These Shires ARMA Cool Hydro Therapy Boots are designed to provide cold water therapy to your horse’s legs. They feature a quilted fabric with micro-crystals that swell up when soaked in water to form a soft gel pad that hugs the horse’s leg. Great for reducing inflammation, swelling, and bruising, cooling tendons after exercise, and treating soft tissue injuries, these boots are mess-free and reusable – the gel returns to micro-crystals when dry. Plus, with touch close fastenings, your horse can remain mobile while receiving treatment. This set includes two boots.
