the inner midsole surface of each of the midsole medial
and lateral sides comprising a convexly rounded portion, as
viewed in said heel portion frontal plane cross-section when the
shoe sole is upright and in an unloaded condition, the convexity
existing with respect to a section of the midsole directly
adjacent to each convexly rounded portion of the inner midsole
surface;
the outer midsole surface of each of the midsole medial
and lateral sides comprising a concavely rounded portion, as
viewed in said heel portion frontal plane cross-section when the
shoe sole is upright and in an unloaded condition, the concavity
existing with respect to an inner section of the midsole directly
adjacent to the concavely rounded portion of the outer midsole
surface;
the midsole comprising a first midsole portion located
completely on one side of a centerline of said midsole, said
first midsole portion having a first density or firmness, and a
second midsole portion located completely on another side of a
centerline of said midsole, said second midsole portion having a
second density or firmness which is different than the density or
firmness of said first midsole portion, as viewed in said heel
portion frontal lane cross-section when the shoe sole is upright
and in an unloaded condition;
each midsole side comprises a sidemost section of the
midsole defined by that portion of the midsole located outside of
a straight vertical line drawn through the sidemost extent of the
inner midsole surface of the midsole, as viewed in a frontal
plane cross-section when the shoe sole is upright and in an
unloaded condition;
at least a part of the midsole extends into the sidemost
section of each midsole side, as viewed in the heel portion
frontal plane cross-section when the shoe sole is upright and in
an unloaded condition;
the part of the midsole that extends into the sidemost
section of each midsole side further extends to above a lowermost
point of the inner midsole surface of the midsole on the same
sole side, as viewed in the heel portion frontal plane cross-
section when the shoe sole is upright and in an unloaded
condition; and
each sole side having a sole thickness that is greater than
a sole thickness in the sole middle portion, as viewed in said
heel portion frontal plane cross-section when the shoe sole is
