Like several other reviewers as soon as the shoes got wet the insoles came loose and wadded up under my feet.  When I removed the shoe I saw all that was hold the insole to the sole was a small area at the heel.  These were the only shoes I had with me to use at the beach so no insole was better than one that made walking impossible.  I wore them since I had no other choice.  I am here now trying to find something I can wear the next time I go to the beach....hopefully one that lasts.
