A trick is often performed with the skater's front facing the ramp or obstacle. A Goofy-foot is a skating posture in which the right foot is the lead foot as you spin the front of your body towards the direction you're riding. Grip tape is a piece of adhesive-backed sandpaper that is applied to the top of the board to give grip. Skaters use different words to describe specific tricks including ollie, kickflip, and nosegrind. There are many types of tricks that can be done with a skateboard. There is something for everyone to try their hand at; from simple flips to complex jumps. The most basic type of trick is called a grind. This involves walking or rolling the board along a surface until it is lifted up onto its end. From here, you can put it in reverse, which will roll back down the surface, or keep going in the same direction for a flip! Other common tricks include: ollies, which are small kicks where the board leaps into the air without touching the ground; manual lips, where the rider does not use their hands but instead spreads their legs to slide along rails or other objects; kicktails, which are long boards with a separate section attached to the bottom; and flip tricks, which are similar to grinds except that the board is flipped over before it rolls back down. There are also several types of slides, such as banana, half-pipe, and wall rides.
