"Easy to put on and take off, and excellent walkability." The opening uses chloroprene, also used in wetsuits, making it easy to put on and take off, and providing a snug fit. Easier to wear than rain boots. Size: I usually wear 27.5 cm, and this size is fine. I bought these new for the rainy season, but I hardly used them. Because of the low frequency of use, I think they are in a clean condition, but please be sure to look at the images and make your purchase decision. Please consider only if you understand that these have been stored at home. No claims and no returns. Please refrain from price negotiations.
