A little later than expected, but the new Equine Fusion Performance boot is now in stock! And it looks as though it was worth the wait. The boot seems a much tougher version of the Equine Fusion Ultra, with reinforced material in the heel area, and better fastenings overall. The pastern strap is the same as on the Ultra, although the strap is stiffer, but the front strap system has been redesigned and seems much quicker and easier. The tread is deeper, and I can't wait to try them out!
