I have worn Teva Flip Flops for 8 years.  These are lower quality than in the past.  Almost a plastic-y feel to the sole.  They are not as thick as my old worn out ones.  Guess they are just making them cheaper...though they are more expensive than they used to be!  Sad, actually.  I always bought these for the arch support, but I'm thinking there should be a better flip flop out there somewhere...
