Shoe

An article of footwear incorporating an upper formed by a forefoot component, a knitted workpiece, and a heel component is described. Each of the forefoot component, the knitted workpiece, and the heel component are separate from each other and joined along connection areas. Reinforcement elements cover the connection areas. In one embodiment, the knitted workpiece includes a collar portion and a throat portion extending from a forward end of the collar portion. The knitted workpiece also includes a medial lobe extending from one side of the throat portion and a lateral lobe extending from an opposite side of the throat portion from the medial lobe. The collar portion, the throat portion, the medial lobe, and the lateral lobe form a single unified knitted workpiece.

Upper for article of footwear incorporating a knitted butterfly workpiece

An upper for an article of footwear includes a three-dimensional engineered textile having an inner section, an outer section, and an intermediate section disposed between the inner section and the outer section. The intermediate section is attached to the inner section on one side and the outer section on an opposite side. The intermediate section extends through at least a forefoot region of the upper. In the forefoot region, the intermediate section includes a plurality of curving portions arranged adjacent to each other such that each curving portion of the plurality of curving portions is spaced apart from neighboring curving portions by one or more gaps. Air is configured to flow from an interior of the upper to an exterior of the upper through the one or more gaps between neighboring curving portions of the plurality of curving portions in the forefoot region of the upper.
