It is never a good idea to use Word formatting in InDesign. Both are completely different programms with a different focus. YOu should set up your formatting styles completely in InDesign and forget every formatting from Word.
Best practice is to use styles in Word, their formatting doesN#t matter, only their names are important. Don't use section brakes, footers, headers, text frames. Set up the styles in InDesign and you can import Word text files with limitted problems only.
