Expanding across shoe sizes 2 to 5 at the press of one button, these quad roller skates follow kids aged 7-9 through multiple shoe sizes. Motion-activated wheels glow without batteries, while 82A polyurethane rollers and Abec-7 bearings smooth out rink floors and driveway sessions. Laces, adjustable buckles, and hook-and-loop straps triple-secure each ankle, and the reinforced brake steadies every stop.
