The necessary curling equipment consists of a set of stones, a brush for each curler. The best curlers use special shoes with one sole that grips the ice, and the other one is slippery, called a slider.
It allows curlers to slide with a stone during delivery, and the gripper is a removable sole to protect the slider. It also keeps the slider clean and allows the curler to be stable on ice. The stones weigh almost 20kgs each and consist of granite.
