Adults and youth with growing feet will love the new Velocity by Roller Derby. The inline skates adjust from adult size 7to 10 at the push of a button. The double buckle closure makes the skates easy to put on and take off, and provide a solid level of comfort and support. The boot and liner have extra ventilation to keep feet cool on long sessions and are designed to provide stability by locking the heel in place. The ultra-lightweight frame is great for beginner to intermediate skaters who want more agility and durability. These skates are breezy and fast, featuring smooth-rolling 72mm urethane Speed Formula wheels that absorb vibrations in the road and have great grip for turning tight corners. They are loaded with high-end Silver-5 speed rated bearings which are built for speed. Use them indoors or outdoors, on rinks, roads, sidewalks or floors. These adjustable inline skates for teens, children, and adults fit true to adult shoe sizes 7-10.
