It was the weirdest thing, the leather footbed eventually broke in this way that they became too slippery to wear without my feet sliding around in them. Very annoying and pretty dangerous if you were in uneven ground. I was in a very dry and arid climate most of the time, if that makes a difference. Best looking flip flops I ever had though and I would buy them again.

The leather ones in my experience wore out after a couple of years. That was a few years ago… sexy as hell though!
