An article of footwear, comprising:
- a sole structure including a bottom surface;
- a first cleat group disposed in a forefoot region of the sole structure and including a plurality of first traction elements integrally molded with the sole structure and extending away from the bottom surface, the plurality of first traction elements being arranged a first distance from a first common center point in a circular pattern and having two first traction elements of the plurality of first traction elements disposed proximate to one of a medial edge of the sole structure and a lateral edge of the sole structure;
- a second cleat group disposed in the forefoot region of the sole structure and including a plurality of second traction elements each having a different shape than the first traction elements of the plurality of first traction elements and being disposed proximate to the other of the medial edge and the lateral edge, at least one second traction element of the plurality of second traction elements being disposed closer to a heel region of the sole structure than at least one first traction element of the plurality of first traction elements;
- wherein each first traction element of the plurality of first traction elements includes a concave inner face and a convex outer face disposed opposite the concave inner face, the concave inner face facing towards the circular pattern and substantially following a contour of the circular pattern;
- wherein each first traction element of the plurality of first traction elements includes a junction where each first traction element of the plurality of first traction elements joins with the bottom surface, the junction of each first traction element of the plurality of first traction elements being spaced apart from the junction of an adjacent first traction element of the plurality of first traction elements by an expanse of the bottom surface;
- and
- wherein the concave inner face and the convex outer face of each first traction element of the plurality of first traction elements extends from a first end of the first traction element to a second end of the first traction element, the concave inner face of each first traction element having a continuous and uninterrupted constant radius from the first end to the second end of the first traction element.
