This allows the skates to grow with your child and saves you from having to buy new skates every time their feet grow, while also providing your boy or girl with a long-lasting pair of skates. Our adjustment system utilizes a series of micro-adjustments rather than just locking in just at a full shoe size. These small adjustments allow you to fit the skates to the foot, which creates a custom, individualized fit for your child. This sort of customized sizing ensures that your child will have the most comfortable and supportive skating experience possible. The adjustment mechanism is also fully internal, so it is not visible and doesn't interfere with the classic look of these rink-ready skates! The boots are infused with bright sparkling glitter and are topped off with a thick, shimmering collar that sparkles in the light always catches the eye. They also come packaged with coordinating accessories; stunning glitter wheels, toe stops, and fashion laces. These awesome roller skates allow you to make the perfect fashion statement without even having to say a word. Once you are you done admiring your new skates, it will be time to take them for a spin and experience all of the Glitter Pops top-quality, high-performance features. These include smooth ABEC 5 bearings which allow the wheels to turn smoothly and provide a high quality roll for the best possible skating session. Similarly, our 58mm urethane wheels are the perfect mix bounce and grip, allowing the Glitter Pop to be used either indoors or outdoors with equal ease and enjoyment.
