Rear high training boot designed for show jumping and flat work at home. It wraps around the entire hock, providing exceptional protection to the fetlock and upper part of the hock. The heat released from the horse's leg passes through the micro-perforated neoprene layer and is distributed in the 3D mesh ducted fabric. Fresh air enters through the air inlets and directs the heat upwards to the outlet grid, ensuring both horizontal and vertical ventilation. Features 3D mesh ducted fabric, Air Grid, enveloping AEROX micro-perforated neoprene, and a double velcro closure.
