Abstract
A dual-layered midsole for footwear includes an internal midsole layer and an external midsole layer, which are coupled to and separated by a Strobel board. The internal midsole layer may compress and expand with the movement of a wearer of an article of footwear including the dual-layered midsole, while the external midsole may provide stability and cushion for the wearer. Materials selected for the internal and external midsole layers may provide tuned viscoelastic properties to different areas of the midsole as a function of midsole layer thickness at each sole area.
