These sandals are very comfortable and are snug enough to provide grip on rocks and loose ground, even in creek beds. I first used these sandals on a 3 day hike and it was the only 'shoe' I took with me. We braved the torrential rain, crossed a turbulent stream (i.e. almost a river) over a dozen times and walked at least 15 miles. It was nice not having to worry about my sandals getting wet or dry while hiking. My feet were wet 90% of this trip but the sandals were comfortable the whole time.
