Granted: 2023-04-11
Abstract: An article of footwear has an upper that is direct attached with the sole. 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 poisoned at the mold cavity to allow for the mechanical engagement that results in the direct attach of the sole to the upper. The film is then trimmed from the sole sidewalls at the film edge.
