Abstract
Slipper-boots made of synthetic polymeric foam sheeting material comprise an upwardly flared foot-receiving throat having an upper opening with a first perimetral length to provide excess material for stress distribution and a lower opening having a second, smaller perimetral length to grip the wearer's ankle. Gussetted bottom soles also may be provided for additional width. An apparatus and method for making such slipper-boots comprise means or steps for simultaneously forming the heel of a leading slipper and the toe of a following slipper across an intermittently moving folded band of material, whereby slipper size may be varied by altering the time of movement of the folded band of material between formations of the slipper-boot heels and toes. Material folding means are also disclosed.
