    Abstract: A shoe includes a heel counter with a heel cup. The heel cup may be uniformly molded with an upper portion, midportion, and a lower portion. The upper portion has a smaller mediolateral length than the midportion, and a thickness of the heel cup decreases from a peripheral portion of the heel cup toward a central region of the midportion. The central region of the midportion provides flexibility of the heel cup, and the rearmost portion of the heel cup has an overall vertical S wave cross-sectional shape.

  • Publication number: 20240277114
    Abstract: A shoe includes a sole and an upper having a heel counter with a heel cup. The upper includes a foot receiving shoe opening. The heel cup is uniformly molded with an upper portion, midportion, and lower portion. On a vertical cross-section, the heel cup has a S wave shape and a thickness of the heel cup decreases gradually from a peripheral portion of the heel cup toward a central region of the heel cup. The heel cup is attached to an interior compressible layer, and the compressible layer extends into the shoe opening. The compressible layer may be compressed by a user's foot during insertion or removal of the user's foot, and may at least partially expand to hold an ankle of the user's foot once the foot is inserted.

  • Publication number: 20240260718
    Abstract: A shoe has an upper with a foot receiving shoe opening. A heel counter is located at a rear portion of the upper and includes a rigid heel cup. The heel cup has a lower portion, a midportion, and an upper portion having a curvature extending from a top edge of the heel cup and that is curved downward towards the shoe opening. On a vertical cross-section, the heel cup has a S wave shape. A compressible layer is located along an inner wall of the heel cup and is configured to curve around a portion of a user's ankle above the user's heel once donned. The compressible layer may be compressed during donning of the shoe and may at least partially expand to secure the foot within the shoe once donned.

  • Patent number: 12011064
    Abstract: An article of footwear includes a heel cup that is attached to the upper and extends from the sole structure to at least a portion of the rear heel collar of the upper. The heel cup may be uniformly molded with an upper portion, midportion, and lower portion and the upper portion has a smaller mediolateral length than the midportion, and the midportion and lower portion form a concave structure that receives the heel. The upper portion has a first configuration and is capable of distorting into a second configuration under a load of a user's foot when the user is donning the footwear. In the second configuration, at least part of the upper portion is lowered and is capable of returning to the first configuration after the load of the user's foot is removed. The midportion includes a peripheral portion that may be thicker than a central portion.
