Thanks for posting your interest to the wishing well.  We will keep this in mind for future projects.  I know none of these are exactly what you looking for, but there are quite a few no heel to low heel boot options.  I've listed a few of my favorites just in case you might have missed seeing any of these that could possibly have the heel hidden.
