Spitfire Wheels Radials Formula Four Soft Sliders 56mm 93 duro is a premium all-terrain wheel set made for skaters who want a smoother ride with controlled sliding, without losing that fast Spitfire feel. The Radial shape gives you a wider, more stable riding surface, while the Soft Sliders Formula Four urethane in 93 duro adds extra grip and comfort on rougher ground. With a 56mm diameter, these wheels hold speed well and roll over cracks more easily, making them ideal for fast street sessions, cruising between spots, and skateparks where flow and control matter.

Performance & ride feel

These wheels feel smooth, stable, and confidence-inspiring — especially on crusty streets where harder wheels tend to chatter. The 93 duro urethane adds comfort and grip, while still maintaining a fast roll and consistent performance. Slides are easier to control and feel more “buttery” than standard hard Formula Four wheels, making them a great choice for skaters who want to slide more without losing stability or speed.

• Smoother roll with reduced vibration on rough ground

• Strong stability from the Radial shape

• Easy, controlled slides with predictable release

• Great speed retention with 56mm sizing

• Perfect for all-terrain street missions and flowing park lines

How does it feel underfoot? Smooth, stable, and grippy with controlled, easy slides.
Is it best for street, park, transition, or all-terrain? All-terrain — especially good for rough street skating and parks where you want comfort plus slide control.
