One of the great advantages of multiple modality instruction is that it provides a means of (at least momentarily) capturing the full attention of the mind to the task at hand. Haptic techniques, engaging the body as they do, if done with correct form and perhaps some eye tracking, are "mindful" or mind-filling in the best (felt) sense. It is not that clear explanations, discussion, insight, planning and disembodied drilling related to a learner's pronunciation are not helpful; they are, of course--but they can also easily interfere with efficient anchoring of sound change.
In other words, stop thinking about pronunciation and how difficult, time-consuming and anxiety-producing it can be. Just do it (haptically)!
