Thank you for viewing. This is a Sock-On Sandals Comfort, purchased a few years ago from the Montbell online shop. It can be used barefoot or with socks. I use a size S, which is one size smaller, so I bought a size M (24.5~26.5cm) for my husband, but he didn't like it, and it ended up sitting unused after being worn a few times at the entrance. I washed it before listing it, and wiped it with alcohol, so there may be some slight color fading. This is a discontinued model, so I hope someone looking for it can make use of it. * Although it is still a clean item, it has been stored at home, so please refrain from purchasing if you are nervous about this. * Please feel free to ask any questions if there are any unclear points, items that are difficult to understand from the images, or areas of concern. * Images 6, 7, and 8 are reference images. #Montbell #mont-bell #Stream #Festival #Resort #Socks #Sandals #Socks
