I've been wearing Columbia sandals for several years now and where them every day, all year long.  They're comfortable, rugged, supportive and durable.  I've worn them hiking in Alaska, rock-climbing in the rockies and on the beach in Florida (where I live).  They typically last a little over a year before the straps start coming loose and get replaced with extra sandals I keep on hand.  I don't use any other brand and style and hopefully Columbia will keep making these for a long time.  I highly recommend them.
