Welcome to the Mercs. This is a quote from the CRL that may help answer your question, I have highlighted the the specific area that concerns you. I believe that boots with a wedge fall under that description, but an App team member can clarify.
"Boots:
Combat/Utility boots are considered the primary accepted boot for armor.
Labels and brand names should be removed or covered.
Shoe-laces MUST be covered with armor or some sort of boot/ankle spat.
High heels/stiletto female boots are not acceptable mandalorian armor attire. Platform boots are acceptable."
