1. A method of manufacturing an article of footwear comprising:
obstructing stitch holes that extend through a strobel; wherein a series of stitches are disposed in the stitch holes and secure the strobel to an upper so that the strobel and the upper define a foot-receiving cavity; and
after obstructing the stitch holes, injecting a flowable polymeric material into a mold cavity configured as a midsole mold such that the flowable polymeric material contacts an outer surface of the strobel; wherein the obstructing the stitch holes inhibits the flowable polymeric material from passing through the strobel to the foot-receiving cavity via the stitch holes.
