Footwear, particularly athletic shoes, that has a sole structure copying
support, stability and cushioning structures of the human foot. Still
more particularly, this invention relates to the use of the shoe upper
portion to envelop one or more portions of the shoe midsole in
combination with portions of the shoe sole having at least one concavely
rounded portion of the sole outer surface, relative to a portion of the
shoe sole located adjacent to the concavely rounded outer surface
portion, and at least one convexly rounded portion of the inner surface
of the midsole component, relative to a portion of the midsole component
located adjacent to the convexly rounded portion of the inner surface of
the midsole component, all as viewed in a frontal plane cross-section
when the shoe sole is upright and in an unloaded condition.
