Love them.  Could have potential for a little pinching on the inside of the foot where the strap is, but I got them for like $21 when they were on sale (I think they're now $50), therefore, I am totally willing to experiment with some padding in that spot if it proves to be a problem.  Also, I commonly have trouble with my heel slipping out of slingbacks, but these are adjustable, and no problem.  They look great on -- very classic.
