Make sure ur not pinching off blood flow, I sometimes do that if I lean on an ankle.
Regular activity helps with circulation. Do foot massages. Roll warm stones around them or use an object and feel it with your feet. Learn proper barefoot walking, posture, running. Walk around on different surfaces, not just a hard flat floor.
Do some light exercises in place like gentle jumps on the balls of ur feet.
