摘要:
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 greater than natural stability.

An athletic shoe sole for a shoe has side portions with concavely rounded inner and outer surfaces, as viewed in at least a heel area and a midtarsal area of the shoe sole. The rounded surfaces increasing at least one of lateral and medial stability of the sole. The concavely rounded portion of the sole outer surface located at the heel area extends substantially continuously through a sidemost part of the sole side. The rounded portion of the sole outer surface located at the midtarsal area extends up the sole side to at least a level corresponding to a lowest point of the sole inner surface. A midsole component of the shoe sole extends into the sidemost section of the sole side and also extends up the sole side to above a level corresponding to a lowest point of the sole inner surface. The concavely rounded portions of the sole midtarsal area are located at least at the sole lateral side. The sole outer surface of at least part of the midtarsal area is substantially convexly rounded, as viewed in a shoe sole sagittal plane.

A construction for a shoe, particularly an athletic shoe such as a running shoe, includes a sole that is constructed according to the applicant's prior invention of a theoretically ideal stability plane. Such a shoe sole according to that prior invention conforms to the natural shape of the foot, particularly the sides, and that has a constant thickness in frontal plane cross sections; the thickness of the shoe sole sides contour equals and therefore varies exactly as the thickness of the load-bearing sole portion. The new invention relates to the use of the theoretically ideal stability plane concept to provide natural stability in negative heel shoe soles that are less thick in the heel area than in the rest of the shoe sole. This new invention also relates to the use of the theoretically ideal stability plane concept to provide natural stability in flat shoe soles that have no heel lift, maintaining the same thickness throughout; such a design avoids excessive structural rigidity by using contoured stability sides abbreviated to only essential structural support elements to provide the shoe sole with natural flexibility paralleling that of the human foot. The abbreviation of essential structural support elements can also be applied to negative heel shoe soles, again to avoid excessive rigidity and to provide natural flexibility.

A construction for a shoe, particularly an athletic shoe such as a running shoe, includes a sole that conforms to the natural shape of the foot, particularly the sides, and that has a constant thickness in frontal plane cross sections. The thickness of the shoe sole side contour equals and therefore varies exactly as the thickness of the load-bearing sole portion varies due to heel lift, for example. Thus, the outer contour of the edge portion of the sole has at least a portion which lies along a theoretically ideal stability plane for providing natural stability and efficient motion of the shoe and foot particularly in an inverted and everted mode.

摘要:
A shoe sole particularly for athletic footwear for supporting the foot of an intended wearer having multiple rounded bulges existing as viewed in a frontal plane of the sole during a shoe unloaded, upright condition. The bulges include concavely rounded inner and outer portions for approximating the structure of and support provided by the natural foot. When utilizing multiple bulges, the shoe sole may include indentations between the bulges to define a flexibility axis of the shoe sole. The bulges can be located proximate to important structural support areas of an intended wearer's foot on either or both sides of the shoe sole or the middle portion of the shoe sole, or on various combinations of these locations. The bulges include side and upper midsole portions to improve stability while also improving cushioning and comfort. The bulges can be tapered as viewed in a horizontal plane to improve flexibility and reduce unnecessary weight.
摘要:
In its simplest conceptual form, the applicant's invention is the structure of a conventional shoe sole that has been modified by having its sides bent up so that their inner surface conforms to a shape nearly identical but slightly smaller than the shape of the outer surface of the sides of the foot sole of the wearer (instead of the shoe sole sides conforming to the ground by paralleling it, as is conventional). The shoe sole sides are sufficiently flexible to bend out easily when the shoes are put on the wearer's feet and therefore the shoe soles gently hold the sides of the wearer's foot sole when on, providing the equivalent of custom fit in a mass-produced shoe sole. This invention can be applied to shoe sole structures based on a theoretically ideal stability plane as a basic concept, especially including structures exceeding that plane. The theoretically ideal stability plane is defined as the plane of the surface of the bottom of the shoe sole, wherein the shoe sole conforms to the natural shape of the wearer's foot sole, particularly its sides, and has a constant thickness in frontal or transverse plane cross sections.
摘要:
A construction for a shoe, particularly an athletic shoe, which includes a sole that conforms to the natural shape of the foot shoe, including the bottom and the sides, when that foot sole deforms naturally by flattening under load while walking or running in order to provide a stable support base for the foot and ankle. Deformation sipes such as slits or channels are introduced in the shoe sole along its long axis, and other axes, to provide it with flexibility roughly equivalent to that of the foot. The result is a shoe sole that accurately parallels the frontal plane deformation of the foot sole, which creates a stable base that is wide and flat even when tilted sideways in extreme pronation or supination motion. In marked contrast, conventional shoe soles are rigid and become highly unstable when tilted sideways because they are supported only by a thin bottom edge.
