Supporting bigger kids and young teens, these expandable quad roller skates adjust across sizes 6 to 9 with a simple one-button system for ages 9-14. The motion-activated Led wheels shine brighter with speed and recharge themselves through movement. Wear-resistant 82A polyurethane wheels, premium Abec-7 bearings, a reinforced brake, and layered buckle-strap-lace closures keep advancing skaters secure.
