These are Giacometti loafers. They are made of sealskin and retail for around 110,000 yen. They have leather soles, so there is some wear and tear from use, but I don't think they are heavily worn down. The size is 44. The outsole is 29.8mm. The seller, who wears 28.5cm sneakers, found the fit to be just right, even with thick socks. There is an insole attached to the toe.
