Softer Formula Four Classics that soak up rough ground, slide long, and still feel like a proper street wheel under your feet.

The Spitfire F4 93 Classic Skate Wheels (often called “Soft Sliders”) are built for skaters who want the control and shape of a traditional hard wheel, but with a slightly softer feel for rougher streets and crusty parks. Using Spitfire’s Formula Four urethane in a 93 durometer, they roll longer than a standard 99 while taking the sting out of cracks and coarse concrete, making them perfect for spot hunting, filming, or daily pushing on less-than-perfect terrain. The Classic shape keeps things familiar and versatile, with a round profile and balanced width that works for ledges, rails, and transition, just with a touch more grip and a super controllable, “buttery” slide when you kick them out. If you like the idea of a hybrid between cruiser comfort and proper street performance, these sit right in that pocket.

• 93a Soft Slider formula: Softer-than-standard 93 durometer Formula Four for smoother roll and extra grip on rough ground while still behaving like a street wheel.
• Formula Four performance: Same F4 DNA with strong flat-spot resistance, long-lasting shape, and a predictable, controllable slide.
• Classic all-round shape: Proven round profile that feels at home on ledges, rails, and transition for mixed street and park skating.
• Sizes for real-world terrain: Commonly offered around 52–56 mm in the Classic shape, giving options from more technical setups through to faster, rough-street friendly sizes.
