These shoes were surprisingly awesome.  Took these to Costa Rica.  I had a pair of Keen water sport sandals.  I used these shoes way more than the sandals.  The mosquitoes would bit my feet through the webbing of the sandals.  They did not try to bite me nearly as much in these shoes.  The soles are very flexible.  You will feel every rock as you walk.  I did not go walk through much water, but the mesh and vents made it so my feet did not get sweaty at all.  The laces are adjustable, which is nice.

The one real downside of this shoe is the sole.  There are huge holes all over the bottom.  All kinds of rocks would get jammed inside the holes.  Sometimes really large rocks would get wedged and needed to be dug out with a knife.

I walked alot in these shoes.  I am estimating a good 15 miles or more over the course of 7 days.  The shoes did not tear and held up.  I scaled over volcanic rocks that were very sharp and hot from baking in the sun.  I did not feel the heat of the rocks, but I did feel the poke here and there.

If these had smaller holes in the sole and  a bit stiffer sole, that would be a huge improvement.
