Slides and grinds involve getting the board up on some type of ledge, [[Grind rail|rail]], or coping and sliding or grinding along the board or trucks, respectively. When it is primarily the board which is contacting the edge, it is called a slide; when it is the truck, it is a grind. Grinding and sliding skateboards started with sliding the board on parking blocks and curbs, then extended to using the coping on swimming pools, then stairway [[handrail]]s, and has now been expanded to include almost every possible type of edge. Grinds and slides on street environments were brought to mainstream skateboarding by professional skateboarders [[Natas Kaupas]] and [[Mark Gonzales]].
