F4 Radial Full 93Du Soft Slide

Spitfire Formula Four 93D Radial Full wheels deliver the smooth roll of a softer compound combined with the slide performance of traditional hard urethane. The 93 Duro Formula Four urethane absorbs vibrations on rough terrain, preserves rolling speed, and offers high resistance against flatspots. Designed as Soft Sliders, they allow for controlled, predictable slides without sticking on uneven surfaces.

The Radial Full shape features a wide riding surface paired with rounded edges, maximizing stability on landings, high-speed control, and a solid lock-in on grinds. The 54 mm diameter provides a balanced setup for quick acceleration, proper clearance, and all-around capability across street and transition skating.
