ARTICLE OF FOOTWEAR AND METHOD OF MANUFACTURING AN ARTICLE OF FOOTWEAR
Last updated:
Abstract:
An article of footwear includes an upper and a strobel stitched to the upper at a series of stitches disposed in stitch holes that extend through the strobel. The strobel and the upper define a foot-receiving cavity with an inner surface of the strobel disposed at the foot-receiving cavity. A midsole is secured to the upper and an outer surface of the strobel is disposed at the midsole. The stitch holes are obstructed such that the stitch holes are not exposed to both the midsole and the foot-receiving cavity. Accordingly, when a flowable polymeric material is injected in a mold cavity to form the midsole with the lower portion of the upper and the strobel in the mold cavity, the stitch holes will not provide a path for entry of the flowable polymeric material into the foot-receiving cavity. A method of manufacturing an article of footwear is disclosed.
