Black (faux) Alligator Skin Boots with Gold Chain

I purchased these years ago (around 2018) and hadn’t worn them much. Beyond creasing and minor scuff marks, the boots are in excellent condition. The zipper pulls up and down smoothly, the interior of the shoe has no damage, and neither does the bottoms/soles. The boot strangely says it’s a size 8 US but also lists itself as a size 41 EU, which is a 9.5 US. It also fits like a 9.5 US. Most likely a manufacturing error.
