Exclusively Chick's! Durable, super soft, comfortable mesh boots that protect the legs from biting/flying insects and also provide protection from the sun's harmful rays. Velcro closures make them easy to put on and take off. They are flexible and won't impede your horse's movement. In fun, fashion colors! Set of Four boots. ADJUSTING FOR PROPER FIT: Start at the middle velcro strap and secure it, next secure the top velcro strap and lastly the bottom velcro strap. Return to the strap in the middle (fetlock/ankle area) and ensure it is snug enough so that the circumference of the strap is smaller than the horse's ankle but does not interfere with movement. If the velcro adjustments are too loose at the top and middle, the boots may slide down causing the horse to walk on them, which in turn may damage the boot.
