Shoe and footwear with integrated insole or sole having sealed discrete elastic chambers storing a synthetic granular mixture that mimics stepping on natural sand

A footwear for a human foot, comprising:

• a foot-support member disposed within a sole, wherein the foot-support member is five-layer sandwich component that comprises:
• (a) an uppermost skin-contacting elastic textile layer (171), having a thickness in a range of 0.5 to 3.0 millimeters, characterized by having breathability and two-way stretching capability, configured to be in direct plantar contact with the human foot;
• which is attached on top of (b) a containment layer (172) formed of elastic fabric, that is partially impregnated with post-cured silicone and has a micro-porous inner shell that captures and stabilizes adjacent granular material;
• that is integrally and non-detachably attached on top of (c) an elastic granular-mixture layer (181, 182, 183), having a thickness in a range of 10 to 30 millimeters, partitioned into exactly one of:
• a single elongated sealed chamber, two discrete sealed chambers, or three discrete sealed chambers;
• wherein each chamber of the elastic granular-mixture layer (181, 182, 183) contains therein a cured mixture of:
• (i) Silicone, and (ii) polymeric granules;
• wherein said cured mixture of the elastic granular-mixture layer (181, 182, 183) deforms in response to stepping thereon, and simulates stepping on sand;
• which is attached on top of (d) a lower stabilization layer (174) formed of synthetic textile, which constrains lateral bulging of said cured mixture, and which maintains uniform chamber geometry of one or more discrete chambers of the elastic granular-mixture layer (181, 182, 183) to preserve biomechanical alignment throughout repeated stepping;
• which is attached on top of (e) a semi-rigid base layer, configured to support and hold in place all layers located above the semi-rigid base layer.
