These heavy duty cleats have been designed and tested to go above and beyond in performance. Our cleats dig into the ice about the same time as your heel contacts the ice, passing even a 21-degree angle ice slope test to prove not just their piercing power but their anti-slip power, as the mid-sole design will stay dug in standing sideways on inclines and even preventing the cleat from slipping off while moving backward! Rip’s Cleats are made by Canadians for North American winters.
