The boot shell extends over 4 shoe sizes, so the skates will grow with the size of the feet of your child. The boot is made with a durable composite material with a high resistance to abrasions. The kids Jet inliners from Powerslide are high-end size-adjustable skates that will take over where your kid's training skates no longer can keep up. The setup is low weight, three-wheeled and mounted up with fast Wicked ABEC 7 bearings. All working together in order to provide a pair of skates that are easy to gain speed on whilst the manoeuvring capabilities are second to none.
