A method and apparatus for producing a seam- less upper having an integrally molded sole includes a molding station with a first mold block, second and third mold blocks movable successively to the first molding block and within the axis thereof. A last is provided in the cavity formed in the first molding block and can be moved outwardly of the block. It is only when the second and third molding blocks have been closed successively onto the first molding block that plastics material is injected into the space defined between the last and the wall surfaces of the two mold- ing blocks. The split line of the mold is between the second and third mold parts forming the sole and the first mold part forming the upper, to allow the seam line to be formed along the edge of the sole or of the foxing of the boot so that it will be non-apparent on the boot per se.
