An apparatus and method of making it is provided whereby a liquid-filled shoe insole is produced. The insole comprises discreet internal liquid-filled ampules which are strategically placed between upper and lower laminae and sealed in place to provide separate support for various parts of the foot.
A shoe incorporating dynamic Orthotic means which adapt to the foot in a prescribed manner, controlling heel "strike" and weight bearing loads, establishing a cup-shape to "catch" the heel and foot to stabilize it, balancing and maintaining the sub-talar joint in a neutral attitude and the mid-tarsal joint locked, enabling the foot and ankle to maintain optimum integrity as an efficient support and propulsion system, and resisting the symptomatic tendency for the sub-talar joint and foot to overcompensate and overstress the anatomy.
An innersole for shoes formed of a plastic material having an interior fluid tight main chamber, a quantity of liquid to be placed within the main chamber with the innersole being permanently sealed to prevent leakage of the liquid exteriorly of the innersole, the innersole having a sealed peripheral edge to contain the liquid, the innersole including totally enclosed liquid containing second chambers, the second chambers having a sealed periphery within said main chamber.
A weighted shoe insert (1) comprising a weighted base member (3), formed either as an integral portion of a shoe (8) or as a discrete insert sandwiched between an upper adhesively backed cover (2) and a lower adhesively backed cover (4). The base member 3 contains a series of perforations (28) and edge contours (17) which facilitate the shaping of the base member to conform with the human foot. In a second preferred embodiment, the base member is composed of a series of discrete elements (92) in which chafing between adjacent segments has been substantially reduced by the contouring of the edges (202a).
A hollow insole provided with non-communicating compartments which are filled with liquid to form individual foot-supporting cushions. Included in the invention is a method of making the insole.
An insole comprising a bladder which is filled with a water and air, and having a metatarsal and heel area for cushioning the foot of the user. Flow restrictions are located between the metatarsal and heel area of the bladder so as to restrict the flow of water and air from the metatarsal area to the heel area and vice versa. The flow restrictions are C-shaped seals in the bladder and provide a massaging action for the foot of the user.
