I purchased these at a used clothing store. They are Nike ACG sneakers. They look similar to the classic Gore-Dome, but the sole is different, so I believe it's another model. Also, I couldn't find any information about the model number when I searched, so I think it's a pretty old model. The material is probably faux leather. The ACG logo on the back came off while I was walking. Since this model isn't very common and I haven't seen it before, I'm hesitant to sell it, so I've set the price a bit high. If you'd like to negotiate the price, please comment with your offer. I'll decide whether to sell it based on my mood at the time. I can also provide photos of me wearing them. Please note that I will prioritize the person who purchases the item, even if negotiations are ongoing. Condition: There are stains, tears, and odors.
