Very disappointing.  If you wear the shoe longer than 10 minutes they turn your feet blue since the interior bleeds onto your foot if you sweat at all or get it wet as someone else mentioned.  Also, very uncomfortable and incredibly poor quality.  As everyone else mentioned, can't believe Patagonia has their name not this shoe.  Other Patagonia shoe i have that's not available anymore is much better quality so don't know what happened here.
