Abstract
A traction element arrangement for a sole structure of an article of footwear is described. Traction elements of a first group are associated with a lateral side of the sole structure. Traction elements of a second group are associated with a medial side of the sole structure. Traction elements of the second group include multiple medial rotational traction elements that each have a plurality of individual traction elements arranged in a circular grouping. Each circular grouping is a different size to provide more or less rotational movement to the associated portion of the sole structure. In one embodiment, the shape of the traction elements corresponds to the shape of the circular grouping.
