The present invention relates to a composition of a hot-melt adhesive film and a method for producing a shoe sole. The composition of the hot-melt adhesive film comprises a hot-melt adhesive material and an electromagnetic radiation absorbing material. The hot-melt adhesive material includes ethylene vinyl acetate and thermoplastic materials. The electromagnetic radiation absorbing material is uniformly dispersed in the hot-melt adhesive material. Energy of an electromagnetic radiation can be absorbed by the electromagnetic radiation absorbing material, thereby producing thermal energy, further increasing temperature and adhering property of the hot-melt adhesive film. Therefore, a midsole and an outsole of the shoe sole can be adhered by the hot-melt adhesive film. Further, the hot-melt adhesive film is made from recyclable materials. Therefore, the hot-melt adhesive film is fully recyclable.

The utilization of heat in the manufacturing of footwear may be accomplished through microwave energy. The microwave energy is conveyed to the footwear components through a microwave transparent window of a tool. The microwave transparent tool window forms as least a portion of a part-contacting surface of the tool. Another surface of the tool is formed from a microwave reflecting material, such as aluminum. The footwear component(s) are exposed to microwave energy while within the tool such that the microwave energy passes through the tool window to cause a dielectric heating of one or more materials within a tool cavity of the tool.

A method of forming a plate for an article of footwear includes applying a first strand portion to a base layer including positioning adjacent segments of the first strand portion to form a first layer on the base layer. The adjacent segments of the first strand portion having a greater density across a width of the plate between a medial side and a lateral side at a midfoot region of the plate than at a forefoot region of the plate and at a heel region of the plate. The method also includes applying at least one of heat and pressure to the first strand portion and to the base layer to conform the first strand portion and the base layer to a predetermined shape.

A strobel for an article of footwear includes a base layer and an upper layer formed of a polymer material covering a portion of the top surface of the base layer, leaving a portion of the top surface of the base layer exposed about an entire periphery of the base layer. The upper layer is directly bonded to the base layer without any fastening members. A method of forming the strobel is also disclosed.
