    • A footwear injection mold includes a secondary injection mold defining at least part of an injection chamber. The injection chamber includes a proximal surface defining a part of a distal surface of a footwear part. The secondary injection mold includes a protrusion having an upper contacting surface, a proximal end, a primary surface faced away from the injection chamber, and a secondary surface facing the injection chamber. A normal of the upper contacting surface intersects a center point of the upper contacting surface. A protrusion plane is defined by the normal of the upper contacting surface along a width of the protrusion, and defines a boundary between a primary half and a secondary half of the 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. A height of the proximal end of the protrusion is larger than the height of the upper contacting surface of the protrusion, relative to the normal of the upper contacting surface.
