The first reason why your feet are getting thrown off is because either your not spinning the bar right or your only focusing on the bars. What I did first to learn it was do it one foot, I did that for a while then I did one foot with the other foot, simply then you practice with both feet on and you also need to think your feet are glued onto the deck then you should land it. ;) I hoped it helped

Don't lean back when u land . U can spin left or right it doesn't matter like the other guy said "practice with one foot " but if I could I would send u a vid but can't do 1.do not lean back 2.practice with one foot 3. Be careful learning trick 4. I learned by by keeping my feet on the ground and spinning the bar 5. After that try jumping and barspining 6.hope it helps u guys

Make sure you jump before throwing the barspin.

Just do it

Keep your deck on your foot

Keep your feet on

Try-hard

I just had to really think about keeping my feet on

Try passing it from one hand to the other instead of throwing it.
