I've been looking for shoes to wear around the water that wouldn't fall off easily, but wouldn't leave me with wet feet all day. The first real test I gave these shoes was doing the Outdoor Adventure in Puerto Vallarta. You walk a lot, do zip lines, and rappel by a waterfall. These shoes gripped the rocks for rappelling, were comfortable for walking up the mountains, and didn't leave me with pruney feet after we did the zip lines down into a pool of water. I tried Chaco's, but I have pretty flat feet so the arch killed me. These are perfect. Now I wear them outside for yard work and around the house when I'm cleaning because my feet don't get hot. I'll be wearing them around the lake and when we go canoeing next week and I don't have to worry about my feet being comfortable. I recommend these to EVERYONE!!
