Using these Yvolution Twista Skates is a breeze. First, make sure your child's feet are the right size, between 7J and 11J. Put the skates on your child like regular shoes. When your child is just starting out, keep the skates in learner mode. As they gain more confidence, press the button to switch to inline mode, no tools needed. For safety, always ensure your child wears protective gear like helmets and knee - pads. The skates are suitable for kids aged 2 and above, and the maximum weight the skates can handle is 20kg. To keep the skates in good condition, wipe them down after each use to remove dirt and debris. Check the wheels regularly, and if they seem worn, consider getting them replaced. That's it - now your child is ready to have a great time skating!
