These are a great pair of lightly used Teva Proton Water Shoes. They were only ever used indoors - in the shallow end of a swimming pool as part of a water plyometrics workout. As such, the soles and insoles are in nearly like new condition - very clean, since they were only ever used in a chlorinated pool. That said, I think these would be awesome for outdoor use - they are well-built, and the soles have great grip.
High abrasion four-way stretch material in uppers helps keep these shoes securely on your feet, even underwater. Mesh uppers drain quickly and improve ventilation when you move between land and water. Wrapped outsole design prevents wear in high-abrasion areas and provides increased traction. Non marking Spider Rubber® outsoles provide just the right amount of grip and performance on river rocks or in tide pools.
