1.Twoinone skates: Adjustable multipurpose skates are different from conventional roller skates on the market. Hidden wheels can be hidden like ordinary trainers so you can have roller skates that can not only skate but also run. 2.Shoes: Multifunctional adjustable microfibre roller skates, rubber sole and PU wheel. We need to pay attention not only to the load capacity of the wheel, but also to the choice of the upper material to produce highquality roller shoes. 3.Foot protection: Adjustable multipurpose roller skates with traditional laces. As with trainers, you can adjust the laces to make them feel the most comfortable. Unique invisible button design to prevent accidental opening: There is a button on the back of the shoe. Press it and the wheel will open. Press and hold the button to push the roller into the base plate and release. 4.Mechanical Test: Multifunctional adjustable skates have been tested and redesigned. Depending on the mechanical design, the heel support provides additional cushioning and a high factor making it ideal for beginners.
