Patent abstract
An article of footwear is disclosed. The article of footwear includes an outsole with a circular tread pattern. The circular tread pattern provides sufficient traction in all directions but also allows the wearer to pivot about a pivot portion. The circular tread pattern is generally large, and in some cases, the first and smallest circular tread extends less than 360 degrees. The pivot portion can include a slot that aids in flexibility. The outsole can also include a different tread pattern for the heel portion, or the circular tread pattern may also extend into the heel portion.
