NIKE Air Thunder Max (apologies if this is incorrect, as it's an old product). I believe I purchased it around 2001, either in Japan or Australia. Please refer to the images to determine the size (probably around 27cm to 28cm). As it's an old product, there is some deterioration due to age. Please consider purchasing only if you fully understand that this is a vintage item. I don't have much detailed knowledge about the product, but please feel free to comment if you have any questions.
