A NAME YOU CAN TRUST Brought to you by the manufacturers of the world's finest saddle pads. 5 Star Equine's Patriot sport boots are handcrafted in the USA. WHY WOULD THE MANUFACTURERS OF 100% PURE WOOL SADDLE PADS OFFER NEOPRENE SPORT BOOTS? Neoprene is not breathable and promotes heating, and it is not something that 5 Star recommends on your horse's back, chest or girth area. However, breathability in a horse boot is not something to be desired. By adding the element of breathability, you will sacrifice support, circulation and with the demands of the boot on the arena ground you may even be cultivating an environment for bacteria and other negative allergens to attach themselves to the skin of the horse.
