Abstract
An article of footwear includes an upper and a sole structure coupled with the upper. The sole structure includes a midsole that is coupled to the upper along an upper surface of the midsole and to an outsole along a lower surface that is opposite the upper surface. Both the upper surface and the lower surface are curved along a width of the sole structure to curve away from the upper and toward the outsole within a forefoot region, thus forming a rounded surface that extends throughout the forefoot region. A stiffening member is coupled to the midsole and extends from a heel end toward a toe end. The stiffening member includes a base disposed within at least a midfoot region and a plurality of tines that extend into the forefoot region from the base.

A sole structure for an article of footwear having an upper, the sole structure comprising
- a midsole that is coupled to the upper along an upper surface of the midsole and to an outsole along a lower surface that is opposite the upper surface, both the upper surface and the lower surface being curved along a width of the sole structure to curve away from the upper and toward the outsole within a forefoot region;
- and
- a stiffening member coupled to the midsole and extending from a heel end toward a toe end, the stiffening member including a base disposed within at least a midfoot region and a plurality of tines extending into the forefoot region from the base.
A sole structure for an article of footwear having an upper, the sole structure comprising:
- a midsole defining an upper surface configured to couple to the upper and a lower surface opposite the upper surface, the lower surface being curved in a forefoot region of the sole structure so that the lower surface has an ellipsoidal shape;
- and
- a stiffening member having a plurality of tines that extend from a base, the plurality of tines extending in a heel-to-toe direction within the forefoot region and including at least a first tine extending along a first curvature along a lateral side of the midsole to provide the lateral side of the midsole with a first stiffness and a second tine extending along a second curvature along a medial side of the midsole to provide the medial side of the midsole with a second stiffness.
A sole structure for an article of footwear having an upper, the sole structure comprising:
- a midsole that is configured to couple to the upper along an upper surface of the midsole and to an outsole along a lower surface that is opposite the upper surface, the lower surface being curved along both of a width and a length of the sole structure to form a continuously rounded and convex surface that extends throughout a forefoot region of the sole structure, and
- a stiffening member coupled to the midsole, the stiffening member having a plurality of tines that extend from a base, the plurality of tines extending in a heel-to-toe direction within the forefoot region and including at least a first tine extending along a first curvature along a lateral side of the midsole to provide the lateral side of the midsole with a first stiffness and a second tine extending along a second curvature along a medial side of the midsole to provide the medial side of the midsole with a second stiffness.
