The way to tell if they're premium is by looking at the opening – single-layered or double-layered. These are Timberland boots. Worn for only one season. Size is 23.5. There's a black stain on the toe, but I think it can be cleaned off. I bought them for just under 30,000 yen. I have one small dog, so please refrain from purchasing if you are sensitive to that. #Timberland #DrMartens
