The present invention provides a cushion partially or entirely composed of a foam, the foam composed of a polymer composition that includes a homopolymer or a copolymer including a constituent unit derived from farnesene.

The present invention is a type of shock absorbent shoes with the heel portion of each shoe bottom divided into an upper and lower portion; by having a horizontal gap between the outsole and midsole or along the midsole. Also, several resistive devices are each connected to said lower portion and said upper portion or the upper of said shoe. Whereby, having resistive device attached to the side of both the outsole and midsole and/or upper; allow them to be more lengthy, hence more energy can be store and released along, their entire length, to the point where both the outsole and midsole touches, therefore, the amount of play the resistive devices have is dependent on the amount of space between said outsole and midsole. Each shoe also includes a small detachable power bank charger device for use of partially charging of cell phone, blue tooth speakers, wireless ear buds etc. Each power bank is charged by electrical pulse from a piezoelectric device via a circuit board and is fitted to a modest structure on the shoe such that it does not cause the shoes to look bulky or feel uncomfortable.

The present disclosure relates to footwear. The footwear according to an embodiment of the present disclosure includes a first sole having a first base portion configured to come into contact with the ground surface, and a plurality of first protrusion portions protruding from the base portion in a direction opposite to the ground surface, and a second sole having a second base portion bonded to ends of the plurality of first protrusion portions, and a plurality of second protrusion portions protruding from the second base portion in the direction of the first base portion and having ends bonded to the first base portion.

A protective device, in particular a safety toe cap, for use with an article of footwear is provided. A safety toe cap of the present technology includes one or more strain hardened portions configured to strengthen or reinforce sections of the safety toe cap against impact, particularly from above. The one or more strain hardened portions have increased strength in relation to adjacent non-strain hardened portions and therefore may maintain adequate protection of a user's toes and foot, while simultaneously allowing for lowered material use and a device with a lightweight, streamlined profile.

Articles of footwear, systems, and methods include an upper portion, a lower portion, secured to the upper portion, the lower portion including an out-sole and an airbag assembly. The airbag assembly includes a first sheet and a second sheet forming a seal therebetween around a perimeter of the first and second sheets. The airbag assembly further includes an electronic assembly, comprising a circuit board and electrical conductors disposed on the circuit board, wherein an internal portion of the electronic assembly is disposed between the first and second sheets and within the seal formed therebetween and an external portion of the electronic assembly is disposed outside of the seal.

The present disclosure provides footwear with an internal metatarsal guard and a related manufacturing method. In the depicted embodiment, the metatarsal guard is internal in that it is located under the outer layer of the footwear. In the depicted embodiment, the existence of the metatarsal guard can be visually detected from the outside of the footwear being that the metatarsal guard is located in a raised area in vamp of the footwear. The footwear is constructed such that the metatarsal guard does not impinge into the foot volume of the footwear, and the metatarsal protection also is arranged and configured to maintain a high degree of flexibility in the footwear.
