I bought them as waterproof shoes, so I haven't used them much for running, but for walks, etc. I think I've used them for about 20 kilometers. Since they are used, there is some wear and slight scuffing on the outsole, so please purchase only if you can accept this. How about using them for running during the rainy season?
