In the category of foam sandals, these are certainly the best I've ever owned.  They're durable, and they've lasted me over 3 years at this point with little sign of structural wear.  They're extraordinarily comfortable right out of the box - no breaking in period necessary.  The fabric toe strap is one of the softest and most comfortable I've ever experienced, with no stitching or fabric folds to rub or irritate your foot.  I can't recommend these enough!
