1. A footwear injection mold comprising:
a primary injection mold including:
a first side mold,
a second side mold, and
a bottom mold; and
a secondary injection mold configured to be fixed relative to the primary injection mold, the secondary injection mold defining at least part of an injection chamber for molding a footwear part, said injection chamber comprises a proximal surface defining at least part of a distal surface of the footwear part, and where the secondary injection mold comprises at least one protrusion, where the at least one protrusion comprises an upper contacting surface for contacting an upper part of a footwear, a proximal end connected to the secondary injection mold, a primary surface faced away from the injection chamber, and a secondary surface faced towards the injection chamber, and where a normal of the upper contacting surface is configured to intersect a center point of the upper contacting surface seen in a height direction, and where a protrusion plane is defined by the normal of the upper contacting surface along a width of the at least one protrusion, said protrusion plane configured to define a boundary between a primary half and a secondary half of the at least one protrusion, the primary half arranged between the protrusion plane and the primary surface and the secondary half arranged between the protrusion plane and the secondary surface, and where a height of the proximal end of the at least one protrusion is larger than a height of the upper contacting surface of the at least one protrusion, relative to the normal of the upper contacting surface,
wherein the primary half of the at least one protrusion includes a majority of a volume and/or a mass of the at least one protrusion.
