yes Bob, now add a high heel, and this is a pump! now you you understand why your wife used to complain about her shoes all the time, and slip them off as soon as she sat down.. and remember she was expected to dance (backwards,no less) and look elegant in them!

actually, i always think a mary-jane has a strap across the instep (i have 2 pairs of mary-janes) and a dancing shoe, is a mary-jane with a low (high) heel-- about 1.5 inches.
