These were a bargain at around $15, but I am still on the fence.  They are the right length but seem to be too "short" in the height... and I have very flat and narrow feet!  Over time I think they will loosen up but they do put a lot of pressure across the instep right now.  One thing I do notice is that the top of the sandal seems to sit pretty far back (towards the ankle) when compared to other thong/flip-flop style sandals.  I will continue wearing them but I do think they'll take some time to break in to where I really like them!

*Updated 8/29* I still am not crazy about these. The foot bed is comfortable but the top is still too tight and unforgiving, despite wearing them every day for a week.  I have noticed too that they are very squeaky. These might get demoted to being garden sandals, which I think would suit them well..
