When designs were being considered for the new Riedell Arius plate, it was clear that the standard cushions we were used to seeing on traditional king pins, were not going to work.
Riedell came up with the unique butterfly cushions which are ready to skate out of the package and no king pin adjustment is required. Originally there were to be two cushion hardnesses - extra soft and extra hard, now there are six different hardnesses to mix and match to find your ultimate set up!
