Abstract: A shoe or other footwear has a non-removable multi-layer foot-support member (FSM) embedded within the sole. The uppermost layer is a breathable, stretchable textile configured for direct contact with the foot, offering softness and elasticity. Directly beneath it is a containment layer made of elastic fabric partially infused or impregnated with silicone, which stabilizes and restrains the granular contents below. The central layer includes one or two or three sealed chambers filled with a cured mixture of silicone and polymeric granules, forming a deformable medium that yields under pressure and mimics natural granular terrain or sand. Beneath this is a synthetic textile layer that restricts lateral expansion of the granular mixture, and preserves chamber geometry during use. The bottom component is a semi-rigid base that structurally supports and anchors all overlying layers.

Abstract: A shoe or other footwear has a non-removable multi-layer insole. A middle layer of the insole has apertures that define several discrete storage chambers within the insole. Each storage chamber stores a mixture of particulate or granular materials, such as sand, powdered titanium, powdered aluminum, powdered talcum, powdered zinc. The insole or footwear further includes integrated components such as: electromyogram (EMG) sensors, temperature sensors, pressure sensors, humidity sensors, sweat sensors. The insole or footwear further includes integrated stimulating units, such as: Transcutaneous Electrical Nerve Stimulation (TENS) units, electrodes, infrared radiation units. Data is sensed by the sensors integrated in the insole or footwear, in response to a human foot stepping on the discrete storage chambers that store the particulate or granular materials, and optionally in response to stimulation operations.

Abstract: A non-removable insole, that is an integral part of a shoe or other footwear article, includes at least: a top layer, a middle layer, and a bottom layer. The middle layer of the insole has apertures or cavities, that define several discrete storage chambers within the insole. Each storage chamber stores a mixture of two or more particulate materials. The mixture includes one or more materials selected from Group A, which includes natural sand, synthetic sand, artificial sand, kinetic sand, silica, quartz. The mixture further includes one or more materials selected from Group B, which includes: powdered aluminum, powdered titanium, powdered zinc, powdered magnesia, powdered silver, powdered anti-bacterial agent, powdered metal, powdered talcum, grained cork, grained coal, grained wood.
