I did grow up on the eastern block (not Poland) and we also called Adidas shoes a type of sneakers that could be a different brand, it was the style that we called them like that. There were a lot more genericized trademarks/eponyms. I can think of two more: one for Blue Jeans which sounded something like "blu Gee" (from blue jeans) and "Jeep" which we called any car that looked like a Jeep but of any brand.
