Quiet, smooth roll: High-quality PU wheels combined with ABEC-7 bearings deliver a quiet, efficient ride on both indoor and outdoor surfaces. The materials are tear-resistant and built for long-term use, reducing noise and wear during regular skating. Visible and safe in low light: Eight illuminated wheels made from wear-resistant PU rubber automatically emit coloured light while rolling, increasing visibility and adding a fun visual effect during use. Easy, precise fit: A push-button adjustment system lets you change the fit quickly and reliably by pressing the button. This makes the skates adaptable to more foot shapes and provides a consistent, comfortable fit as feet change. Comfortable all day: Boots use soft, breathable and durable materials with mesh panels that help absorb moisture and keep feet drier and more comfortable during extended wear, reducing uncomfortable heat in warm conditions. Built for varied surfaces and uses: Durable construction and wear-resistant PU wheels make these skates suitable for indoor rinks, smooth pavement, and other common outdoor surfaces without sacrificing ride quality.
