Roces Jokey 3.0 Roller Skates for Boys in black and blue. Roces roller skates are designed for children and teenagers for recreational skating. The construction and frame of the shoe, supported by the Growth Compensator system, allow for size adjustment with a button located under the heel. The outer shoe is made of high-quality, fiberglass-reinforced polypropylene. The frame is made from durable material. The Easy-Entry System technology makes putting on and taking off the skates easier. The 3-stage closure stabilizes the foot and prevents accidents caused by unfastening. An inner shoe with an anatomical insole features a Cool Breathe system that supports foot ventilation. The so-called Rubber Wheels are mounted on ABEC-3 bearings, which are not the slowest but also do not allow for the development of dizzying speeds.
