Many people say this is because you've cut off the blood supply to your foot, but your nerves are to blame. Nerves are like tiny threads or wires that run through your whole body, and they carry messages back and forth between your brain and body.
When you sit on your foot, you temporarily compress, or squash, the nerves in that area. These nerves can't send messages back to the brain normally, and so for the moment, the connection is cut off and you don't feel anything. It's kind of like a phone call where your friend hangs up and you haven't yet: Your brain is saying "hello," but your foot isn't able to answer.
After you stand up or uncross your legs and the nerves are no longer compressed, the feeling in your foot soon comes back. It might feel a bit tingly as this happens, like pins and needles or even a bit painful. But it only lasts a few seconds as the connection returns to normal, and it won't hurt your body

Pins and needles
'Pins and needles' (paraesthesia) is a sensation of uncomfortable tingling or prickling, usually felt in the hands or feet. The affected area is sometimes said to have 'fallen asleep'. A common cause is leaning or lying awkwardly on a limb, which either presses against the nerves or reduces the blood supply to the local area. Changing position quickly restores normal feeling. Any numbness is soon replaced by the tingling and prickling sensation, as the nerves start sending messages again to the brain and spinal cord. In some cases, pins and needles are caused by nerve damage or certain disorders of the central nervous system. Always see your doctor if you experience frequent or persistent bouts of pins and needles.

Lack of Circulation. Occassionally if it remains cut off it will in turn "Fall Asleep". But by the time you're feeling the pins and needles the blood is already getting back to the foot. Thus the difference between pins and needles and a sleeping body part is time duration and measure of the lacking circulation.

Depending on what position you sit in, blood circulation gets cut off to your legs.

Check with your MD. It could also be a pinched nerve in your lower back.
