Abstract

Claims (47)

1 . A shoe, comprising:

a sole;

an upper;

a heel cup comprising an upper portion, a midportion, and a lower portion,

wherein the heel cup extends from the sole to at least a portion of a rear ankle collar of the upper, and

wherein the heel cup is comprised of a polymer material;

wherein, in a first configuration, the upper portion of the heel cup has a downward incline with a first angle relative to a vertical line that is normal to a horizontal surface of a floor;

the upper portion capable of distorting into a second configuration under a load of a foot when donning the shoe, wherein in the second configuration the upper portion has a downward incline with a second angle relative to the vertical line, the second angle being greater than the first angle;

wherein the heel cup includes at least two reduced cross-sectional thickness portions located at approximately a mid-portion of the heel cup;

an interior foam layer adjacent to at least an interior wall of the upper portion of the heel cup,

wherein the interior foam layer is compressible,

wherein the interior foam layer is positioned to extend around portions of an ankle region of the foot, and

wherein the interior foam layer extends into a shoe opening, providing securement of the foot once inserted.

2 . The shoe of claim 1 , wherein a vertical cross-sectional shape of a rearmost portion of the heel cup comprises an S-wave.

3 . The shoe of claim 1 , wherein a profile of the heel cup has a pear-like shape.

4 . The shoe of claim 1 , wherein the upper includes at least one layer of elastic material positioned to stretch and create tension that enhances securement of a foot.

5 . The shoe of claim 1 , further comprising:

at least one fabric material covering the heel cup.

6 . The shoe of claim 5 , wherein the at least one fabric material extends above the heel cup.

7 . The shoe of claim 1 , wherein the polymer material is comprised of a thermoplastic.

8 . The shoe of claim 1 , wherein the polymer material is comprised of an elastomer.

9 . The shoe of claim 1 , wherein the heel cup is attached to an inner lining of the upper.

10 . The shoe of claim 1 , wherein the upper portion of the heel cup is configured to be lowered and extend backward away from the foot when donning the shoe.

11 . The shoe of claim 1 , further comprising:

at least one outer foam layer adjacent to an outer wall of the heel cup.

12 . The shoe of claim 11 , wherein the outer foam layer is thinner than the interior foam layer.

13 . The shoe of claim 1 , wherein the interior foam layer is bonded to the interior wall of the upper portion of the heel cup.

14 . The shoe of claim 1 , wherein the interior foam layer is also adjacent to a midportion interior wall of the heel cup and a lower portion interior wall of the heel cup, and

a portion of the interior foam layer that is adjacent to the interior wall of the upper portion is thicker than portions adjacent to the midportion interior wall and the lower portion interior wall.

15 . The shoe of claim 1 , wherein the interior foam layer is comprised of at least one of EVA and polyurethane foam.

16 . The shoe of claim 1 , wherein the interior foam layer is covered by an elastic textile.

17 . The shoe of claim 1 , wherein the elastic textile has wicking properties.

18 . The shoe of claim 17 , wherein the elastic textile is form fitted to the shape of the interior foam layer.

19 . A shoe, comprising:

a sole;

an upper;

a heel cup comprising an upper portion, a midportion, and a lower portion,

wherein the heel cup extends from the sole to at least a portion of a rear ankle collar of the upper, and

wherein the heel cup is comprised of a polymer material;

wherein, in a first configuration, the upper portion of the heel cup has a downward incline with a first angle relative to a vertical line that is normal to a horizontal surface of a floor;

the upper portion capable of distorting into a second configuration under a load of a foot when donning the shoe, wherein in the second configuration the upper portion has a downward incline with a second angle relative to the vertical line, the second angle being greater than the first angle;

the upper portion extends rearward of at least a region of the midportion;

a cross-sectional thickness of the heel cup including at least one reduced cross-sectional thickness portion located below the downward incline;

an interior foam layer adjacent to at least an interior wall of the upper portion of the heel cup,

wherein the interior foam layer is compressible,

wherein the interior foam layer is positioned to extend around portions of an ankle region of the foot, and

wherein the interior foam layer extends into a shoe opening, providing securement of the foot once inserted.
