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.
Claims20
An article of footwear comprising:
- a sole structure including a longitudinal direction associated with a length of the sole structure and the sole structure including a lateral direction associated with a width of the sole structure;
- a first longitudinal flex groove and a second longitudinal flex groove extending in the longitudinal direction, wherein the second longitudinal flex groove is disposed adjacent to the first longitudinal flex groove with no other longitudinal flex groove disposed between the first longitudinal flex groove and the second longitudinal flex groove;
- a first lateral flex groove and a second lateral flex groove extending in the lateral direction, wherein the first lateral flex groove is disposed adjacent to the second lateral flex groove with no other lateral flex grooves disposed between the first lateral flex groove and the second lateral flex groove;
- the first longitudinal flex groove intersecting the first lateral flex groove at a first intersection and the second longitudinal flex groove intersecting the second lateral flex groove at a second intersection;
- a diagonal flex groove, the diagonal flex groove being oriented in a direction between the longitudinal direction and the lateral direction;
- and
- wherein a first portion of the diagonal flex groove extends from the first intersection to the second intersection.
