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.
