In water and on land, this sandal never stops performing!  It's cute AND functional... what more do you need?  I walk a lot of dogs in coastal Maine and am constantly splashing through puddles in the woods, through mud and over rocks and wading through the surf at the beach.  This sandal does it all, and does it comfortably, without rubbing or irritating my feet.  I am so impressed with the quality of this shoe.  I even wear it to work in a retail setting because it has amazing arch support for my high arches.  This is the ONLY sandal I can wear and not have pain in my feet and knees at the end of the day!  I would recommend this product and brand over and over; thank you, Keen, for your ingenuity!
