The Microblade children's rollers by Rollerblade are made of high-quality materials and are ideal for daily use and exercise. These skates are size-adjustable, covering 4 sizes, allowing children to use the roller skates for more than one season. This is achieved with an easy-to-use expansion system that works with the push of a button to align the skates to the correct size. The support of the Junior Fit boot includes a mesh with seams for enhanced foot breathability and provides improved comfort and a good fit. The durable 3WD axle design lowers the center of gravity so that children can improve control, stability, and balance.
