Embodiment Construction

[0025]An article of footwear, such as a shoe, sandal, cleat, and the like, is comprised of one or more components. In the examples provided herein, a footwear upper and a bottom unit may form the footwear. A footwear upper, or referred to as an upper for short, is a foot-securing component of the footwear. The upper extends from the bottom unit and secures the bottom unit to a foot of a wearer. The upper may be formed from a variety of materials, such as leather, knit, woven, braided, felted, non-woven, and the like. Similarly, an upper may be made from a single material or a variety of materials. The upper may be a continuous material, a discontinuous material, a cut-and-sew combination, a cut-and-adhere combination, and the like. Therefore, it is contemplated herein that an upper may be formed from a variety of materials (e.g., organic, non-organic) and / or techniques.

[0026]A bottom unit is generally positioned between a wearer's foot and the ground. A bottom unit may be referred t...

Abstract

Joining a bottom unit, such as an athletic shoe sole, with an upper is achieved with an over molding process. A midsole core may be formed with a direct attach to an underfoot portion of the upper. The forming of the midsole core may be achieved with open cast molding or injection molding, for example. A shell may encapsulate the midsole core and also mechanically engage with the upper to further join the bottom unit with the upper. The shell and the midsole core may be formed from an elastomeric polymer such as polyurethane, thermoplastic polyurethane, ethyl-vinyl acetate, and/or silicone-based materials.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 62 / 430,220, entitled “Overmold Direct Attach Sole,” and filed Dec. 5, 2016. The entirety of the aforementioned application is incorporated by reference herein.TECHNICAL FIELD[0002]Aspects provide methods and systems for direct attaching a bottom unit, such as a shoe sole, to an article of footwear.BACKGROUND[0003]An article of footwear, such as an athletic shoe, is traditionally formed from an upper and a bottom unit. The upper and the bottom unit are joined together with the use of a bonding adhesive traditionally. However, the use of an adhesive adds additional steps to the manufacturing process, the adhesive can introduce failures into the footwear if the bond is not sufficient, and one or more primers may be used to ensure a bond between materials. Therefore, the use of an adhesive to join an upper and bottom unit can increase manufacturing costs and potential qua...
