Cold water therapy in a boot. Micro-crystals turn to a cooling gel when soaked in water. The crystals swell into the quilted fabric spaces to form a soft gel pad that hugs all parts of the leg when the boot is fitted. The cold compress reduces inflammation, swelling and bruising, cools tendons after exercise and treats soft tissue injuries. Mess free and reusable ? the gel is contained within the fabric quilting and returns to micro-crystals when dry. Horse remains mobile while receiving treatment. Touch close fastenings. Set of 2.
