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.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eAt 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.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eSpecs:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eDiameter: 56mm (35.3mm width)\u003c\/li\u003e\n\u003cli\u003eDurometer: 93a (marked \"93D\" in Spitfire's branding) — softer \"Soft Slider\"\u003c\/li\u003e\n\u003cli\u003eShape: Classic (round sidewalls, medium profile)\u003c\/li\u003e\n\u003cli\u003eFormula: Spitfire Formula Four (F4)\u003c\/li\u003e\n\u003cli\u003eColorway: White\u003c\/li\u003e\n\u003cli\u003eFeel: Softer, impact-absorbing, controllable slide, flat-spot resistant\u003c\/li\u003e\n\u003cli\u003eTerrain: Rough streets, transition, all-terrain\u003c\/li\u003e\n\u003cli\u003eBrand: Spitfire Wheels\u003c\/li\u003e\n\u003cli\u003eSold as: Set of 4\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003eNeed bearings, trucks, or hardware to finish a build?
