Reef Men's Smoothy Flip Flop

I've gone thorough 5 pairs of these over the years. I wore them practically every day at university (except in winter). They are comfy and soft enough to wear all day. The only thing I noticed about them is that they squeak really loud when new. I noticed that with my first pair. By the time I got to class one morning the squeak was driving me nuts, so I kicked them off into my locker and went around all day on my toes. The squeak disappears fast though, once the foam wears smooth. Each pair of mine has lasted at least 2 years. I haven't had to toss them until the foam wore right through to the sole.
