Abstract: Footwear articles for walking are provided. In one example, a footwear article may include a midsole with a lower surface of constant curvature extending from a heel of the midsole to a toe of the midsole, wherein the lower surface maintains the constant curvature throughout a stance phase of a walking gait. In this way, a smooth step-to-step transition and a smaller range of oscillation of the center of mass of the wearer is achieved, and energy expenditure during walking is reduced. In turn, a wearer of the footwear article may smoothly walk for extended periods of time with reduced fatigue.

Abstract: A footwear article is provided comprising an upper and a wear guard. In at least one example, the wear guard may be structured with bellows extending along an edge of a lacing structure of the footwear article, the bellows positioned between the lacing structure and a toe of the footwear article.

Abstract: A footwear article is provided herein. The footwear article may include a sole coupled to a cord structure. The cord structure may include interconnected bights in a vamp cord and a rand cord forming a loop line extending along at least a portion of the footwear article.

Abstract: A footwear article is provided having an upper and a wear guard arranged across a vamp of the upper. In one embodiment, the wear guard is configured with a grid pattern of raised articulations extends entirely across a width of the vamp. In another embodiment, the footwear article also include a heel guard positioned above a heel region of the upper. In yet another embodiment, a tab may be coupled to the heel guard.

Abstract: Systems and methods for automatically producing a cord structure are provided herein. In one embodiment, a method comprises automatically forming, with at least one robotic arm, a first plurality of loops in a first plane, and automatically forming, with the at least one robotic arm, a second plurality of loops in a second plane orthogonal to the first plane, the second plurality of loops slippably engaged with the first plurality of loops. In this way, cord structures may be quickly constructed, thereby reducing labor input and expense.

Abstract: A footwear article is provided comprising an upper and a wear guard. In at least one example, the wear guard may include an overlay formed with bellows positioned along a lacing structure of the footwear article, wherein the wear guard is a different material than the upper of the footwear article.

Abstract: A footwear article is provided herein. The footwear article may include a cord structure including interconnected bights in a vamp cord and a rand cord forming a loop line extending along at least a portion of the footwear article, and further including an anchor cord extending along the portion of the footwear article and parallel to the loop line. The rand cord may couple to the anchor cord. In this way, the cord structure may be tensioned independently of other upper materials.
