These Ray Davies traction pads by On A Mission are specially designed, tested and approved so you know they're made for the best, by the best The result is a thinner, lighter, grippier EVA. On A Mission's specially diamond grid design, which consists of tiny 1/8" thick squares which rest on top of diamond shaped foundation, provide the ultimate traction. The Eva Arch Bar acts as a support mechanism for your back foot as well. To top off this awesome traction pad design is the rolled tail kick, which like all OAM tail kicks slants at a 115 degree angle to provide optimum resistance for back foot pressure. The rolling grid surface over the kick leaves a clean, finished look which strikes the perfect balance between looks and functionality.
