Abstract: An odor and moisture absorbing insole or insock for covering the inner sole of footwear has a bottom open cell latex foam layer with a smooth bottom skin for engaging the bottom inner sole of footwear, an intermediate noncellular latex layer with discrete activated charcoal particles dispersed throughout and locked in this layer, a porous slippery abrasion resisting top fabric layer protecting the foot or sock of the wearer against discoloration or irritation, and spaced perforations extending through the three layers to enhance the circulation of air toward and away from the foot of the wearer into intimate contact with the charcoal in the intermediate layer as the open cell bottom foam layer is alternately compressed and expanded upon application and release of foot pressure on the insole as when walking. The open cell bottom layer and the top fabric layer are free from charcoal, and discoloration of the footwear, foot or sock is eliminated by bonding the charcoal particles in the intermediate layer.
