These are not made for creeks or beachs. I assume these are made for people in water sports that just deal with docks, boat decks, skidoos, and open waters since they are definitely not made for sand or gravel. I used once in creek and regreted since. The holes in the bottom of the soles suck in particulates every time you walk and pull them up into the insoles where they get stuck under the fine mesh. It is impossible to get this stuff out! So, once you use in gravel, you have this layer of rocks directly under the insoles that you can see quite well but can never remove. Same way with sand, except sand tends to comes out over time. On the good side, they are well made and very comfortable, and would love to use in the right conditions. For the price, I'll just continue to use my old sneakers for creek shoes and use these as comfortable dry lightweight sneakers, and take it as lesson learned.
