A dispersed-air footpad (10) consisting of a planar lower surface (12), an upper surface (18), a multiplicity of protrusions (20) and a multiplicity of air-passage channels (36). The protrusions (20), which protrude upward from the upper surface (18), have a geometric shape, are made of a soft, resilient material and can consist of either solid protrusions (38) or air or fluid filled cells (40). Each protrusion (38, 40) is bordered on each side by an air-passage channel (36) which traps a quantity of air. When the protrusions (38, 40) are cyclically compressed and decompressed, by a person walking or running, the air trapped in the air-passage channels (36) moves outward and inward respectively. This cyclic action causes the air to circulate over and around the upper surface (18) to provide a footpad (20) that is comfortable to wear, maintains the feet at a cooler temperature and aids in promoting healthy feet.
