I decided to keep them.  I couldn't decide at first because they're not that exciting and they're not that cheap, but after trying them on and realizing that they're comfortable and they go with pretty much anything, I've found myself wearing them often.  What they lack in character they make up for in versatility and comfort.  They feel different than the sandals I've been wearing - I guess I've gotten used to leather-sole wedges and these feel a lot more rubbery to walk in, but still comfortable.  Not much arch support and it is true, the front strap is loose, but it doesn't seem to affect the fit much and there's definitely no rubbing.  One thing I'll say for them - they're quiet!  They were comfortable even at first wear and they do have a classic look to them, even if they're a little boring.
