This is GU's real leather series. The most popular size is 26cm. My usual shoe size is 27cm in NIKE sneakers, 26.5cm for running and exercise shoes, and 26cm for business shoes (3E). Please use this as a reference. The fit of these shoes was much better than the real leather side gore boots released after this product. Currently, GU only sells derby shoes in real leather, so wouldn't these be quite rare? I've worn them a few times, but I haven't had much opportunity to wear them. After cleaning the uppers with leather cream, I wanted to give them a luxurious look, so I gave the toes a shine finish and stored them. Those who don't like the shine on the toes can easily remove it with a shoe cleaner. The side gore hasn't stretched and still has its firmness. As you can see in the images, the rubber soles have some scuffing, but they are not gouged. I think they are in good condition overall, but please refrain from purchasing if you are very particular. I will ship them in another shoe box. Due to the size, the shipping cost will be high, so I cannot offer much of a discount, so please understand. I will ship via Yu-Pack.
