Splint boots are protective gear designed for horses, primarily used to shield their legs during activities like riding or training. They are made from durable materials and feature padding to absorb impact, helping to prevent injuries to the horse's legs, particularly the splint bones. These boots are typically secured with adjustable straps, ensuring a snug fit without restricting movement. Splint boots come in various sizes and styles to accommodate different horse breeds and activities, making them a popular choice among equestrians for maintaining horse health and safety.
