Abstract

Shoes, in particular sports shoes, and methods for their manufacture can correspond to a shoe that has an upper with a textile region in at least one of a forefoot region and a midfoot region, as well as a heel cap of the upper. The heel cap substantially surrounds a rear side, a medial side, and a lateral side of a heel of a wearer's foot when worn. The heel cap forms a heel region of the upper, and the heel cap is manufactured substantially as one piece from a non-textile flexible plastic material.

First claim

That which is claimed is:

1. A shoe comprises:
a forefoot region, a midfoot region, and a heel region;
a longitudinal axis aligned to have a rearward direction and a forward direction, the rearward direction oriented extending away from the forefoot region and toward the heel region, the forward direction oriented extending away from the heel region and toward the forefoot region, wherein rearmost refers to rearmost in the rearward direction and foremost refers to foremost in the forward direction;
a sole having an upper perimeter edge and formed of a first material;
an upper separate from the sole and coupled with the sole along the upper perimeter edge of the sole, the upper comprising at least an upper side panel and a heel cap, wherein the upper side panel is arranged to be at least one of adjacent or located in the forward direction of an arch of a wearer's foot when the shoe is worn by the wearer, the upper side panel comprising a textile fabric region in at least one of the forefoot region and the midfoot region, wherein the textile fabric region of the upper side panel is formed of a second material different from the first material;
a vertical axis aligned to have an upward direction and a downward direction, the upward direction oriented extending away from the sole and toward the upper, the downward direction oriented extending away from the upper and toward the sole, wherein topmost refers to topmost in the upward direction and lowermost refers to lowermost in the downward direction; and
a means for connecting the heel cap of the upper to the upper side panel of the upper;
wherein the heel cap at least partially surrounds a rear side, a medial side, and a lateral side of a heel of the wearer's foot when worn;
wherein the heel cap forms the heel region of the upper;
wherein the heel cap has a lowermost edge that terminates at or above the upper perimeter edge of the sole; and
wherein the heel cap is entirely formed of a third material different from the first material and the second material, and wherein the third material is a single piece of thermoplastic foam, the heel cap having a first surface and a second surface, wherein the first surface forms a portion of an exterior-most surface of the shoe, wherein the second surface forms a portion of an interior-most surface of the shoe facing a foot opening of the shoe for receiving a foot of the wearer, wherein the heel cap further comprises an upper rim edge around the foot opening, wherein a portion of the upper rim edge that is rearmost along the longitudinal axis defines a portion of the exterior-most surface of the shoe.

2. The shoe according to claim 1 , wherein the thermoplastic foam of the third material of the heel cap is formed of ethylene- vinyl-acetate (“EVA”).

3. The shoe according to claim 1 , wherein the heel cap further comprises a medial side wing and a lateral side wing, wherein each wing extends up to a fastening region of the shoe.

4. The shoe according to claim 3 , wherein the medial side wing and the lateral side wing each comprise a reinforcing element that is configured to receive a shoe lace.

5. The shoe according to claim 4 , wherein the reinforcing element comprises a greater stiffness than the third material of the heel cap and comprises a socket for an eyelet.

6. The shoe according to claim 3 , wherein the medial side wing and the lateral side wing each at least partially enclose a top surface of the foot of the wearer when worn.

7. The shoe according to claim 1 , wherein the heel cap comprises a medial side and a lateral side, wherein a top edge of the medial side and a top edge of the lateral side are positioned below an ankle of the wearer when worn, wherein the top edge of the medial side of the heel cap comprises a different design than the top edge of the lateral side of the heel cap in order to adapt to a different shape of a medial side and a lateral side of the wearer's ankle.

8. The shoe according to claim 1 , wherein the lowermost edge of the heel cap abuts the upper perimeter edge of the sole.

9. The shoe according to claim 1 , wherein the upper further comprises a tongue region located at a different position than the textile fabric region of the upper.

10. The shoe according to claim 1 , wherein the means for connecting comprises stitching along a juncture of the upper side panel with the heel cap.

11. The shoe according to claim 1 , wherein the lowermost edge of the heel cap terminates at the upper perimeter edge of the sole.

12. A shoe comprises:
a forefoot region, a midfoot region, and a heel region;
a longitudinal axis aligned to have a rearward direction and a forward direction, the rearward direction oriented extending away from the forefoot region and toward the heel region, the forward direction oriented extending away from the heel region and toward the forefoot region, wherein rearmost refers to rearmost in the rearward direction and foremost refers to foremost in the forward direction;
a sole having an upper perimeter edge and formed of a first material;
an upper separate from the sole and coupled with the sole along the upper perimeter edge of the sole, the upper comprising at least an upper side panel and a one-piece ankle collar, wherein the upper side panel is arranged to be at least one of adjacent or located in the forward direction of an arch of a wearer when the shoe is worn by the wearer, the upper side panel comprising a textile fabric region in at least one of the forefoot region and the midfoot region, wherein the textile fabric region of the upper side panel is formed of a second material different from the first material;
a vertical axis aligned to have an upward direction and a downward direction, the upward direction oriented extending away from the sole and toward the upper, the downward direction oriented extending away from the upper and toward the sole, wherein topmost refers to topmost in the upward direction and lowermost refers to lowermost in the downward direction; and
a means for connecting the one-piece ankle collar of the upper to the upper side panel of the upper;
wherein the one-piece ankle collar of the upper is entirely formed of a third material different from the first material and the second material, and wherein the third material is a single piece of thermoplastic foam, the one-piece ankle collar having a first surface and a second surface, the first surface forming a portion of an exterior-most surface of the shoe, the second surface forming a portion of an interior-most surface of the shoe facing a foot opening of the shoe for receiving a foot of a wearer, wherein the one-piece ankle collar further comprises an upper rim edge around the foot opening, wherein a portion of the upper rim edge that is rearmost along the longitudinal axis defines a portion of the exterior-most surface of the shoe, wherein the one-piece ankle collar has a lowermost edge that terminates at or above the upper perimeter edge of the sole.

13. The shoe according to claim 12 , wherein the thermoplastic foam of the third material of the one-piece ankle collar is formed of ethylene-vinyl-acetate (“EVA”).

14. The shoe according to claim 12 , wherein the thermoplastic foam of the third material of the one-piece ankle collar is formed of polyurethane (“PU”).

15. The shoe according to claim 12 , wherein the one-piece ankle collar comprises a medial side and a lateral side, wherein a top edge of the medial side and a top edge of the lateral side are positioned below an ankle of the wearer when worn, wherein the top edge of the medial side of the one-piece ankle collar comprises a different design
