LeMieux Exo-Flex boots are an expertly designed fusion of technical excellence and functionality designed around three central pillars for a performance horse boot. Protection Support Shock absorption The Exo-Flex tough outer skeletal shell provides essential protection with its carbon strike guards at the rear of the tendon and side of the joint. Integrated into the body of the boot is a layer of ACF artificial cartilage biometric foam which absorbs and dissipates up to 90% of impact from the force of your horse landing after a jump, or from a direct strike on the boot. Internal perforated dynamic neoprene contours support the tendon and fetlock with breathable bamboo and cooling nylon inner lining and outer 3D mesh. Forward-facing vents force incoming air to circulate and cool the tendons whilst top vents release rising heat. Minimal in profile, structure and weight, these are ideal jumping boots, avoiding unnecessary bulk at the point of passing over a pole. 25mm and 30mm rotating strap widths are inter-changeable with three length options for a precise fit.
