A permanent spike dynamic outsole (10) having a plurality of traction sections (16a-16f) which have a plurality of dynamic traction elements (20) on their respective leading and trailing edges, under which are located debris channels (32a-32e) which act as a retraction areas for the dynamic elements (20) to go when walking on firm surfaces, thus reducing damage to greens and abrasion from pavement. The debris channels (32a-32e) additionally provide an exit path for any debris that may be caught under the dynamic traction elements (20).
