Patent attributes
A sole structure for an article of footwear has a sole plate that may include a midfoot region, and also may include a forefoot region or a heel region. The sole plate may have a foot-facing surface with ridges extending longitudinally in the midfoot region and in the forefoot region or heel region. The sole plate may have a ground-facing surface with grooves extending longitudinally in correspondence with the ridges. A thickness of the sole plate from the foot-facing surface to the ground-facing surface may vary at a transverse cross-section of the sole plate through the ridges, or along a length of at least one of the ridges, or at both the transverse cross-section and along the length of the at least one of the ridges. The ridges may have crests at least some of which may extend non-parallel with one another in a longitudinal direction of the sole plate.
