Formula Four 97 Duro Radial Full Skateboard Wheels

The Design: Built with a maximum-width contact patch but finished with smooth, round shoulders.

The Performance: Because the edges are round, they are highly versatile. They roll effortlessly over coping, curb angles, and rough terrain without catching. They offer predictable, responsive sliding because there is no sharp shoulder to abruptly catch the ground or a ledge.

Best For: Skaters who want maximum stability and a wide riding surface but still prefer the smooth sliding and flip-trick scoop of a classic round wheel.
