Yes I had to show this. A person told me that they used elastics to go over the shoes of new junior curlers in their club untill they bought curling shoes. That the elastics gave the person extra grip (traction) on the ice. So I I had to try it out and she was right. It does give a little extra traction compared to your gripper shoe. But I can never see it being used on TV. But it is better than just your running shoes.
