Abstract: A midsole for an article of footwear is strategically incised or scored to produce various straight and arcuate lines. Straight lines are integrated widthwise between edges on an arch side on an outer side. Arcuate lines are integrated into various places at the top of a toe portion, with at least one extending down through a midpoint in a heel portion. The latter arcuate line maintains curvatures that parallel curvatures on the outer side at some places and the arch side at other places. Also crossing at the midpoint in the heel portion are intersecting lines.

Abstract: An article of footwear with a marking system is disclosed. The marking system is configured to help locate one or more portions of a foot during training of an athlete. The marking system includes markings that extend from a lower surface of a sole system to an outer peripheral portion of a sole system.

Abstract: A sole structure for an article of footwear includes an outsole that has a body with a lateral side and a medial side, and has a plurality of tread elements extending from the body to establish a ground contact surface. At least some of the tread elements extend between the lateral side and the medial side and each include a front face, a rear face, and a bottom face that connects the front face and the rear face. The bottom face of each of the at least two of the tread elements has a width between the front face and the rear face that varies between the lateral side and the medial side forming different shapes of the tread elements. A method of manufacturing a sole structure for an article of footwear includes forming an outsole with such nonlinear tread elements.

At least some of the tread elements extend between the lateral side and the medial side and each include a front face, a rear face, and a bottom face that connects the front face and the rear face. At least some of the bottom faces each have a respective width between the front face and the rear face that varies between the lateral side and the medial side at least partially in correspondence with a predetermined wear pattern. A method of manufacturing a sole structure for an article of footwear includes forming an outsole with such nonlinear tread elements.

Abstract: An article of footwear with a multi-directional sole structure including a flex groove system is disclosed. The flex groove system includes a plurality of longitudinal flex grooves and lateral flex grooves that divide the sole structure into a plurality of segments. The flex groove system also includes a plurality of diagonal flex grooves that intersect the corners of the plurality of segments. The flex grooves system can provide enhanced flexibility for the sole structure and can enhance multi-directional flexing.

Abstract: An article of footwear with multiple cross sectional profile shapes disposed on an outer peripheral edge of a sole is disclosed. The multiple cross sectional profile shapes on the outer peripheral edge of the sole can help increase the lateral performance and lateral stability of a wearer of the article of footwear.

Abstract: An article of footwear is disclosed that includes at least one of an upper and a segmented sole structure. The sole structure may include an insole portion and a plurality of discrete sole elements disposed within an outsole unit. The insole is positioned adjacent the upper and may extend along a longitudinal length of the upper. The sole elements extend from the connecting portion, and the sole elements are separated by a plurality of flexible regions.
