Snowboarding is a sport that involves descending a slope that is covered with snow on a snowboard attached to a rider's feet using a special boot set into a flexible mounted binding. The development of snowboarding was inspired by skateboarding, surfing and skiing. It was developed in the U.S.A. in the 1960s and the 1970s and became a Winter Olympic Sport in 1998.
In freestyle, the rider uses manmade terrain features such as rails, jumps, boxes, and innumerable other innovative features to perform tricks on. The term "box" refers to an object with a slick top, usually of polyethylene(HDPE), that the rider can slide on with the base of their board. Like all freestyle features, boxes come in a variety of shapes, sizes, and difficulty levels. The intent of freestyle is to use these terrain features to perform a number of aerial or jib tricks. The term "jib" refers to the rider doing a slide or press on an object not made of snow. This most commonly refers to tricks done on boxes, rails, or even trees.
The equipment used in freestyle is usually a soft boot with a twin tipped board for better balance while riding regular or switch, though freeride equipment is often used successfully. The most common binding stance used in freestyle is called "duck foot", in which the trailing foot has a negative degree of arc setup while the leading foot is in the positive range i.e. +12°/-9°. Freestyle riders who specialize in jibbing often use boards that are shorter than usual, with softer flex and filed down edges. Shorter length enables the board to be rotated faster, and a softer flex requires less energy for a rider to press a feature. Reverse camber boards, or better known as rocker boards, are most often used as freestyle boards due to their softer flex and inverted 'camber' design.Pressing refers to a type of jib where the rider leans heavily toward the nose or tail of their board- causing the opposite end of their board to lift off of the feature they are sliding on.
Freestyle also includes halfpipe tricks. A halfpipe (or "pipe") is a trench-like half-tube made of snow. Tricks performed may be rotations such as a 360° (a full turn) in the air, or an off-axis spin like a "McTwist". Tricks can be modified while hitting different features. Riders will also usually perform a combination of board grabs and nuts.
