Between the 1980s and early 2000s having western clothing in Russia were not easy, and some well reconigzable western brands were considered as 'luxury brands'. One of them was Adidas.
As result many knock off and local copies emerged. And probably one of the most famous was the Mokba sneakers that you can seen on some old old Afghanistan war footage.
