Champ Zarma cleat
The Champ Zarma cleat utilizes three layers in its design to combine traction and shock absorption, and better cushioning for your feet can relieve an aching back, too. The Zarma sandwiches a rigid base and a urethane, non-clogging traction element around a soft middle section. The multiple layers are designed to reduce the stress of impact.
