These are Acavallo stirrups. They are designed to prevent the stirrups from slipping, allowing for a secure footing. The footrests have a firm, textured surface to prevent slipping and are designed to allow dirt and mud to fall through. They also provide good support for the sole of the foot. The stirrups are designed to face forward when hanging, so you can easily step back into them if your foot comes out. They also prevent the footrests from scratching the saddle during storage. They have been used, so there are some scratches and discoloration (the discoloration can probably be removed with a cleaning solution), but it shouldn't be noticeable when riding. I have taken care of them, so they are in good condition.
