Abstract

This invention relates generally to footwear with a shoe sole, including at least one insertable midsole orthotic. The insertable midsole orthotic is removably 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 insertable midsole orthotic. The insertable midsole orthotic 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 insertable midsole orthotic permits replacement of midsole material which has degraded or has worn out in order to maintain optimal characteristics of the shoe sole and allows customization for the individual wearer to provide tailored cushioning or support characteristics for the purpose of orthopedic, podiatric, corrective, prescriptive, therapeutic and/or prosthetic purposes.

Claims

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

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

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

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

said rounded part of the insertable midsole orthotic having uniform thickness extends from at least a centerline of the insertable midsole orthotic to proximate at least one sidemost extent of the insertable midsole orthotic, as viewed in a frontal plane cross-section when the insertable midsole orthotic 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 insertable midsole orthotic between parallel rounded portions of the outer and inner surfaces of the insertable midsole orthotic has a uniform thickness, as viewed in a frontal plane cross-section when the insertable midsole orthotic is upright and in an unloaded condition, and

said rounded part of the insertable midsole orthotic having uniform thickness extends to proximate both sidemost extents of the of the insertable midsole orthotic, as viewed in a frontal plane cross-section when the insertable midsole orthotic 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 insertable midsole orthotic between parallel rounded portions of the insertable midsole orthotic outer and inner surfaces has a uniform thickness, as viewed in a frontal plane cross-section when the insertable midsole orthotic is upright and in an unloaded condition, and

the insertable midsole orthotic includes at least two rounded parts having a uniform thickness, and wherein one said rounded part of the insertable midsole orthotic which has a uniform thickness is located on a side of the insertable midsole orthotic and extends at least proximate to a sidemost extent of the side of the insertable midsole orthotic, as viewed in a first frontal plane cross-section when the insertable midsole orthotic is upright and in an unloaded condition, and a second said rounded part of the insertable midsole orthotic which has a different uniform thickness is located on a side of the insertable midsole orthotic and extends at least proximate to a sidemost extent of the side of the insertable midsole orthotic, as viewed in a second, different frontal plane cross-section when the insertable midsole orthotic 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 as claimed in claim 1, wherein the insertable midsole orthotic 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 insertable midsole orthotic when the insertable midsole orthotic is upright and in an unloaded condition; and

said shoe sole comprises two or more ducts providing fluid communication between said at least three computer controlled compartments.

7. A shoe as claimed in claim 1, wherein the insertable midsole orthotic 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 insertable midsole orthotic, as viewed in a frontal plane cross-section when the insertable midsole orthotic 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 insertable midsole orthotic between parallel rounded portions of the outer and inner surfaces of the insertable midsole orthotic has a uniform thickness, as viewed in a frontal plane cross-section when the insertable midsole orthotic is upright and in an unloaded condition, and
