In general, certain embodiments of the present disclosure provide an augmented heel cup protective insert device for shoes. The insert device includes a posterior segment corresponding to the curvature of a heel of a shoe. The device also includes a medial wing, a medial parabolic formation that extends in a direction from top to bottom of the device, an inferior segment, and an angulated segment to meet the beginning of the edge of the heel on the medial side of the shoe.

An article of footwear includes a sole structure and an upper secured to the sole structure. The upper includes a heel section, lateral side section, medial side section, instep and toe cage that define an interior cavity operable to receive a foot of a wearer. At least a portion of the upper includes a laminate, where the laminate includes an inner layer facing the cavity, an outer layer forming an exterior of the shoe, and an intermediate layer disposed between inner and outer layers, the intermediate layer comprising a reinforcing layer having a rigidity that is greater than the rigidity of the inner and outer layers. The reinforcing layer extends from the lateral side section to the medial side section.

The invention relates to a method for manufacturing a shoe part by injection molding a material into a mold where an insert is placed. The insert comprises at least two separable insert parts, an upper insert part and a lower insert part, providing an injection channel in the region of the separation area between the two parts. The insert is placed in the chamber and the injection material is injected through a sprue channel in the mold into the injection channel and into a cavity, whereby the shoe part is formed. The mold is opened after the injection material has cured and the insert is separated into the upper and lower insert parts, thereby exposing the cured material in the injection channel.

A method of manufacturing a shoe upper according to the present invention includes: three-dimensionally forming an upper member; pre-heating the upper member such that a portion-to-be-reinforced of the three-dimensionally formed upper member is heated to a temperature equal to or higher than a melting point of thermoplastic resin powder; adhering the thermoplastic resin powder to the upper member so as to at least cover the portion-to-be-reinforced of the pre-heated upper member; further heating the upper member to which the thermoplastic resin powder is adhered and melting the thermoplastic resin powder adhered to the upper member; and hardening the melted thermoplastic resin powder to firmly adhere the reinforcing portion to the upper member.
