These are nice lightweight sandals that are quite easy to put on. You can adjust the shock cord in only one place, which I didn't have to do by pulling it out of the box. I ran 8 miles cross country at the Olympics and they did very well. not wet yet, but get very little wet and mostly synthetic materials. I'm curious how they hold up; Given the light weight, I assume they can wear out quickly, but we'll see. Anyway, comfort, ease of use, good fit etc. all add up to 5 stars.
