Abstract
The invention is a traction element for an article of footwear that reduces rotation in the footwear during activities such as golf. The traction elements are configured to penetrate the ground and include undercut surfaces that contact the ground. During a golf swing, for example, the ground will induce a force upon the undercut surfaces, thereby deforming the traction element and securely engaging the traction element with the ground. The traction elements may also have back surfaces opposite the undercut surface that assist with disengaging the traction elements following the golf swing.
