I've only had the sandals for a week and bought them for long country walks with my dog. They are ideal for use in rivers when going over rugged, uneven, wooded terrain. Lightweight, comfortable and durable, they easily withstand all the conditions I test them in. I found them to be true to size too, I bought a 9•5 but bought a 10. There is room if I were a 10 but the straps mean that when adjusted they fit well even with my wide feet. I am very happy with the sandals and would buy a pair for my partner. The only reason I didn't was because she said she was clumsy and wanted closed sandals so she didn't bruise her toe. Excellent purchase.
