The audio quality is alright out of the box with plenty of bass, but can sound a lot better with a little EQ tweaking. My first time trying out the cloud version and I really do love them. Have not try walking into water yet. They are firm enough so you do not wobble in them while walking. Easy to attach. The Velcro feels very secure and lowered wind noise a bit. I like how the author did all this fun stuff . But I?m returning mine because of the bad zippers. Great new style and excellent quality. Most importantly, these shoes are extremely comfortable and well-made!
