Spitfire Antonio Durao Pro Formula Four Lock-Ins Skateboard Wheels

Wide - More traction and stability at high speed so you'll be less likely to slip out of your line.

Formula Four Urethane - Unmatched abrasion resistance for fewer flat spots. More controllable grip. Lasting speed no matter the terrain. Smooth anti-slick slide and a longer lasting size and shape.

Lock Ins Cut - Asymmetrically cut, you can get the benefits of conical outer walls while the inside wall is cut straight, giving you a flat surface to lock in your grinds.

99a - Offers more grip than harder wheels and more slide than softer wheels. Great for slick surfaces when you want more control.
