This is a slimmer version than the Classic Mini, with an inner zipper for a more snug fit. Recommended for those who want the benefits of UGG boots without the bulky look. I bought these in Hawaii, and I remember being told they weren't available in Japan at the time. Also, the gray color was hard to find, and this was the last one in stock. Personally, I find them convenient to use, like wearing mid-cut shoes. The gray color goes well with both muted colors and monotone outfits, making them easy to coordinate. I don't think I've ever seen anyone else wearing the same zippered style. First photo... The color is a close match. Second and third photos... They give a good idea of what they look like when worn. My lifestyle has changed, and I mostly wear loafers now, so I'm selling these. I've always taken good care of them, having them professionally cleaned, so I'd like to pass them on to someone who will cherish them. Size: I usually wear a 24.5, but I got these a bit bigger so I could wear thick socks. Please refer to the 8th photo for the size details, which I found online.
