Abstract: An odor absorbing insole or insock covering the inner sole of footwear has a bottom inner sole engaging open cellular resilient cushion layer, an intermediate nonwoven random fiber felt mat porous layer having the fibers coated with an odor and moisture absorbing chemical such as activated charcoal or silica gel, and a porous slippery abrasion resisting top fabric layer protecting the foot or sock of the wearer against discoloration or irritation. The layers of the insole are laminated into integral unitary relation by heat sealing or by binders which do not impede flow of air. The alternating application and release of foot pressure on the insole as when walking will alternately compress and expand the open cellular cushion layer to pump air through intermediate layer and abrasion resisting top layer for circulating air in the footwear around the foot into intimate contact with the chemical for efficient absorption of moisture from foot perspiration and destruction of foot odors.

Abstract: A multi-layer insole for disposition in an article of footwear to insulate the foot from the cold developed in the sole and sock lining, if any, of the footwear from walking on a cold surface, the insole being sufficiently thin to fit in the footwear satisfactorily to the user without requiring any extra size of shoe, boot or the like and being highly effective in maintaining the foot warm in cold weather.

Abstract: A pressurized package containing a conventional pressure propellant is divided into two compartments arranged for mixing of their contents simultaneously with dispensing, one compartment containing a peroxide solution and the other containing a hair treating composition including certain selected compounds in quantity sufficient to prevent development of unsafe pressure should the peroxide decompose within the package.
