I’ve personally seen and heard a million horrible stories about free jumps. I really think they are bad unsafe stirrups.
I was out of the loop a bit when I saw them for the first time but my mind immediately flashed to all the ways they could get caught in things. The first time I rode in them they got caught in my breastplate. My fault? I mean yes probably but I don’t ride so bad and still…
Another time a friend of mine was walking horse to the mounting block, stirrups rolled up, horse bit at a fly and got their bottom teeth stuck to them and collapsed to the ground before we could get them off. This happened twice actually.
Another time, person was having a hard time getting canter, gave a kick, outside of stirrup caught in fence and got stuck to it. Gave a loud crack when it broke off.
Countless stories of reins getting caught in them.
This story I only know through gossip but kid had a horse fall on her and still stirrup stuck to her foot, got dragged and broke like every bone in her arm.
They are really popular but I think they’re death traps. I’ve pretty much never had an issue with stirrups except free jumps.
