I have owned the version 4 of these shoes for one year. They have gotten moderate usage. Part of the grip on the sole has peeled off. A small hole has been worn away on the tongue. Parts of the shoe might be waterproof, but after running in wet grass my socks are wet, so water still gets in somewhere. I wonder if the toe of the shoe is coming away too, but for now it is holding. I like the straps for pulling the shoes on. They work well. The shoes are quite comfortable.
