They looked more or less normal except they looksed more like a step with the foot resting spot very wide. Wide in that you could put your whole foot on the bar and it acted like a wide step ...not the thinner bar that is normal for stirrups. Sort of looked like a cage not not quite.
I believe it was stated they are good for weak ankles and good for endurance. They may have been S America in origin but I believe there may be a place in the US where they can be ordered.
Does anyone know what I am referring to and their actual name or link to where they can be found ?
