Footwear heel counter for easier foot entry or removal
The shoe includes a sole and an upper including at least one layer of elastic material positioned to stretch and create tension that enhances securement of a foot inserted into the shoe. The shoe includes a heel cup with polymer material, the heel cup affixed to the sole and upper, and the heel cup includes an upper portion, a midportion, and a lower portion. The shoe includes an interior foam layer adjacent to at least an interior wall of the upper portion of the heel cup, the interior foam layer being compressible, and the interior foam layer extends into the shoe opening, providing securement of the foot once inserted.
1. A shoe comprising:
a sole extending from a front portion to a rear portion of the shoe;
an upper comprising elastic material;
a heel cup comprising a uniformly molded flexible polymer material,
the heel cup comprising an aperture at a rear of the heel cup, wherein tension created by the elastic material of the upper at the aperture upon stretching facilitates securement of a user's foot within the shoe,
the heel cup comprising an upper portion attached to the upper, the upper portion being concave relative to the front portion of the shoe in a plane of the sole and flexing downward upon application of downward force by the user's foot when donning the shoe, temporarily widening a foot-receiving shoe opening into which the user's foot is inserted, and returning upward to surround a rear portion of a heel of the user's foot to facilitate the securement of the user's foot within the shoe after donning,
the heel cup comprising a lower portion attached to the sole; and
a foam layer positioned near a topmost region of the foot-receiving shoe opening and extending into the shoe opening, the foam layer configured to be compressed by the user's heel during foot insertion, and to facilitate the securement of the foot within the shoe after donning.
2. The shoe of claim 1 , wherein the upper portion of the heel cup comprises an angular strip connected to medial and lateral sides of the shoe, the angular strip having a rearward incline toward the rear portion of the shoe and providing increased rigidity in the area of the heel of the user's foot after the shoe is donned.
3. The shoe of claim 2 , wherein the angular strip has flexibility to curve from the medial and lateral sides to a rear of the heel portion of the shoe, to be depressed downward and rearward from the foot receiving shoe opening when the shoe is being donned, and to return to its initial elevated position after the shoe is donned.
4. The shoe of claim 1 , wherein the upper has an interior layer and an exterior layer, and the heel cup is an attachment at an outer surface of the exterior layer of the upper.
5. The shoe of claim 1 , wherein fabric material covers the heel cup on an interior of the shoe.
6. The shoe of claim 1 , further comprising:
a tongue having a front lower portion attached directly to the upper, and
elastic gore pieces attached to the upper and configured to maintain positioning of the tongue when the user dons the shoe.
7. The shoe of claim 6 wherein lateral edges of the tongue are directly attached to an interior portion of the upper.
8. The shoe of claim 1 , further comprising gore pieces configured to reduce a rearward pull of forward portions of the shoe during donning, facilitating a wider opening of the foot-receiving shoe opening when the user's foot is inserted.
9. The shoe of claim 1 , further comprising: a textile fitted to a surface of the foam layer that contacts the user's foot when the shoe is being donned.
10. The shoe of claim 9 , wherein the foam layer tapers along at least a portion of its vertical axis so that its volume is greater at an upper foam layer portion than at a lower foam layer portion.
11. The shoe of claim 9 , wherein the foam layer tapers along its longitudinal axis so that its volume is greater at a mid-portion than at end portions.
12. The shoe of claim 9 , wherein the textile comprises elastic textile having wicking properties.
13. The shoe of claim 9 , wherein glue is used to adhere the foam layer to the heel cup.
14. The shoe of claim 9 , wherein the foam layer is devoid of stitches or seams on its upper foam layer portion.
15. The shoe of claim 14 , wherein the upper foam layer portion of the foam layer is rearwardly inclined to facilitate guiding the user's foot into the shoe when donning the shoe, to return to its initial elevated position when the user's foot has fully entered the shoe.
16. The shoe of claim 9 , wherein the foam layer is bonded to the inner surface of the heel cup to provide cushioning.
17. The shoe of claim 1 , wherein the shoe is laced and comprises an eyestay layer providing structural support to the shoe.
18. The shoe of claim 1 , wherein the uniformly molded flexible polymer material comprises a thermoplastic.
19. The shoe of claim 1 , wherein the uniformly molded flexible polymer material comprises an elastomer.
20. The shoe of claim 1 , wherein the foam layer is comprised of at least one of EVA and polyurethane foam.
21. A shoe comprising:
a sole extending from a front portion to a rear portion of the shoe;
an upper comprising elastic material;
a compressible component formed of flexible thermoplastic material,
the compressible component attached at an outer surface of the upper and curving from medial to lateral sides of the sole, wherein tension created by the elastic material of the upper below the compressible component, upon stretching, facilitates securement of a user's foot within the shoe,
the compressible component flexing downward upon application of downward force by the user's foot when donning the shoe, temporarily widening a foot-receiving shoe opening into which the user's foot is inserted, and returning upward to surround a rear portion of a heel of the user's foot to facilitate the securement of the user's foot within the shoe after donning,
the compressible component attached to the sole at the medial and lateral sides of the sole;
a foam layer positioned near a topmost region of the foot-receiving shoe opening and extending into the shoe opening, the foam layer configured to be compressed by the user's heel during foot insertion, and to facilitate the securement of the foot within the shoe after donning the foam layer tapering along its longitudinal axis so that its volume is greater at a mid-portion than at end portions; and
an elastic textile having wicking properties that is fitted to a surface of the foam layer that contacts the user's foot when the shoe is being donned.
