Abstract

Claims (37)

1 . A shoe comprising:

an upper, the upper forming an interior portion for receiving a foot, the interior portion including a toe cavity and a heel cavity;

a midsole, the midsole having (i) a toe end, (ii) a heel end, (iii) an inner side, and (iv) an outer side, wherein a perimeter of the midsole is affixed to the upper thereby forming a bottom to the interior portion;

an insole that is affixed to the bottom of the interior portion; and

an outsole patch, the outsole patch having (i) a toe portion disposed on the toe end of the midsole, and (ii) a heel portion disposed on the heel end of the midsole, wherein an exterior contour of the outsole patch comprises a slope having a radius of a single curvature (i) configured to provide a clearance between a first face of the midsole and the ground when worn and (ii) a distance that is uniform between a portion of the exterior contour of the toe end of the outsole patch and the first face of the midsole;

wherein there is a region between (i) the heel portion of the outsole patch and (ii) the toe portion of the outsole patch, the region extending from the inner side to the outer side and occupying the first face of the midsole at a position intermediate the toe end of the midsole and the heel end of the midsole, thereby permitting the shoe to fold about the region; and

wherein

the insole is not stitched to the upper or midsole.

2 . The shoe of claim 1 , wherein the insole is affixed by glue to the bottom of the interior portion.

3 . The shoe of claim 1 , wherein the midsole is stitched to the upper thereby forming the bottom to the interior portion that is bounded by a first seam.

4 . The shoe of claim 3 , wherein a back edge of the toe portion of the outsole patch is within ¼ of an inch of a portion of the first seam.

5 . The shoe of claim 3 , wherein a back edge of the toe portion of the outsole patch is within 3/16 of an inch of a portion of the first seam.

6 . The shoe of claim 3 , wherein a front edge of the toe portion of the outsole patch is within ¼ of an inch of a portion of the first seam.

7 . The shoe of claim 3 , wherein a back edge of the heel portion of the outsole patch is within 3/16 of an inch of a portion of the first seam.

8 . The shoe of claim 3 , wherein a back edge of the heel portion of the outsole patch is within ¼ of an inch of a portion of the first seam.

9 . The shoe of claim 1 , wherein the outsole patch is stitched onto the first face of the midsole.

10 . The shoe of claim 1 , wherein the region has a spring constant of between 0.45 kilogram-force/inch and 0.55 kilogram-force/inch.

11 . The shoe of claim 1 , wherein the midsole is made out of leather.

12 . The shoe of claim 1 , wherein:

the midsole comprises a second face opposed to the first face running from the toe end to the heel end of the midsole, and

the interior portion further comprises a cushion insert that is glued to a heel portion of the second face of the midsole.

13 . The shoe of claim 1 , wherein the shoe further comprises a first groove having a depth of at least 3/64 of an inch is formed proximate to a perimeter of the outsole patch, and wherein the outsole patch is stitched onto a heel portion of the first face of the midsole with a first thread that occupies the first groove.

14 . The shoe of claim 1 , wherein the upper is formed as a single piece having a first end and a second end, wherein the first end and the second end are united by a second seam at the heel cavity.

15 . The shoe of claim 1 , wherein:

the upper is formed as a single piece having (i) a first end, (ii) a second end, (iii) a first edge, and (iv) a second edge,

the first end and the second end are united by a second seam at the heel cavity,

the first edge is stitched to the perimeter of the midsole thereby forming the bottom to the interior portion, and

a first portion of the second edge is characterized by an elastic restriction, wherein the portion of the second edge does not extend to the heel cavity.

16 . The shoe of claim 15 , wherein a second portion of the second edge is characterized by an Achilles cushion that provides an upper boundary to the heel cavity.

17 . The shoe of claim 1 , wherein

the upper is formed as a single piece having a first end and a second end,

the first end and the second end are united by a second seam at the heel cavity, and

a half moon piece covers a lower portion of the second seam.

18 . The shoe of claim 1 , wherein the outsole patch has a durability coefficient of between 0.8 and 1.5.

19 . The shoe of claim 1 , wherein the outsole patch has a durability coefficient of between 1.0 and 1.3.

20 . The shoe of claim 1 , wherein the region has a spring constant of between 0.40 kilogram-force/inch and 0.70 kilogram-force/inch.

21 . The shoe of claim 1 , wherein the radius of single curvature comprises an angle of inclination that varies between the portion of the exterior of the toe end of the outsole patch and a lower end surface of the outsole.
