high heeled shoes/ high heel shoes

Hello!
I would like to know which is the correct alternative? high heeled shoes or high heel shoes ?
Do they have different meanings?
Thank you for your time!

I would say “high heeled shoes” is the most correct, but according to this Google ngrams graph, “high heel shoes” is catching up quickly: books.google.com/ngrams/graph?co … moothing=3 They both have identical meanings.

Thank you for explanations!
