The Jacks Show Boil Boot is designed to help prevent and protect against shoe boils, also known as capped elbow. Made from durable, smooth black rubber, the donut-shaped design creates a cushioned barrier that prevents the horse’s hoof or shoe from contacting the elbow when lying down. This protective boot straps securely around the pastern using an adjustable nylon strap and buckle, keeping the padded ring positioned to shield the elbow from irritation or injury. The simple, durable construction makes it ideal for horses prone to capped elbow or those resting on firm surfaces. Key Features: Donut-shaped rubber design helps prevent shoe boils (capped elbow) Adjustable nylon strap with buckle for secure pastern placement Durable smooth rubber construction for long-lasting protection
