Abstract

This invention relates generally to footwear such as a shoe, including an athletic shoe, with a shoe sole, including at least one removable midsole section formed by a midsole portion, wherein the removable midsole section is non-orthotic. The removable midsole section is inserted within the shoe upper, the sides of which hold it in position. The shoe sole includes a concavely rounded side or underneath portion, which may be formed in part by the removable midsole section. The removable midsole section may extend the length of the shoe sole or may form only a part of the shoe sole and can incorporate cushioning or structural compartments or components. The removable midsole section provides the capability to permit replacement of midsole material which has degraded or has worn out in order to maintain optimal characteristics of the shoe sole. The shoe sole can, in another embodiment, include at least one compartment containing a fluid, a flow regulator, a pressure sensor to monitor the compartment pressure, and a control system such as a computer processor capable of automatically adjusting the pressure in the compartment(s) in response to the impact of the shoe sole with the ground surface.

Claims

1. A shoe including:

a shoe upper and a shoe sole including at least a bottom sole;

at least a portion of said shoe sole being formed by a removable midsole section having an inner surface and an outer surface;

at least a portion of the sides of said shoe upper being attached directly to the bottom sole such that the shoe upper envelopes, on the outside, at least the removable midsole section of said shoe sole, such that the removable midsole section of said shoe sole is located within a structure formed by a combination of said bottom sole and a portion of said shoe upper that is attached to said bottom sole, as viewed in a frontal plane cross-section when the shoe sole is upright and in an unloaded condition;

the inner surface of the removable midsole section including at least one convexly rounded portion, said convexity being determined relative to a portion of the removable midsole section directly adjacent to the inner surface of the removable midsole section, as viewed in a frontal plane cross-section when the removable midsole section is upright and in an unloaded condition;

the outer surface of the removable midsole section including at least one concavely rounded portion, said concavity being determined relative to a portion of the removable midsole section directly adjacent to the outer surface of the removable midsole section, as viewed in a frontal plane when the removable midsole section is upright and in an unloaded condition;

each said concavely rounded portion of the outer surface of the removable midsole section being located on the removable midsole section at a location corresponding to the location of at least one convexly rounded portion of the inner surface of the removable midsole section so as to define a rounded portion of the removable midsole section located between said convexly rounded portion of the inner surface of the removable midsole section and said concavely rounded portion of the outer surface of the removable midsole section, as viewed in a frontal plane cross-section when the removable midsole section is upright and in an unloaded condition;

the removable midsole section including at least two computer controlled compartments, each compartment containing a fluid, and wherein at least a part of each of said at least two computer controlled compartments is located in a single frontal plane cross-section of the removable midsole section when the removable midsole section is upright and in an unloaded condition; and

at least one duct and/or valve providing fluid communication between said at least two computer controlled compartments.

2. A shoe according to claim 1, wherein at least a rounded part of each said rounded portion of the removable midsole section between parallel rounded portions of the outer and inner surfaces of the removable midsole section has a uniform thickness, as viewed in a frontal plane cross-section when the removable midsole section is upright and in an unloaded condition, and

said rounded part of the removable midsole section having uniform thickness extends from at least a centerline of the removable midsole section to proximate at least one sidemost extent of the removable midsole section, as viewed in a frontal plane cross-section when the removable midsole section is upright and in an unloaded condition.

3. A shoe as claimed in claim 1, wherein at least a rounded part of each said rounded portion of the removable midsole section between parallel rounded portions of the outer and inner surfaces of the removable midsole section has a uniform thickness, as viewed in a frontal plane cross-section when the removable midsole section is upright and in an unloaded condition, and

said rounded part of the removable midsole section having uniform thickness extends to proximate both sidemost extents of the removable midsole section, as viewed in a frontal plane cross-section when the removable midsole section is upright and in an unloaded condition.

4. A shoe as claimed in claim 1, wherein at least a rounded part of each said rounded portion of the removable midsole section between parallel rounded portions of the outer and inner surfaces of the removable midsole section has a uniform thickness, as viewed in a frontal plane cross-section when the removable midsole section is upright and in an unloaded condition, and

the removable midsole section includes at least two rounded parts having a uniform thickness, and wherein one said rounded part of the removable midsole section which has a uniform thickness is located on a side of the removable midsole section and extends at least proximate to a sidemost extent of the side of the removable midsole section, as viewed in a first frontal plane cross-section when the removable midsole section is upright and in an unloaded condition, and a second said rounded part of the removable midsole section which has a different uniform thickness is located on a side of the removable midsole section and extends at least proximate to a sidemost extent of the side of the removable midsole section, as viewed in a second, different frontal plane cross-section when the removable midsole section is upright and in an unloaded condition.

5. A shoe as claimed in claim 1, wherein said at least two compartments contain a liquid, gas or gel.

6. A shoe sole as claimed in claim 1, wherein the removable midsole section comprises:

at least three computer controlled compartments, and wherein at least a part of each of said at least three computer controlled compartments is located in a single frontal plane cross-section of the removable midsole section when the removable midsole section is upright and in an unloaded condition; and

two or more ducts and/or valves providing fluid communication between said at least three computer controlled compartments.

7. A shoe as claimed in claim 1, wherein the removable midsole section includes at least one internal sipe formed by internal sipe surfaces that can move relative to each other and at least a portion of said moveable internal sipe surfaces being in contact with each other in an unloaded condition.

8. A shoe as claimed in claim 7, wherein the at least one internal sipe partially or completely encapsulates a portion of the removable midsole section, as viewed in a frontal plane cross-section when the removable midsole section is upright and in an unloaded condition.

9. A shoe as claimed in claim 1, wherein at least a rounded part of each said rounded portion of the removable midsole section between parallel rounded portions of the outer and inner surfaces of the removable midsole section has a uniform thickness, as viewed in a frontal plane cross-section when the removable midsole section is upright and in an unloaded condition, and
