When you watch your child roll down the driveway for the first time on her new pair of Bladerunner Phoenix Inline Skates, you'll be happy to know that these comfortable pair of skates will help them improve their skating skills and will last them quite a while. These adjustable skates allow you to increase the size by the quick push of a button. They can move up to 4 sizes so you'll be saving some money because you won't have to buy a new pair of skates every year to accommodate your child's growing feet. To keep them locked in and secure, there is a buckle, power strap and lace closure. This closure system also ensures that they have stability and control in each stride. Wallet-friendly while still boasting performance and style, every child will love skating around the neighborhood in their own Bladerunner Phoenix Inline Skates.
