Korsteel Knife Edge Stirrup Treads - Non-Slip Equestrian Stirrups for Horse Riding, Jumping & Dressage | Durable Stainless Steel Construction for Safety & Comfort

I measured the way the product said to and the size I bought was too big. They still work but don't sit flush inside my stirrup. If I had to do this again, I'd buy the 4.5 inch instead of the 5 inch.Regardless of the size, this product is a game changer for grip and support with the stirrups. I'm so happy these exist.
