HardFlip
A hardflip combines a frontside pop shuvit with a kickflip. This trick is awkward to execute, and the board sometimes appears to move vertically through the legs—the degree of verticality is determined by the front-foot action
50-50 Grind
In skateboarding, Grinds are tricks that involve the skateboarder sliding along an object using the trucks of a skateboard rather than the wheels. Grinds can be performed on any object narrow enough to fit between wheels and are often performed on the coping (edge) of a skate ramp, a purpose-built "grind box", step, ledge or horizontally-positioned pole.
Ollie
The rider begins the ollie by crouching and jumping directly upward. As the rider begins to leap, instead of lifting the feet from the board, he/she "pops" the tail by striking it against the ground, which raises board nose-first. Maintaining contact with the board, the rider lifts the front leg and bends the front ankle so that the outer or top side of the shoe slides towards the nose of the board. The friction between the shoe and the board's grip tape helps to guide and pull the board upward, while the rear foot only maintains slight contact with board to help guide it.
