Abstract:
1. An outsole for a shoe, the outsole comprising: an outsole including a ground-engaging surface; a receptacle formed into the outsole; a first traction element adjacent a second traction element, the traction elements disposed at a radially spaced position from the receptacle, wherein: the first traction element is oriented in spaced relation from the second traction element to define a space between the first traction element and the second traction element, the traction elements project distally from the ground-engaging surface of the outsole, and the traction elements are static elements configured not to flex upon the application of the weight of the wearer of the shoe; a stud configured to couple to the receptacle in a predetermined orientation; a static spike extending from the stud that does not flex when the weight of the wearer of the shoe is applied thereto; and a dynamic spike extending from the stud, wherein the dynamic spike flexes radially outward from the stud when the weight of the wearer of the shoe is applied thereto, and wherein the dynamic spike extends at least as far as the radially spaced position of the traction elements, wherein the predetermined orientation of the stud aligns the dynamic spike with the space defined between the first traction element and the second traction element such that, during flexure, the traction elements guide the dynamic spike through the space defined by the first and second traction elements and the dynamic spike is positioned between the traction elements.
