Blackwheels Sonic Rollers 40-43 (5902659841162)

Blackwheels Sonic roller skates have a quick size change mechanism, thanks to which you can change their length in a range of up to 3 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.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 roller skates is distinguished by careful workmanship.
