Spitfire F4 Lock-Ins Wheels

Medium - Your classic wheel shape, versatile all-around wheel for street/park skating.

Smooth - Smooth wheels come with a shiny coating on the riding surface that feels grippy at first, but wears away quickly.

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.
