I have a few questions about shoes...

The other day, it was brought to my attention that skirts should be worn with a shoe with low vamp. Some shoes are obvious, but others are complicated. I am wondering if shoes that have higher straps, T straps, cross straps, or even ankle straps would have the same effect as a low vamp shoe that is completely open? Here's a few examples of what I'm talking about:
