Abstract
An article of footwear has an upper that is directly attached with the sole in an article of footwear mold. The sole has a film extending up sidewalls of the sole to a film edge that is prior to the sidewall and the upper joining. Method of manufacture of the article of footwear includes steps of positioning a film over a mold cavity and then securing the film to the mold. The film is heated and then drawn into the mold cavity under a vacuum. The film forms a liner of the mold cavity. A foam composition is injected into the lined mold cavity. As the foam composition expands, the foam composition interacts with and mechanically engages with the upper that is positioned at the mold cavity to allow for the mechanical engagement that results in the direct attachment of the sole to the upper.
