Good quality, One of it's strengths is multiple adjustable velcro straps.  This could also be a weakness, it was hard to get them adjusted comfortably, and I did get a small blister the first time I wore them, but only on the left foot.  Take time to adjust and re-adjust before wearing for a full day like I did!  Over time, I have found that the adjustability of these sandals is a detriment.  Even thought they are velcro, under constant stress, the buckles will relax and loosen, and will cause blisters if not addressed with retightening.  Unlike my other high-quality sandals, these have not broken in and molded to my foot as they should.  While they fit well at first, they now sometime seem loose and wishy washy as I walk.
