Abstract
A foot support system includes two or more pairs of insoles where each pair of insoles has physical properties different from the next pair of insoles, such as camber (side-to-side tilt). The user wears one pair of insoles for a set period of time before replacing it with the next consecutive insole in a serial order. Each pair of insoles has medial arches that are the same in height, that height varying from one pair of insoles to the next. Each insole comprises a base, a medial arch support, and a cover. Additional embodiments may include a heel cup for more secure fit.

- 1. Field of the Invention
- Insoles and orthotics have been used for decades to reduce, treat and prevent pain associated with walking, running, and general locomotion. Research indicates that insoles are effective in preventing and treating injuries ranging from plantar fasciitis to stress fractures to knee and back pain as well as increasing support and comfort in every-day shoes.
- While benefits exist for the use of insoles, it has been suggested that insoles and orthotics may be detrimental to long term muscle health. Certain muscles do not have to work as hard in specific orthotic situations. Consequently, the related muscle or muscle group, is less activated and may, over time, deteriorate.
- Humans evolved traversing across the natural ground barefoot, thus providing endless variations in foot positioning, resulting in greater foot and leg strength and health. With the addition of flat, hard urban settings and shoes, we now experience vary little variation in foot positioning attributing to repetitive lower leg and foot motion and muscle activation. While barefoot running is recently popular and claims to strengthen muscles in the feet and lower legs, it is not practical, safe, socially acceptable or stylish to walk around barefoot in most environments. Hence, an insole is needed that simultaneously provides support while offering continuous variations that prevent further weakening of the foot and lower leg muscles.
- 2. Description of Related Art
- Prior art includes customizable insoles with removable, adjustable parts. U.S. Pat. No. 4,557,060 includes exchangeable pieces that differ in hardness levels. They are adjusted based on the quality and function required by various sports shoes so that one insole is adequate for multiple sports. The adjustable features of other prior art are designed to offer customization options by accommodating multiple foot types as well as addressing various ailments (U.S. Pat. No. 4,841,648 to Shaffer, U.S. Pat. No. 6,105,283 to Park, U.S. Pat. No. 7,707,751 to Avent, U.S. Pat. No. 6,301,807 to Gardiner, U.S. Pat. No. 4,731,940 to Zanatta). However, the adjustable aspects of these insoles are intended purely for customization versus creating a series of insoles intended for one user alone and to be rotated or varied as a function of time, e.g. changing to a different insole with a different camber once per week.
- Additional prior art include removable inserts that provide a range of medial arch support positions. However none of the inventions share the purpose of the present invention. U.S. Pat. No. 6,990,756 to Johnson is an orthotic having a plurality of removable inserts designed to gradually train users feet to become accustomed to orthotic support. However with this invention the user relies on one final orthotic support. U.S. Pat. No. 5,138,774 to Sarkozi treats an initial foot support problem while allowing for subsequent readjustment of support and alignment in the arch and heel areas for minor adjustments as needed or to accommodate ongoing requirements caused by short and long term disabilities.
- As shown in the prior art, adjustments are made to a final configuration by having removable pieces and parts. They are not intended to be part of a regular rotation. Rather than having one pair of insoles with adjustable parts tending toward a final configuration, the present invention is simple and includes two or more complete pairs of insoles with varying camber (left to right tilt). The present invention can be used alone or on top of “perfect fit insoles” to provide camber variation. Eliminating removable pieces by supplying complete pairs of insoles provides greater ease of use, and is less cumbersome, particularly for the older population and others who may have difficulty with activities involving the fine motor skills and hand strength required to manipulate removable parts.
- The present invention is designed to provide additional foot support without the potentially harmful effects of relying on a single orthotic device and permanent positioning within a shoe. The present invention provides a user with two or more pairs of insoles where each pair of insoles has physical properties different from the next pair of insoles, such as camber (side-to-side tilt). The present invention is designed so that the user wears one pair of insoles for a set period of time before rotating to the next insole. The user cycles through the entire series of two or more insoles in serial, consecutive fashion.
- The present invention is a plurality of shoe insoles where each pair of insoles has a medial arch that varies in height from one pair of insoles to the next with each insole comprising: a base, a medial arch support, and a cover. Additional embodiments may include a heel cup for more secure fit.
- In some embodiments the insole covers the entire interior of the shoe from behind the heel of the foot to beyond the toes. In other embodiments the insoles only cover three quarters of the interior of the shoe, from behind the heel of the foot, to just before the toes. In another embodiment the insoles only cover just beyond the medial arch of the foot. In another aspect of the invention, the shoe includes one moisture absorbent additive dispersed over the interior of the insole.

Medial arch 28 is greater in height than medial arch 26 which is greater in height thanmedial arch 24. In the present embodiment themedial arches - While the present invention has been described in relation to preferred embodiments, the detailed description is not limited. For example, the intended use of the invention provides the user with more than one pair of insoles to rotate between on a regular basis. They may be distributed in packs of two pairs or more, with each pair having a notably different medial arch height and/or firmness. The preferred embodiment are three pairs of full-length insoles however, insoles may be three-quarter length, extending from behind the heel to just before the ball of the foot, or may be limited to the surface just under the medial arch of the foot.
