The first part of having good footwork is making sure you've got the correct fitting shoes. This video highlights what happens with baggy shoes and the difference correct fitting shoes makes.

Also, make sure there isn't excess material, or a baggy nature once the foot is in. "Fits like a glove" should spring to mind.
