The Trina 3 in 1 children's inline skates are not only adjustable in size but also allow kids to easily learn how to skate. The wheels can be mounted in three different configurations. Initially, the wheels can be set up for beginners like roller skates, meaning there are two wheels side by side at both the front and back. Then, the front two wheels can be mounted in a line while the back wheels remain in their original position. This way, children can gradually get used to the feeling of inline skating until eventually all three wheels can be aligned in a row. For a secure fit, they feature laces, a Velcro strap, and a double-secured plastic buckle. The skates are suitable for a maximum weight of 60 kg. Features: Trina 3 in 1 children's inline skates, size S 30-33 adjustable, PU wheels, 608ZB bearing.
