I wanted these wedges to replace a pair of Carlos Santana's that I worn to death.  They look almost identical and when I first tried them on, I thought, "Perfect."  However, the first time I wore them the difference.  They "walk" funny, slide more than they should and therefore are not nearly as comfortable.  Also, because of the tendency for your foot to slide a bit they are not as stable and I found that I have to be more careful in them so that my feet don't slip to the side.  I don't know if I'm explaining this correctly, but the bottom line is they look great, but are really are just "ok."
