Get stoked on the Spitfire F4 Ishod Lock-in Classic Wheels, 54mm/93a from Stoked Ride Shop. These Ishod Wair pro model wheels pair Spitfire’s Formula Four Soft Slider 93a urethane with the custom Lock-In Classic shape for controllable slides, reliable grip, and all-terrain versatility. The 54mm size with a 33.6mm width and 19.5mm riding surface is the go-to mid-size for street and park, absorbing more impact and vibration than harder wheels while still delivering fast, lasting speed and unmatched flatspot resistance. Sold as a set of four in natural color.
Formula Four Soft Sliders and Lock-In Classic Shape
Spitfire Formula Four 93a Soft Sliders give a smooth, controllable slide with more consistent grip and less shock on rough ground or longer sessions. The high-rebound compound soaks up vibration and impact so you stay fresher while the legendary F4 urethane resists flat spots and holds its size and shape far longer than standard wheels. Ishod’s Lock-In Classic shape uses a medium-width asymmetrical profile with a straight-edge inner cut for better lock-in on grinds and rails, plus a classic rounded outer sidewall for versatile control on any terrain. At 54mm these wheels accelerate quickly, roll smooth, and stay predictable whether you’re technical street skating, hitting park transitions, or skating imperfect surfaces. The natural finish with Ishod graphics keeps the look clean while the performance does the talking.
