This is an antique leather slipper or Devon stirrup. Such stirrups were used before the development of safety stirrups - the enclosed toe prevented the rider's foot getting trapped in the stirrup, so they would not be dragged in the event of a fall. The stirrup has a steel frame, this would originally have been covered in leather. The metal is now exposed and has a dark patina.
The slipper part is made of dark brown leather with a reinforced strip around the base of the toe .
There is a split in the back corner of the sole. Unusually this stirrup still has its original leather strap - it predates the special safety bars and straps seen today.
