The BlackWheels Playful is a recreational roller skate designed primarily for younger users. As you know, it can sometimes take longer for a child to learn how to skate, and as a result, the skates may turn out to be too small for further use after just one season. With the BlackWheels Playful, you don't have to worry about that, as they feature a special One Step Adjustment quick adjustment system. This allows the length of the skate shell to be changed in four steps without any tools - at the push of a button. The skates literally "grow" with your child.
