on the outer sole 10, and the upper 9 covering the foot from the upper side. The midsole 20 includes at the middle foot portion the cut-out portion 21 and the like opened to the outside and closed at the middle portion in the width direction.

A footwear article having a vacuum release mechanism is disclosed. The vacuum release mechanism equalizes pressure to release a vacuum created beneath the footwear article, thereby eliminating an undesired retention of the footwear article in high-viscosity materials such as mud or concrete. The vacuum release mechanism includes at least one check valve disposed in at least one fluid passageway formed in a sole of a footwear article. The at least one fluid passageway fluidly connects an exterior environment with an interior of the footwear article.
