It's highly unlikely that there's someone who has never seen nor heard of snowboarding. But if you really have no idea what snowboarding is, just imagine it as surfing or skateboarding - only On Snow. Snowboarding is a relatively new winter sport wherein you ride an epoxy-fiberglass board (resembling a large skateboard) with your feet strapped on it, and manipulate gravity to go down a ski slope or a specially constructed pipe. The principle of snowboarding is to maintain your balance as you surf down a ski slope with both feet securely attached to the board via high-back or plate bindings..
Unlike skiers, who shift their weight from one ski to the other, snowboarders’ shift their weight from heels (heelside) to toes (toeside) as well as from one end of the board to the other. To stop the board's motion, they push their heels or toes down hard to dig the edge of the snowboard into the snow.
