__ Research Paper __ How do different shoe styles affect the height and success of an Ollie on a skateboard? __ Introduction __ Skateboarding or skating is an extreme sport, very popular with the modern generation. The first skateboard was invented in 1930s and 1940s when children made soapbox carts with a plank of wood and rollerskate wheels. It was basically a plank of wood with rollerskates which have been taken apart and nailed on the bottom with nails. These early day skateboards were used by surfers when the waves in the ocean were flat or general bad surfing weather. In 1972 the first wheels and trucks became available, which lead to tricks. At this time skating was gradually becoming more popular with all new styles of skating. There was freestyle, downhill, long jump and slalom. This was the beginning of skating as we know it now.
