A shoe comprising a sole and an upper on the sole. The sole comprises an insole, a midsole, and an outsole. The insole has a plurality of through holes extending from the insole top surface to the insole bottom surface. The midsole top surface comprises at least one longitudinal channel and a plurality of transverse channels. Each of the plurality of transverse channels intersect with the at least one longitudinal channel. The midsole further comprises pluralities of medial and lateral ports. Each port of the pluralities of medial and lateral ports are in fluid communication with one of the plurality of transverse channels. The plurality of through holes, the at least one longitudinal channel, the plurality of transverse channels, and the pluralities of medial and lateral ports are in fluid communication and adapted and configured to convey water from the insole out of the medial and lateral ports.

Provided is a shoe sole, wherein ventilation grooves recessed in the thickness direction of the shoe sole are formed in the upper surface part, the shoe sole has a forefoot portion that has an air intake port formed in at least one of a medial side wall and a lateral side wall in the side wall part to be in communication with the ventilation grooves and draw air from outside into the ventilation grooves, the shoe sole has a midfoot portion that has an air outlet port formed in at least one of the medial side wall and the lateral side wall to be in communication with the air intake port through the ventilation grooves and discharge air in the ventilation groove to the outside, and at least a part of the ventilation grooves constitutes an air intake groove extending obliquely rearward from the air intake port.

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 ventilation sole for footwear, the sole including: a communicating vent-hole through which the inside and outside of footwear communicate with each other to allow air to flow; and a valve selectively opening and closing the communicating vent-hole, wherein the valve includes: a housing module configured to have opposite ends being open such that a channel is provided therein to communicate with the communicating vent-hole; an open-close module configured with a first closing surface and a first through-hole; and a rotation module configured with a second closing surface and a second through-hole, and rotating to move a position of the second through-hole. Accordingly, a wearer can easily open and close the valve by rotating the rotation module according to the intention of the wearer, whereby air inside and outside the footwear can be circulated selectively and optimal foot conditions can be improved.

A sensor system is adapted for use with an article of footwear and includes an insert member including a first layer and a second layer, a port connected to the insert and configured for communication with an electronic module, a plurality of force and/or pressure sensors on the insert member, and a plurality of leads connecting the sensors to the port.

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 hidden drainage system for shoes, configured on the outsole of a shoe, in which the two sides of the outsole are provided with a plurality of curved sections that are curved inward; the top of the outsole is provided with a plurality of transverse drainage troughs and several longitudinal drainage troughs; each of the transverse drainage troughs extends along the direction of the width of the outsole, and both ends are communicated with each of the curved sections, so that the two ends of each of the transverse drainage troughs will not be exposed on the side face of the outsole; the longitudinal drainage troughs extend along the length of the outsole and are communicated with each of the transverse drainage troughs; thus, water entering the shoe will flow into each of the transverse and longitudinal drainage troughs, and be discharged from each of the transverse drainage troughs.

A breathable shoe, including an outsole arranged below a structural insert that is at least partially breathable, and below an upper. The outsole is at least partially breathable, including at least one sheet-like breathable element defined by a plurality of granules made of expanded material and having a uniform size, arranged in a substantially ordered manner and between which there are voids that form one or more channels through the breathable element that are permeable to air and/or vapor.

The present invention regards a sole for a sport shoe, work shoe or leisure shoe including a main body having a lower layer delimiting a surface, lower during use, set to come into contact with the ground and an upper layer set to come into contact with a foot of a user or to support from the bottom, during use, an insole.

Disclosed is a shoe having a foot-sole-contacting surface on which air passages extending along a plantar artery are formed to allow ventilation and prevent compression of the plantar artery. The shoe includes an upper having a space for accommodating a foot of a wearer, and a shoe sole including an insole accommodated in the space. The insole has a surface in contact with a foot sole of the wearer, and a plurality of air passages is engraved on the surface of the insole so as to extend along a plantar artery projected onto the foot sole.
