The Slime Balls Vomit Mini 56mm 97a Skateboard Wheels. A modern twist on the classic Slime Balls. Perfect street wheel for rougher spots yet it isn't a totally soft wheel. Will still slide for tricks easily. These wheels come in a classic 80s shape, slimmed down for the modern skateboarder. The 97a durometer will give you a bit more grip in those super slick freshly painted surfaces and will take some of the rattles out of rougher parks. A great all-round wheel to hit all the transition you can find
