    摘要： A one-piece, washable and sterilizable plastic shoe comprising a lower part with a top on which the foot bears and a bottom enveloping an outsole and a heel, and an upper part having ventilating openings in a substantially vertical lateral area, these openings having upper and lower outer boundary edges that are lower, respectively, than the corresponding upper and lower inner boundary edges thereof. The method for producing such a plastic shoe includes the steps of introducing mouldable plastic into a mould comprising top and bottom halves with a shoe last therebetween and simultaneously forming the lateral ventilating openings by means of spaced pins extending between the bottom-half mould and the last. The apparatus for producing the shoe comprises a mould having top and bottom halves with a shoe last therebetween and a plurality of pins extending from the bottom-half mould into removeable engagement with the shoe last. The pins are shaped and oriented to provide the desired configuration to the ventilating openings.

    摘要： A comfortable, clog construction having a specially shaped rigid upper and a rigid lower connected together along a mating circumferential step is disclosed herein. The clog is held comfortably and snugly to the foot of the wearer by a unique arrangement including a foam lining which cooperates with the rigid upper and lower to define a ''''keyhole'''' opening into which the skewed foot of the user may be inserted and then rotated to lock the foot securely in the clog. The clog is of plastic and provides a new modular shoe construction having the appearance of so-called ''''Dutch'''' shoes into which may be added a legging to provide a new and improved boot construction.

    摘要： A sandal having a structure consisting of unfoamed surface layers, an internal closed-cell layer and intermediate open-cell layers. This improved sandal is produced by adding a foaming material comprising short lengths of fiber and a blowing agent to a thermoplastic resin, melting the resulting composition, forcing the melt into a fixed-cavity mold and cooling the melt to solidify.
