Blackwheels Sonic Rollers 33-36

Blackwheels Sonic roller skates have a quick size change mechanism, thanks to which you can change their length in a range of up to 4 sizes without the use of tools. At first glance, there is nothing extraordinary about it, because adjustable roller skates have been popular for many years. However, Sonic are special - their structure has been designed so that when extended to the maximum length, the rollers retain their strength and stability.
In the case of people starting their adventure with roller skates, the most depends on the first impression. If they fit properly and develop good skating skills quickly, roller skating will become one of their favorite outdoor activities. In the case of advanced ones, a good fit is crucial. Sonic Blackwheels skates have an anatomically shaped shoe that perfectly adapts to the foot. The lacing of the rollers and the buckle fastening the shell collar guarantee stabilization of the ankle joint, and the strap placed at the right angle presses and stabilizes the heel.
