An article of footwear includes an upper for holding a foot of a wearer
and a sole having an outsole plate. Several ground engaging members
extends downwardly from the outsole plate to provide traction. The
outsole plate includes a flex control member composed of a superelastic
shape memory material or a nickel-titanium alloy. The flex control member
can be coupled to an inside surface, or bottom surface of the outsole
plate. The outsole plate may include a rearfoot region, a midfoot region,
and a first metatarsal head region, in which the regions generally
correspond to the skeletal structure of a human foot. The flex control
member extends from a medial side of the rearfoot region through the
midfoot region and into the first metatarsal head region of the outsole
plate. The ground engaging members may be positioned to extend from the
location of the flex control member.
