Abstract
Cleanliness insole for shoes comprising a first layer (10) positioned facing the foot and formed to promote the passage of perspiration from its upper to its lower surface, and a second rigid layer (20) whose upper surface is in contact with the lower surface of the first layer, the second layer delimiting cavities (23) which open onto the upper surface of the second layer. These cavities form a moisture-storage volume and are filled with an absorbent material (30). The moisture is thus stored by the absorbent material, thereby avoiding its transfer to the rest of the shoe and preventing the moisture from rising under the effect of foot pressure.
