I got sent these to try from a company, much appreciated, I like to have the opportunity to test items. They are the double bent leg with the top rotated 90 degrees.
I liked the stirrups, they do hang very still and are easy to pick up when I lost one intentionally. They are a nice weight, some on the market I have found very weighty.
I wasn’t able to continue the trial as I have issues with one of my feet. It kept losing the stirrup and slipping round. No reflection on the item.
From what I did see and use I liked them. Just be aware when you run up the stirrups the slots do press into your saddle. There are little stirrup covers on the market now, maybe for this type.
Please note these are left and right specific as are the single bent legs.
