Abstract
A footwear construction includes a sole assembly having a first midsole platform of a first durometer and a second midsole platform of a second durometer, less than the first, so that the second midsole platform is softer than the first, and an outsole having an outsole upstanding cup wall surrounding the second midsole platform so as to protect it from abrasion, and to control a lateral and expansive movement of the softer second midsole platform, when lugs of the outsole are pushed upward toward the second midsole platform due to lug engagement with an underfoot terrain feature. The platforms can be constructed from a different durometer EVA or foam. The first durometer can be about 50-60 Asker C, inclusive and the second durometer can be about 35-45 Asker C, inclusive.
