The skates have thicker aluminum alloy frames and stronger plastic frames, which significantly improve the strength. They are lighter than the metal steel blade frames, combining lightness with high strength. The shoe shell is made of PE impact-resistant material, and the entire soft upper is combined with breathable mesh, reflective PU leather, and printing. The soft upper provides better comfort, and the addition of many breathable mesh allows heat in the shoe to be discharged in time, making it easier to manage and more conducive to sports! The wheels are high-elastic and wear-resistant PU infused color wheels (real Guangdong PU wheels). PU wheels are commonly known as soft wheels, not hard plastic wheels with no elasticity. They have good elasticity and strong traction! The bearings are carbon steel ABEC-7 professional bearings, the best bearings to ensure smooth and smooth! The skates are all single brakes with one brake on the right foot. Because the braking skill is to support the body weight with the left foot and brake with the right foot, there is only one brake.
