Abstract: Disclosed herein are embodiments of an acoustic amplification system for a shoe which includes an amplifier configured to couple to a sole portion of the shoe. The amplifier includes a body; an open-ended cavity disposed within the body; and a sound wave-amplifying conduit disposed within the body, the sound wave-amplifying conduit having opposing inlet and outlet ports, whereby the inlet port acoustically couples to the open-ended cavity and the outlet port acoustically couples to an ambient environment. Following, sound waves entering the inlet port from a sound wave-generating device received within the open-ended cavity are amplified within the sound wave-amplifying conduit to generate amplified sound waves which exit from the outlet port into the ambient environment, the amplified sound waves providing amplified sound.

Abstract: A closable drainage system for a sole of a shoe, the closable drainage system including a drain configured to communicate between sole top and bottom surfaces of the sole, the drain having opposing drain upper and lower faces; at least one drainage aperture element disposed within the drain, the drainage aperture element defining a drainage channel which communicates between the drain upper and lower faces; and a movable member overlaying the drain upper face, the movable member movable over the drain upper face to provide open and closed conditions of the drainage channel; whereby in the open condition, the movable member disposes to allow passage through the drainage channel and correspondingly, between the sole top and bottom surfaces; and whereby in the closed condition, the movable member disposes to preclude passage through the drainage channel and correspondingly, between the sole top and bottom surfaces.

Abstract: A hanger system including a body having opposing body first and second faces; a hanger element coupled to the body, the hanger element configured to facilitate hanging of the hanger system; a first support element coupled to the body, the first support element configured to support a first article; and an aperture element disposed within the body, the aperture element having an aperture element edge defining an aperture element opening which communicates between the body first and second faces; whereby the aperture element opening is configured to receive at least a portion of a bottle cap removably coupled to a bottle; and whereby the aperture element edge is configured to engage the bottle cap to facilitate removal of the bottle cap from the bottle.

Abstract: An article of footwear having an upper secured to an outsole in combination having three toe pockets, the first toe pocket having a configuration to separately receive within a big toe of a wearer, and the second toe pocket having a configuration to separately receive within a second toe of the wearer, and the third toe pocket having a configuration to receive within the remaining third toe, fourth toe and fifth toe of the wearer.
