Abstract: An insole includes a heel collar formed by a relatively hard bottom member and a softer top member, the heel collar underlying the heel and arch region and having a channel in its upper surface. A forefoot pad has a forward portion that underlies the forefoot and a rear portion that fits in the channel of the heel collar and is adhered therein. Relatively softer foam pads are disposed within recesses in the lower surface of the forefoot pad in the forefoot and heel strike areas. A footwear system can include the insole in combination with a knit sock having thick padded ball and heel portions and a thinner arch portion, and the insole has an upper surface contoured to abuttingly mate with the sock. The footwear system can also include a shoe in combination with the insole, where the shoe functions to enhance the benefits of the insole.

Abstract: A modular cushioned insole support system that comprises a plurality of forefoot pieces, each having a dorsally disposed tongue capable of being disposed within a corresponding channel formed in each of a plurality of heel pieces, and optionally a heel cup disposed underneath the heel piece such that the heel piece is supported by the heel cup. The universal tongue-and-channel construction of each forefoot and heel piece enables selection by the user of the desired combination from the respective pluralities of forefoot and heel pieces. The forefoot pieces optimally vary in their construction to have certain sizing and differing cushioning effects. Similarly, the heel pieces optimally vary in their construction to have different alignment, cushioning, and/or anti-pronation effects.
