Covering shoe sizes 8.5 to 11, these adjustable quad skates fit teens aged 13 and up whose feet have nearly finished growing. Self-powered light-up wheels glow brighter the faster they spin, with no batteries to replace. The 82A polyurethane wheels ride smoothly on rink floors and outdoor paths, Abec-7 bearings keep the roll consistent, and the buckle, strap, and lace system anchors each ankle.
