A healthcare footwear article includes an upper shoe body and a sole member provided underneath the upper shoe body and is connected with the upper shoe body to form an integral body. The upper shoe body and the sole member is configured from a material consisting of approximately 70% to approximately 80% of silicon rubber by weight, approximately 5% to approximately 20% of negative ion powder by weight, approximately 2% to approximately 7% of antiwear agent by weight, approximately 5% to approximately 20% of titanium powder by weight, approximately 0.1% to approximately 1.5% of vulcanizing agent by weight, approximately 5% to approximately 10% of infrared ray powder by weight, and approximately 0.1% to approximately 8% of dye by weight.

An insole includes a top surface, a bottom surface opposite to the upper surface, a plurality of protrusions protruding from the top surface, a plurality of recesses indenting inwardly from the bottom surface, and a plurality of vent holes . Each of the recesses has an inner end, and an outer end that is located at the bottom surface and that is larger than the inner end. Each of the vent holes extends from the top surface to communicate with the inner end of a corresponding one of the recesses.

A boot insole includes a sole base and multiple absorbing studs. The sole base is a flat pad that matches a foot contour and has multiple air vents. The absorbing studs are integrally and downwardly formed on a bottom surface of the sole base. The boot insole provides a shock absorbing effect without adding an air cushion to decrease the pressure on the foot, and also increases the ventilation between the foot sole and the orthopedic boot.

Shock/impact relieving footwear inserts that include a main body member having an upper surface and a lower surface, a plurality of spaced apart cavities extending downward from the upper surface, a plurality or protrusions extending downward from the lower surface, and a projecting wall extending from the upward surface. The main body member and/or the projecting wall can include one or more holes/vents for ventilation. The protrusions can be interconnected to form a lattice, or not interconnected. A primary aperture in the main body member can accommodate a resiliently compressible and slidable shock absorber.

A temperature modifying system for footwear having an air diverter positioned on top of the rear portion of the shoe insole, bores passing from an insole aperture beneath the air diverter to a supply port, and an AC system adapted to deliver conditioned air into the shoe through the supply port, bores, insole aperture and air channels located in the air diverter. The AC system is releasably connected to the shoe. A shoe may be retrofitted with the tubular members, supply port and insole aperture post-manufacture by drilling bores through the heel and insole.

A shoe insert assembly includes a panel that is selectively positioned in a shoe. The panel has an opening therein and the opening is aligned with a heel when the shoe is worn thereby facilitating pressure to be relieved from the heel. A cushion is positioned within the panel and the cushion absorbs pressure exerted by a foot onto the shoe thereby enhancing comfort of the shoe. A pad is coupled to the panel and the pad is aligned with an arch in the foot when the shoe is worn thereby enhancing comfort of the shoe.
