Footwear sole

Footwear upper

A footwear construction includes a sole assembly having a convoluted lower surface with multiple rolling peaks and valleys, and first and second midsoles having different durometers to provide dynamic stability, cushion and/or traction. The second midsole can include apertures that extend into some peaks so those peaks are compressible and conform well to underfoot terrain. The sole assembly can include certain lateral or medial peaks that transition to a perimeter of the sole assembly, and that are of a truncated shape with a sidewall to provide firmness and/or rigidity to the sole assembly around the perimeter. Other peaks can be disposed inward from the lateral or medial peaks and can be of a lesser firmness so those central peaks can provide cushioning and/or macro traction capabilities. A related method of manufacture also is provided.
