Problem Statement: Soling of foot ...accumalation of dirt
                                                      ....tracablable to sweat formation.

                   while some reputed brands like Hush Puppies provide for a porus cushion
                   seated on a sole ...which is washable.


Opportunity: Innovative footwear (all kinds) ...that lets or allows aircirculation

             ....a HeelNsole ...to be derived from a innovative polymer ...that breath's
                 viz. ideally some thing kind or porus ....succus air and releases air
                 .... should be possible given the context of application of pressure by foot.

                 One may understand how a sponge (absorbption of water ...application of pressure) ,
                 ....deriving a innovative polymer ...that can trap air ...release air ...absorb air.
 

                 lly ...a [shoe] upper's ...that allow air circulation ...
