I had broken my foot and needed a pair of sandals with good arch support--and I lucked out when I found these.  Interestingly, the arch support is so expertly contoured that it doesn't feel like a support, which initially made me skeptical.  However, when I wear them (now, for instance) I am pain free, which certainly isn't the case with other sandals (or even shoes, unless I add an arch support insert).  They are also very rugged, easily washed, very adjustable with the Velcro band on top (though I haven't needed to adjust them), and darn, they look good, too (I bought them on sale and Chocolate was the only option in my size, but they turned out to be the best looking sandals I've ever had).  Oakley always seems to get it just right, and these sandals have greatly accelerated my recovery.
