This is a patent application for an X stitching method, specifically intended for the assembly of uppers by the system known as tied string—stringlaster, with particular application in the footwear segment. The invention includes application to an upper (1), for full assembly of shoes, using string traction (2) as the responsible element for closing the edges of this upper (1), against the mold (3); with the overlock type stitching hereby used as an example of realization.

An article of footwear includes a strobel that has 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 tensile component is disposed in the interior cavity and is secured to opposing inner surfaces of the polymeric bladder. The peripheral flange defines a groove extending along the peripheral flange. The strobel also includes a lasting component configured to extend along the peripheral flange around the at least a portion of the perimeter of the interior cavity. The lasting component is secured to the peripheral flange. A method of manufacturing footwear that includes the strobel is disclosed.
