Abstract: Systems and methods for joining polymeric materials together may use lasers or broadband infrared heat sources. The polymeric materials are arranged in an overlapping manner and then are exposed to the heat producing radiation for a sufficient time to join the polymeric materials together at the overlapped area. Such systems and methods may avoid the need to add an energy absorbing dopant to the materials being joined. Such systems and methods also may be used on transparent materials.

Abstract: An article of footwear includes an upper and a sole assembly that is operably coupled to the upper. The sole assembly defines a ground engaging surface. The sole assembly also includes a first portion and a second portion that are separated by an opening. The opening is open at the ground engaging surface and extends in a depth direction from the ground engaging surface. The article of footwear also includes a reinforcing tube that is fixedly coupled to at least one of the first portion and the second portion of the sole assembly. The article of footwear further includes a flexible cord including a first end, a second end, and a middle portion. The middle portion extends at least partially through the reinforcing tube and across the opening between the first portion and the second portion. The cord is configured to bias the first portion toward the second portion.

Abstract: An article of footwear includes an upper and a sole assembly. The sole assembly includes a groove that separates the sole assembly into first and second portions. Moreover, the article of footwear includes a flexible cord including a first end, a second end, and a middle portion. The middle portion extends through the sole assembly and across the groove between the first portion and the second portion.
