Trying to find rare design stirrups

Hello,

I need some detective work. I am trying to find a certain stirrup. I can't remember the name but can describe them. They are made in the idea of a ski. They take the full foot of the rider and are built for English style saddles. They have a special strap that comes off the back in case a fall. I can't remember the name of them. Does anyone know the stirrup I'm taking about and the name of them?

Please help.

Thanks

I didn't find the right solution from the Internet.
