Abstract (en)
[origin: ES8500730A1] An insole for shoes, with which, after having made a connection, preferably by sewing, between the insole and the shoe upper, a body of polyurethane forming the running sole and/or the foot bed is applied to the bottom side of the insole by foaming operation, consists of a fleece substantially formed of synthetic fibres and having arranged therein a reinforcing insert approximately extending in parallel relation to the upper side of the insole. At least the upper portion of the fleece, which is adjacent the upper side of the insole on which rests the foot, is impregnated with a dispersion or emulsion containing at least 1 percent by weight of hollow microspheres, the thin shell of which consists of a vinylidene chloride copolymer and the hollow core of which contains a gas. The hollow microspheres can already be present in the dispersion or emulsion prior to the impregnating step, it is, however, also possible to provide within the dispersion or emulsion compact particles from which are, after the impregnating step, formed the hollow microspheres in situ by supplying heat.
