A method for utilizing a laser to etch a stratified material is disclosed.
The method includes providing a stratified material having at least two
layers that are secured together, the layers including a first layer and
a second layer. An incision is then formed in the stratified material
with a laser, the incision extending through the first layer to expose
the second layer. The stratified material may then be incorporated into
an upper of the article of footwear, for example. By exposing portions of
the second layer, properties of the second layer may be exposed in the
area of the removed first layer.
