We go boating a lot and these are great for when I'm putting our boat in the water. Those tiny rocks and pebbles can be super sharp but I never feel a single one of them.

These do drain well and are really comfortable but the bottoms can still be slippery if you're walking on wet rocks. Just be careful!

They work great in water but I also like to wear em on hotter days if we're walking around and regular sandals will let too much debris get in.
