- Material and construction: The multi-functional adjustable roller skates use a microfibre upper, a rubber sole, and PU wheels. The design emphasizes wheel load capacity and upper material quality to deliver durable, high-quality skates. - 2 in 1 design: These are skateboard shoes trainers with hidden wheels in the sole. To switch to skating mode, simply turn the heel switch to reveal the wheel. You can add these unique shoes to your friend's glider team. - Fit and foot protection: The skates use conventional laces for an adjustable, comfortable fit. Tighten the laces for a snug feel when skating to help safety. - Safe wheel deployment: The wheel activation uses an invisible button to prevent accidental opening. There is a button on the back of the shoe. Press it to open the wheel. To retract, press and hold the button, push the wheel into the base plate, then release. Use scenarios: - Campus or city use: walk normally when not skating, then switch to the hidden-wheel mode for a quick glide during short trips. - Social skating: wear with friends, add these shoes to a glider team for group outings or casual performances. - Indoor or outdoor practice: use the adjustable laces for a secure fit and deploy the wheel only when needed for controlled, light-skate sessions.
