Claim 9:
10. A method of manufacturing footwear comprising:
forming a strobel by:
placing a first polymeric sheet in a mold cavity;
placing a tensile component on the first polymeric sheet;
placing a second polymeric sheet over the tensile component; and
welding the first polymeric sheet and the second polymeric sheet to one another to define a peripheral flange having a groove, and to define a polymeric bladder defining an interior cavity and configured to retain a fluid in the interior cavity, the polymeric bladder including the peripheral flange extending around at least a portion of a perimeter of the interior cavity, and the tensile component disposed in the interior cavity and secured to opposing inner surfaces of the polymeric bladder;
wherein welding the first and second polymeric sheets to one another includes welding a first weld and a second weld that are spaced apart from one another and extending lengthwise along the peripheral flange, with the groove extending lengthwise along the peripheral flange between the first weld and the second weld; and

stitching the strobel to an upper along the groove in the peripheral flange of the strobel so that a series of stitches extends through the peripheral flange at the groove with the groove in a distal surface of the polymeric bladder.
