Abstract
A fabric-covered shoe welt, and methods of making such a welt and using it to make shoes. The welt is an extruded polymer, and has fabric attached to at least one surface. The fabric is then bonded to the sole of the shoe. The fabric is selected to adhere well to both welt and sole, usually by allowing liquid to wick into the fabric before solidification.
Claims7
A method of making shoes, comprising,
- providing a polymer welt having a layer of fabric bonded to a surface of the welt;
- attaching the welt to an upper of a shoe;
- providing a mold for a shoe sole;
- filling the mold with a liquid precursor of a sole composition;
- placing the attached welt and upper in contact with the mold;
- inducing thee liquid precursor to at least partially penetrate the fabric layer by subjecting the liquid precursor and the fabric layer to activating conditions, wherein said activating conditions include heat generated by the interaction of the liquid precursor and a catalyst added to the liquid precursor;
- and
- solidifying the liquid precursor to form a solid sole attached to the welt.
