The Rollerblade Solo Trooper Aggressive Skates are perfect for the technical freestyle roller. They feature a molded shell with a new street formula soul plate material with a 45 degree shock absorber that will allow you to take bumps comfortably. This lightweight skate will keep rolling and grinding because the balance is low, this way you have control and flex during your jumps and while locking onto the rails. There is one 60mm wheel in the front and one in the back, in the middle are the two smaller 42mm wheels that will keep you rolling and on the rails as needed. The shell is molded and tough and can take a beating, so if you are hard on your skates, this pair is the ones to own. The secure and snug fit is due to the cuff strap, the 45 degree power strap and the lace combination. The SG5 bearings will keep you rolling with a smooth ride and speed you need to get up in the air. It doesn't matter if you are a beginner or more advanced the Solo Trooper has style and will bring you confidence.
