I move my legs around on long trips, no pain. I put my heels on the pegs like a foot rest. I put the the sole of my shoe on them but the heel part too to stretch my ankles and then back to the normal position. Moving between these keeps me from getting cramped from just 1 position.

I learned all I need to know about life by killing smart people and eating their brains.
Eat right ,Exercise ,Stay fit, Die Anyway!
