Some place in the adverts it says these are not technical hiking shoes. It should say, technically, these are not hiking shoes. The HUGE problem is that the keeper that is supposed to work to tie the moveable heel pad in a forward position doesn't work. It's a cheap imitation. So, you can pull the tab tight to lock your foot in for hiking, or just walking, and after 5 steps the strap just slips right through. Try walking and bending down every 5 steps to tighten a strap. Not even good enough for a walk in the park.
So they shed water. So does any shoe made from synthetic materials and mesh. But these use real hard plastic in the lacing area, so if it bears down on a sensitive part of your foot (especially since you won't be wearing socks in water mode) your feet are toast. No amount of break-in breaks in plastic.
I just spent 4 days on the Colorado River and a 9-mile hike out of the Grand Canyon. I'm throwing the shoes away!
