A method of manufacturing a molded product comprising the steps of: providing a mold conforming to the shape of the product the mold serving to define one or more molding surfaces which are to be reproduced in an article formed via the mold; mounting in the mold an article including or forming an image comprising at least one device, logo, letter, word or words or combinations of these in such a way that most, if not all of the article lies within the mold out of contact with the or each molding surface; and injecting into the mold a supply of polymerisible material so as to immerse the article; the material, at least following polymerisation being flexible and so providing at least in part, a substantially transparent product; and withdrawing the product from the mold. Typically the step of providing product is directed to an article of footwear such as a shoe or swimming fin (also known as a flipper). The invention provides for a single stage product or the step of providing the mold conforming to the shape of the product serves also to juxtapose a previously formed or molded product for attachment to a product formed in the injection step. The invention extends to a molded product which is of flexible plastics material molded by way of the method.

What is claimed is: 1. A method of manufacturing a molded product in the form of a swimming fin comprising the steps of: providing a mold conforming to the shape of the swimming fin, the mold serving to define one or more molding surfaces which are to be reproduced in a fin formed by means of the mold; mounting in the mold an article comprising a clear strip incorporating at least one of a device, a logo, a letter, a word or a combination thereof in such a way that the at least one device, logo, letter, word or combination thereof lies within the mold out of contact with the or each molding surface; injecting into the mold a supply of polymerizable material so as to immerse the article; and the polymerizable material, at least following polymerization, being flexible and transparent so providing, at least in part, a substantially transparent product; and withdrawing the product from the mold following polymerization. 2. The method according to claim 1, further comprising the steps of coating the one or more molding surfaces which are to be reproduced in a fin formed by means of the mold with a release agent; and mounting the article between a pair of jaws support by the mold. 3. A molded swimming fin molded from a flexible and transparent plastics material by a method comprising the steps of: providing a mold conforming to the shape of the swimming fin, the mold serving to define one or more molding surfaces which are to be reproduced in an fin formed by the mold; mounting in the mold an article comprising a clear strip incorporating at least one device, logo, letter, word or combination thereof in such a way that the at least one device, logo, letter, word or combination thereof lies within the mold out of contact with the or each molding surface; injecting into the mold a supply of polymerizable material so as to immerse the article; and the polymerizable material, at least following polymerization, being flexible and transparent so providing, at least in part, a substantially transparent product; and withdrawing the product from the mold following polymerization. 4. The molded swimming fin according to claim 3, wherein the one or more molding surfaces which are to be reproduced in a fin formed by means of the mold are coated with a release agent; and the article is mounted between a pair of jaws support by the mold. 5. A method of manufacturing a swimming fin, the method comprising the steps of: providing a pair of molds conforming to the shape of the swimming fin to be molded with the pair of molds each defining at least one molding surface for being reproduced in a swimming fin formed by the pair of molds, and at least one of the pair of molds having a pair of opposed alignment jaws; providing a clear acrylic strip article with at least one of a device, a logo, a letter, or combination thereof; mounting the clear acrylic strip article such that the at least the device, logo, letter, word or combination thereof lies substantially within a plane defined by the pair of molds with an intermediate portion of the clear acrylic strip article suspended between the pair of opposed alignment jaws out of contact with the at least one molding surface of each of the pair of molds and the clear acrylic strip article lying within the plane defined by the pair of molds; selecting a polymerizable material which, following polymerization, remains flexible and transparent so to provide, at least in part, a substantially transparent molded swimming fin; injecting a supply of the polymerizable material into the mold and allowing the polymerizable material to surround the clear acrylic strip article and polymerize; and withdrawing the swimming fin from the mold following polymerization with the integrally molded within the swimming fin. 6. The method according to claim 5, further comprising the steps of coating each of the at least one molding surface which is to be reproduced in a swimming fin formed by the mold with a release agent; and mounting the article between the pair of opposed alignment jaws of the mold.
