These wheels feature a shiny coating on the riding surface that provides initial grip but wears down quickly. With a versatile medium profile, these wheels are suitable for street and park skating. Made with Formula Four Urethane, they offer unmatched abrasion resistance for fewer flat spots, as well as controllable grip and lasting speed on any terrain. The classic shape is designed and shaped by pro skaters. With a durometer of 93a, these wheels are ideal for beginners until they gain enough control for harder durometers, and also work well in rough pools.
