1. A sole structure of an article of footwear, the sole structure comprising:
a first outer region at least partially disposed a first distance from a longitudinal axis and having a first hardness;
a second outer region at least partially disposed a second distance from the longitudinal axis and having a second hardness that is greater than the first hardness; and
a third outer region at least partially disposed between the first outer region and the second outer region a third distance from the longitudinal axis and having a third hardness that is greater than the first hardness and less than the second hardness,
wherein the second distance is greater than the first distance, and the third distance is greater than the first distance and less than the second distance,
wherein the first distance, the second distance, and the third distance extend away from the longitudinal axis of the sole structure to an outermost periphery of the first outer region, the second outer region, and the third outer region, respectively, wherein the outermost peripheries of the first outer region, the second outer region, and the third outer region are disposed on a medial side or a lateral side of the sole structure, and
wherein the sole structure includes:
an outsole including the second outer region and the third outer region and defining a first passage; and
a midsole including a first outer pad disposed within the first passage, the first outer pad including the first outer region, and
wherein the outsole includes:
an outsole base layer including the second outer region and at least one opening; and
