The invention relates to a deodorising insole, in which the acidic odoriferous substances of the perspiration (principally butyric, isobutyric and isovaleric acid) are neutralised by reaction with a sparingly soluble, non-corrosive metal hydroxide. Those preferably suitable are the hydroxides of zinc, of magnesium and of nickel. The hydroxide is mixed with cellulose powder with the addition of a binder. The cellulose principally has the function of carrying the transpiration liquid sorptively onto the hydroxide particles on which the actual reaction takes place. In addition to it or in its place, a thin textile layer impregnated with the metal hydroxide can also be used as the carrier. The odoriferous substances are converted into non-liquid, odourless salts. The mixture of hydroxide and cellulose is applied in two to three layers, separated by an approximately 0.2 mm thick, net-like textile layer (such as, for example, bandage gauze), and covered above by a thin, absorbent textile layer. The sole base used is a known material such as leather, plastic and the like in a thin layer.
