A kickflip is a popular skateboarding trick where the rider performs a flip of the skateboard while in the air. To execute a kickflip, the skater uses their back foot to pop the tail of the board down and their front foot to slide up and off the edge, causing the board to spin 360 degrees along its axis. This trick is often considered a fundamental move in skateboarding and is commonly used in various combinations with other tricks. The kickflip was popularized by skateboarders like Tony Hawk and is a staple in many skateboarding videos and competitions.
