These are cold-weather long boots from Koshin Rubber. They are the Sea-Lux Light SL-553AW, inner type. The color is navy. The size is M, which is 25.0cm to 25.5cm. I purchased these several years ago but never used them, so they have been stored for a long time. I checked them for the listing and found no noticeable stains or scratches, but there may be some overlooked deterioration due to aging. Please understand these points before purchasing. Also, please note that shipping will be on the weekend due to work commitments.
