The Spitfire Formula Four 93a wheels are Spitfire's "Soft Sliders" — a softer take on their legendary F4 urethane that gives you comfort and control without giving up performance. The 93a durometer pairs a softer duro with F4's high-rebound compound, so it absorbs more impact and vibration (easier on your body over long sessions), holds speed through even the roughest terrain, and delivers a smooth, controllable, consistent slide with reliable grip. Best of all, it keeps Formula Four's unmatched flat-spot resistance — so unlike typical soft wheels, these won't chew up or lose their shape.
At 56mm in the versatile Classic shape — round sidewalls and a medium profile built for control in every situation — they're a great choice for rougher pavement, transition, longer sessions, and skaters who want a more forgiving ride while still skating properly (not just cruising). Finished in a clean white urethane. Sold as a set of four.
