The invention discloses a pair of sports shoes comprising a shoes body, a pressure generating device, a humidity sensor, a controller and a switch valve. A shoes chamber is provided at the heel of the shoes body, and the pressure generating device is arranged in the groove chamber. The upper work end of the pressure generating device is in contact with the lower surface of the insole of the shoes body; the humidity sensor is setted at the upper surface of the insole of the shoes body; the humidity sensor, the controller and the switch valve are electrically connected in turn, and the pressure generating device supplies power to the humidity sensor, the controller, and the switch valve, respectively; the controller controls the pressure generating device to stop or start energizing the solenoid valve tongue of the switch valve to close or conduct the gas passage.

A position indicator assembly, including first and second positioning units, is attached to a pair of shoes in positions which are spaced when the shoes are aligned together. Each positioning unit includes a first proximity switch element, at least one indicator, a battery and a second proximity switch element. The battery is electrically connected to the indicator when the first proximity switch element of one of the first and second position units is arranged a predetermined, spaced distance from the second proximity switch element of the other of the first and second positioning units in order to provide a visual and/or audible indication to a wearer that the pair of shoes are on the correct feet.

An apparatus and associated method contemplating an indicia marked on a package to identify a particular construction of color-mismatched footwear contained in the package. The indicia includes a brand identifying the footwear as being color-mismatched, a style identifying a characteristic construction of the footwear, and a generation level identifying an arrangement of the colors for the color-mismatched footwear.

The present invention is directed to a new and improved footwear orientation training system including a first and second shoe having a toe portion, a heel portion, a bottom surface, a top portion, and an inner side. First and second attachment members extend from a first end distally to a second end, the first end of the attachment members affixed to the inner side of the shoes. A fastener comprises a first fastener segment and a second fastener segment, the first fastener segment joined to the second end of the first attachment member and the second fastener segment joined to the second end of the second attachment member. The first attachment member is manipulable to engage with the second attachment member at their respective said fastener segments, thereby connecting said left shoe and said right shoe.

A position indicator assembly, including first and second positioning units, is attached to a pair of shoes in positions which are spaced when the shoes are aligned together. Each positioning unit includes a first proximity switch element, at least one indicator, a battery and a second proximity switch element. The battery is electrically connected to the indicator when the first proximity switch element of one of the first and second position units is arranged a predetermined, spaced distance from the second proximity switch element of the other of the first and second positioning units in order to provide a visual and/or audible indication to a wearer that the pair of shoes are on the correct feet.

An article of footwear includes an upper and a sole structure with a sole member. The sole member can be manufactured using a cushioning sole system that provides customized cushioning characteristics to different regions of a sole member. A user's foot morphology and/or preferences may be used to design the sole member. The sole member can include a set of apertures that are formed along various surfaces of the sole member.

An asymmetric pair of shoes to optimize performance during a sporting activity, the asymmetric pair of shoes, including: a first shoe having a first upper and a first sole attached to the first upper, wherein the first upper comprises a first support feature configured to provide increased support to at least one portion of the first upper during performance of a first predetermined action of a first foot of a wearer, and the first sole comprises a first traction feature configured to provide increased traction to at least one portion of the first sole during performance of the first predetermined action of the first foot; and a second shoe having a second upper and a second sole attached to the second upper, wherein the first support feature and first traction feature are not present at corresponding mirror-image locations of the second shoe.

A pair of sole plates for a complementary pair of articles of footwear may generally include a first article with a first sole plate and a second article with a second sole plate, where the first sole plate is asymmetrical with respect to the second sole plate. The first sole plate includes a first groove that extends along a first lateral side of the first sole plate, and the second sole plate includes a second groove that extends along a second medial side of the second sole plate. The asymmetry of first sole plate with respect to second sole plate may improve performance, flexibility, and agility during running and in particular, during athletic events along a curved track.

A shoe indicator system and kit are provided to visually aid differentiation of left and right shoes. The shoe indicator system comprises a left and right shoe comprising respective left and right shoe indicators irremovably integrated on a portion of the respective shoe itself or otherwise on auxiliary left and right shoe inserts or insoles. The left and right shoe indicators respectively define left and right-side portions of a figure that appears as a unified word, phrase, image, or the like when viewed together. Each left and right shoe indicator may be integrated on any portion of its respective shoe or auxiliary insert or insole so that accurate positioning of the shoes may be visually confirmed by the unification of the figure defined by left and right-side portions by a user prior to wear.
