[Quiet Man Cometh]

You ever watch curling? Players have a slider on one foot. That's so they can slide along the ice when they throw the stones (balancing on the sliding foot). The ice is textured, so if you have normal shoes on you don't actually slide much. Players will also use the slider food to travel along the ice, kicking off with the foot that has the grip on it. Takes some getting used to. The texturing is also why people sweep like crazy with the brooms, manipulating resistance and such to get the rock where they want it.
