Abstract
A strobel for an article of footwear includes a polymeric bladder defining an interior cavity and configured to retain a fluid in the interior cavity. The polymeric bladder has a peripheral flange extending around at least a portion of a perimeter of the interior cavity. A first bond secures opposing inner surfaces of the polymeric bladder to one another and extends transversely inward from a medial side of the peripheral flange only partway transversely across the interior cavity. A second bond is rearward of the first bond. The second bond extends transversely inward from a lateral side of the peripheral flange only partway transversely across the interior cavity. A tensile component is disposed in the interior cavity. An outer edge of the tensile component extends transversely inward at and borders a perimeter of the first bond and a perimeter of the second bond.
