Why did the Prophet (peace and blessings be upon him) walk on the tips of his noble toes?

The questioner's intent is unclear. It has not been reported in the Prophet's guidance (peace be upon him) that he used to walk on his tiptoes. Rather, what is established is that when he walked, he would "taka'a" — meaning he would sway forward like a ship — and "taqalla'" — meaning he would lift his feet forcefully and clearly, as if descending from a high place.
