Hi. What worked for me for the challening footlock are these 3 steps, in order:
1) Pull the tail first for slack, and don’t let go of that. Keep your right hand there.
2) Then rotate the foot 360 degrees to be able to scoop/loop the tail on foot.
3) Then bend down closer to the right foot to create the lock with that right hand.
I hope these help. My tail is long and thus heavy, that’s why I had to pull first for slack.
Cheers!!
