well, they're so dang cheap... I could see wearing them to the beach - I probably wouldn't go to the trouble of getting them unless you have a lot of other things in your shopping cart at delia's.

they're just okay.. personally, I wouldn't get them, instead, I'd spend that $4 towards some other sandals that I'd wear more often. I have often made the mistake of buying something that is just "okay" because it was too cheap to pass up, only to later regret it because I never ended up wearing/using the item. If you will wear them a lot, then go for it.
