foot falling asleep

What causes that strange feeling when your foot falls asleep?

Here’s a link to MSNBC where it’s explained.

“Pins and needles” or “paresthesia” is also called “formication,” the feeling that your skin is crawling with ants.

'Trivial Pursuit–let me tell you, there’s the story of my life. Anway, forget that “feedback device for self-protection” stuff. The
numbness you’re talking about is called neurapraxia, and it usually occurs when some major nerve gets compressed between a
bone and some other hard object, such as a table or another bone. Nerves that are particularly vulnerable to this include the
ulnar nerve, which runs through the funny-bone channel in your elbow, and the peroneal nerve, which runs through a similar
channel at the top of the fibula near the knee. ’
