SPITFIRE FORMULA FOUR APRIL YUTO BLACK CONICAL FULL 53MM 99D (Set of 4)

The Spitfire x April Yuto Horigome wheels put a two-time Olympic gold medalist's signature under your feet. This official collaboration pairs Yuto's exclusive graphics — the most decorated name in competitive street skating — with Spitfire's industry-leading Formula Four urethane. F4 is the pro standard: more speed and control on every surface, unmatched flat-spot resistance, a smooth anti-stick slide, and a high-rebound compound that keeps its shape and speed long after cheaper wheels mush out. Hand-poured and engineered in San Francisco, CA, it's a wheel that genuinely competes with anything on the market.

At 53mm, these run the Conical Full shape — one of the most popular shapes going. It combines a wide riding surface for stability and control with reinforced, cut-in sidewalls that lock in on ledges and rails while trimming weight for a lighter, more responsive feel. The smaller 53mm diameter sits low and light, making it an ideal technical street size for flip tricks, ledges, and manuals. The 99a durometer hits the versatile sweet spot — quick and slidey like a harder wheel, but forgiving enough for everyday pavement. Finished in a sharp black colorway. Sold as a set of four.
