Abstract
An article of footwear formed from a flat pattern. The article of footwear has a reduced seam construction to reduce manufacturing operations. A toe-end seam extending from a throat on a medial side of the article of footwear provides a seaming option. An acute-angle indentation on a lateral side of the throat allows the article of footwear to conform to a wearer's traditional foot. A heel-end seam having adjacent inner surfaces of medial and lateral portions of the upper may also be included to convert the flat pattern upper to a dimensional article of footwear that conforms to the wearer's traditional foot.

An article of footwear having a medial side, a lateral side, a toe end, a heel end, and a heel seam, the article of footwear comprising:
- a foot bed portion;
- a medial upper portion having a first inner surface and an opposite first outer surface;
- a heel tab;
- and
- a lateral upper portion having a second inner surface and an opposite second outer surface, wherein the medial upper portion and the lateral upper portion are secured to each other at a curvilinear seam extending from the foot bed portion on the lateral side across a toe box portion of the article of footwear to a throat opening on the medial side, wherein the medial upper portion and the lateral upper portion are discontinuous at the heel end lacking a continuous region and join at the heel seam extending from an ankle collar towards a bite line with the first inner surface of the medial upper portion and the second inner surface of the lateral upper portion adjacent at the heel seam, wherein the heel tab extends heelwardly.
An article of footwear having a medial side, a lateral side, a toe end, a heel end, and a heel seam, the article of footwear comprising:
- a foot bed portion;
- a medial upper portion;
- and
- a lateral upper portion comprising a throat-opening edge that extends from an ankle collar to a toe box portion, wherein the throat-opening edge comprises an acute angle indentation between an ankle opening and the toe box portion on the lateral side;
- and wherein an upper of the article of footwear includes an expanse extending continuously and seamlessly through the foot bed portion, the medial upper portion, and the lateral upper portion, wherein the medial upper portion and the lateral upper portion are secured to each other at a curvilinear seam extending from the foot bed portion on the lateral side across the lateral upper portion along the medial upper portion to a throat opening on the medial side.
