Methods and systems are provided for forming an article of footwear. In one example, forming the article of footwear includes using a perforated last during molding of a midsole of the article of footwear. The midsole may be attached to a seam of the upper of the article footwear to secure the midsole to the upper.

A method of manufacturing an article of footwear includes positioning an upper on a last that defines openings connected by one or more channels in the last, injecting a material through the one or more channels in the last, and forming a structure on the upper with the material.

A footwear moulding system for direct injection production of footwear includes a supporting mould, a last, an in-mould, and an injection channel. The supporting mould includes at least an in-mould support. The in-mould is elastomeric and the in-mould includes an in-mould outer surface configured to be supported by said in-mould support. The in-mould support includes at least one support side mould and a support bottom mould.

A molding device and a molding method are disclosed. The molding device includes an upper mold, a lower mold and a middle mold. The lower mold is disposed below the upper mold. The middle mold is disposed between the upper mold and the lower mold. The middle mold is moveably attached to the lower mold through a position control mechanism.

The present invention relates to a method for the production of plastic footwear (10; 100) of the full plastic type by means of moulding using a polyurethane mixture (M; P). The method comprises the steps of: providing a mould (20) having a mould cavity (22) defined by at least two impressions (28, 30) and designed to receive a shoe last (24) so as to define, when the mould (20) is closed, an interspace (26) having the shape and dimensions of the plastic footwear (10; 100) to be produced; spraying a polyurethane mixture (M, P) onto said at least two impressions (28, 30) of the mould cavity (22); inserting the shoe last (24) inside said mould cavity (22); closing the mould cavity (22) so that the sprayed polyurethane mixture (M, P) occupies said interspace (26); opening the mould (20), once at least the demoulding time (td) for the sprayed polyurethane mixture (M, P) has lapsed, such that the sprayed polyurethane mixture (M, P) has solidified inside the interspace (26) forming said plastic footwear (10, 100); extracting the shoe last (24) from the mould cavity (22); removing the plastic footwear (10, 100) from the shoe last (24).

A mold device for production of footwear by direct injection molding includes a first side mold, a second side mold, and a bottom mold. The first side mold and the second side mold are configured to be movable laterally in relation to each other and the bottom mold is configured to be movable vertically in relation to the first side mold and the second side mold. The first side mold, the second side mold, and the bottom mold are configured to define at least part of a mold cavity The mold device further includes a last holding device.
