I love these. It is about time for me to buy another pair or two.  I wore them often for 6+ months. I did have some threading come free after about 6 months and stitching come free, but I did wear them a lot so that is probably expected.  I am 6'7' 250lbs and after 6 months of almost daily wearing them, the tread and cushion has held up.  The bottle opener at the bottom is a conversation starter and good party trick, though few people want anyone taking off their flip flop to open a beer. However, the metal in the middle of the shoe actually provides some strength to the shoe and support for people with a high arch like me.
