Patent US6675498 - Shoe sole structures - Google Patents
A shoe having a sole contour which follows a theoretically ideal stability plane as a basic concept, but which deviates outwardly therefrom to provide greater than natural stability. Thickness variations outwardly from the stability plane are disclosed, along with density variations to achieve a similar...http://www.google.com/patents/US6675498?utm_source=gb-gplus-sharePatent US6675498 - Shoe sole structures

US 6675498 B1
a midsole central part of the athletic shoe sole located between a midsole medial side portion and a midsole lateral side portion, as viewed in a shoe sole front plane cross-section in the heel area during an unloaded, upright shoe condition;
said midsole inner surface of said midsole central part comprising a convexly rounded portion at least through a midpoint of the midsole inner surface of said midsole central part, the convexity existing with respect to a section of the midsole directly adjacent to the convexly rounded portion of the midsole inner surface, all as viewed in the heel area frontal plane cross-section during an unloaded, upright shoe condition;
2. The shoe sole as set forth in claim 1, wherein said midsole central part comprises a section having at least two material layers, each layer composed of a midsole material of different firmness, as viewed in the heel area frontal plane cross-section during an unloaded, upright shoe condition.
the convexly rounded portion of the midsole central part of the midsole inner surface extends to one of said straight vertical lines, as viewed in the heel area frontal plane cross-section during an unloaded, upright shoe condition.
20. The shoe sole according to claim 19, comprising a concavely rounded portion of the midsole central part of the midsole outer surface extending to the other of said straight vertical lines, as viewed in the heel area frontal plane cross-section during an unloaded, upright shoe condition; and
The theoretically ideal stability plane for the special case is composed conceptually of two parts. Shown in FIG. 1, the first part is a line segment 31 b of equal length and parallel to line 30 b at a constant distance (s) equal to shoe sole thickness. This corresponds to a conventional shoe sole directly underneath the human foot, and also corresponds to the flattened portion of the bottom of the load-bearing foot sole 28 b. The second part is the naturally contoured stability side outer edge 31 a located at each side of the first part, line segment 31 b. Each point on the contoured side outer edge 31 a is located at a distance which is exactly shoe sole thickness (s) from the closest point on the contoured side inner edge 30 a.
