The NanoFlex horseshoe was designed with the comfort and LAMENESS PREVENTION of the horse in mind. Since the Romans, horses have been shod using metal shoes. These shoes, while sufficient for the times, now are antique and borderline barbaric. The steel or aluminum horseshoes used today DO NOT FLEX! NanoFlex horseshoes are designed to move and expand in every direction as the hoof does. Nature did this to relieve some of the shock from the thousand ‘s of pounds of pressure as each step is taken by the horse. This revolutionary new look at the construction and design of horseshoes has led some very impressive empirical evidence suggesting the future of horseshoes is to have flexibility. A university study proved OVER 80% more blood circulates from the knee through the hoof by using an inferred camera while a horse was trotting on a tread mill. The horse had one hoof shod with metal shoes while the other three hooves were barefoot! USING NanoFlex SHOES ARE BETTER THAN GOING BAREFOOT.
