The 100% made in Italy ”KING CARBON AIR” have been studied to contain and give support to the tendon apparatus while defending horses during dressage from collisions and bruises at fetlocks and cannons. They are equipped with revolutionary locking system (PATENTED) that facilitates the positioning on the leg, provides more support than conventional boots on the market, as well as provides perfect adaptability and stability. They are composed by external TPU structure with differentiated thickness, transpiring thanks to the perforated Neoprene and ventilated by 6 Air-Vents located over the fetlock. Gel-Tech is included between the external TPU structure and the Neoprene support, where necessary, working as shock absorber and comfortable padding. Carbon Fibre elements are present under the shell to thermally insulate the joints from the heat generated by external friction, while increasing the mechanical resistance to impacts. Closed to the long-pastern, have been created a Flex-Zone, necessary to allow maximum freedom of movement to the limb. The elastic straps with quick-release-tip have been calibrated for a secure closing, they are in-fact provided of double locking system (horizontal\vertical). Its dimension and absolute ergonomic shape have been developed copying accurately the limb structure, guaranteeing a perfect positioning while avoiding any kind of stress.
