I got these to replace my very worn Teva Mush flip flops.  Although I loved the Mush flip flops, I love these, too.  I did like how soft the Mush flip flops were, but that made the material more vulnerable, thus making my feet more vulnerable.  I like how the Mandalyn flip flops do not stay bent or curved after a while.  And although they do not mold to your feet quite the same as the Mush ones, the firmness gives good support.  I guess it's one of those personal preference things.  Do you prefer a soft, squishy bed, or a firm one?  I prefer a firm one.  These flip flops are much firmer.  I can walk around in these flip flops for hours at a time without any pain.  They've held up much better than my Mush ones did, and it looks as though they've still got lots of life left in them, even after regular wear for over a year.
