A new shoe is manufactured with a double layer sole having visually distinctive wear indicating means between the layers. The same double layer construction with integral wear indicating means may also be applied to the heel portion of the new shoe. The ground engaging (outer, i.e., "wera") layer of either the sole, the heel or both sections is peeled off when it is worn down sufficiently to expose the wear indicating means which may be a distinctively colored, double faced pressure-sensitive adhesive tape. A spare sole and/or heel sold with the new shoe is cut to the exact size and shape of the corresponding portion of the original shoe by the shoe manufacturer and is provided with a pressure-sensitive adhesive coating on one surface that is covered by a strippable, protective layer. When the worn down, original outer sole and/or heel is peeled off, it is replaced by the spare.
