I hope it?s ok to post another thread with a different problem ?

Anyhoo, my HT JL Superman?s left foot keeps popping out whenever I contract the foot 🦶 or when I basically pose it for flight pose and I want to position the foot with toe pointing downwards (I hope that makes sense ?)

I can pop it back in, but it limits the range of movement as the other foot can handle better positions.

What would you recommend ?
