Spitfire Wheels Formula Four Ishod Wair Lock In Classic (52mm/99d)

The Spitfire Formula Four Ishod Wair Lock-In Classic (52mm/99d) wheels are a dialed-in evolution of performance and precision, co-signed by one of the most technical and powerful skaters on the planet. The graphic showcases a clean, high-contrast layout: ISHOD in bold, black block letters sits across the top arc of the wheel, while SPITFIRE rides along the bottom. The center features a coiled black-and-red spiral graphic that locks the eye just as tightly as the wheel locks into rails. Flanking the spiral are the “99du” and “52mm” callouts—an honest nod to the specs, no fluff needed.

These wheels feature the Lock-In Classic Shape, a design personally developed by Ishod Wair. It sports an asymmetrical cut—a straight edge on the inside wall for better lock-in on grinds and ledges, and a rounded “Classic” outer sidewall for smooth release and all-terrain versatility. The result? A wheel that grips when you need control, and lets go when you want the slide. At 52mm diameter, with a 32.7mm width and an 18.6mm riding surface, these wheels hit a sweet spot for technical skating and park versatility.

Crafted from Formula Four Urethane, this wheel comes with all the durability and rebound you expect from Spitfire's flagship formula—flatspot resistance, lasting speed, and consistent grip/slide control across all surfaces. The 99a durometer ensures versatility across ledge spots, DIY setups, and smooth park concrete.

Ishod Wair, Thrasher’s 2013 SOTY and a Nike SB pro, has long been known for blending heavy control with fluid style. Whether it's switch flips down double sets or smooth nosegrinds through kinked rails, his skating demands gear that can handle serious abuse. His influence on the Lock-In Classic design makes this wheel a true skater-to-street creation—built to handle the same grind-to-slide precision that defines Ishod’s skating.

Backed by Spitfire Wheels, one of skateboarding’s most trusted urethane producers since 1987 under the Deluxe Distribution banner, this wheel continues the brand’s legacy of pushing progression while staying rooted in the raw grit of street skating. The Ishod Lock-In Classic isn't just a wheel—it’s a performance tool tuned for impact.
