I?ve only had them a few days so I hope I?m not speaking too soon, but they appear to be perfect. Ideal as a cross between outdoor shoes and slippers. Bought as a christmas gift and were completely broken by mid January. But wow wow wow, I?m shocked that $20 headphones could survive that. The grip on the bottom is amazing. When they slide out enough, the bar becomes unbalanced which is not only super annoying, it has the potential to lead to injury to me or to bystanders if the bar became enough unbalanced that the weights were to slide off the end (thats not happened in years, but it has happened). Hopefully that solves the problem. It?s Case-Mate, and they always make quality cases. This is my 4th pair of Fitflops and they are as good as ever. Not on the dividers, not on the sides, not on the bottom.
