Blackwheels Sonic Rollers 37-40

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.

Reliability of the running gear
Sonic Blackwheels inline skates are equipped with an aluminum runner, the ergonomics of which make skating easier. The aluminum used is light and gives the skid the necessary stiffness. The wheels are resistant to abrasion, but the high durability of the 5-spoke core and rim is also important. The wheels are mounted to the skid on ABEC-7 bearings, ensuring smooth rotation and long-lasting durability.

Careful workmanship from the best materials
The shell of the Sonic roller skates is made of a material that is resistant to mechanical damage that may occur when hitting hard elements. The shoe made of high-quality textile materials maintains thermal comfort during intense, long rides. Feet can breathe, and excess moisture is absorbed by the lining and leaks out thanks to the use of airy meshes. Each, even the smallest, element of the inline skates is distinguished by its careful workmanship.
