These roller skates adjust to fit shoe sizes from 3 to 6 and 12 to 2, so they can grow with your child and stay comfortable through plenty of outdoor fun. The 54x32mm PU wheels feature a subtle glitter detail that adds a playful touch as they roll. For a smooth, stable ride, the skates include ABEC 5 bearings designed to help young skaters feel secure. Built from durable PVC in the outsole, main body, and tongue, they hold up well to regular use. Inside, a soft foam lining wraps around the foot for lasting comfort, helping keep little skaters happy and supported during play.
