Material elements incorporating tensile strands

Abstract:

An article of footwear or other product may include a material element having a first layer, a second layer, a third layer, and at least one strand. The second layer is positioned between the first layer and the third layer, and the second layer is formed from a thermoplastic polymer material. The strand is located between the first layer and the second layer, and the strand lies substantially parallel to the second layer for a distance of at least five centimeters. In this configuration, the thermoplastic polymer material may join the first layer and the third layer to the second layer. The thermoplastic polymer material may also join the strand to the second layer.
