Spitfire's Formula Four urethane gives unmatched abrasion resistance for fewer flat spots and smooth, anti-stick sliding. You get more controllable grip, and lasting speed.
The OG Classic shape has a conical profile, with a wide contact patch, enough curve for good slides, and flatish sides for locking in.
Pack of four.
