These are Paul Smith dress shoes. They are not just ordinary leather shoes; they are stylish with threads that look like a mix of blue and purple, making them a fashionable pair. I purchased them at a vintage clothing store in the US, and I had the soles repaired, so I believe you can wear them for a long time to come. I usually wear a 27.5 cm in brands like NIKE, so I think someone who wears around that size would be able to wear these. I couldn't find the same product even when searching online, so these might be quite rare.
