Sprenger's new BootProtect tracks protect the riding boot with a rubber coating on the inside of the tracks, invisible on the outside. The rubber also ensures that the spurs do not slip on the foot and stand out due to their slender appearance. Because the outside of the spurs is made of stainless steel, they are ideal for sensitive horses or during shedding season. Like all tracks in the Ultra Fit series, the BootProtect tracks are 100% shatterproof
