An ollie is a fundamental skateboarding trick where the rider leaps into the air while keeping the skateboard underneath them. This is achieved by popping the tail of the board off the ground with the back foot while simultaneously dragging the front foot up towards the nose of the board. The ollie allows skaters to jump over obstacles and perform various tricks. The ollie is not only essential for skateboarding but also serves as a foundation for other tricks, such as kickflips and grinds. Mastering the ollie can enhance a skater's overall skill and confidence on the board, making it a crucial technique for beginners and advanced riders alike.
