Shoe and Footwear with Integrated Insole or Sole having Sand-Containing Chambers and having Sensors and Electrical Stimulation Units

A wearable article comprising:

• a footwear having an integral and non-removable insole,
• the insole comprising at least
• a bottom layer formed of Ethylene-Vinyl Acetate (EVA) polymer,
• a middle layer formed of Ethylene-Vinyl Acetate (EVA) polymer,
• and a top layer formed of one or more materials selected from the group consisting of:
• a co-polymer, a fabric, a textile, a polyether-polyurea copolymer, an elastic plastic layer, an elastomer, a stretchable plastic layer, an elastic rubber layer, a stretchable nylon layer, silicon, silicone, silicon glue, silicone glue;
• wherein the middle layer comprises apertures therein;
• wherein said apertures in the middle layer, with corresponding portions of the top layer that are above said apertures, and with corresponding portions of the bottom layer that are beneath said apertures, define two or more internal discrete storage chambers within said insole;
• wherein each of said internal discrete storage chambers stores therein a mixture of two or more particulate materials which comprise at least:
• (i) one or more materials selected from Group A, wherein Group A consists of:
• natural sand, synthetic sand, artificial sand, kinetic sand, silica, quartz;
• and
• (ii) one or more materials selected from Group B, wherein Group B consists of:
• powdered aluminum, powdered titanium, powdered zinc, powdered magnesia, powdered silver, powdered anti-bacterial agent, powdered metal, powdered talcum, grained cork, grained coal, grained wood, carbon nanotubes, carbon nanofibers, ground carbon, carbon powder, black carbon particles, charcoal particles, graphite, ground graphite, stainless steel powder, stainless steel particles, silicone glue, silicone caulk, Room Temperature Vulcanizing (RTV) silicone;
• wherein said footwear comprises:
• one or more electromyogram (EMG) sensors, that are integrated in said footwear, and that are configured to sense electrical activity from one or more muscles of a foot of a human wearer of said footwear, in response to stepping on said internal discrete storage chambers that store therein said mixture.
