New, updated version of the popular Olympus tendon boots from Veredus - now with Vento technology. The boots have a double ventilation system that releases excess heat through the two inner layers as well as through the ventilation holes at the bottom and top of the boots. An inner layer of 3D mesh distributes heat evenly all over the boots, and the layer closest to the horse's leg is microperforated neoprene. The boots are anatomically shaped to fit the horse's legs and allow good freedom of movement. The main shell is made of two separate polyurethane parts with different thicknesses and flexibility. The inner shell is more rigid to protect against impact and knocks, and the outer shell is more flexible to promote the horse's natural movements. Shock-absorbing EVA foam provides added protection for tendons. Two elastic straps with quick release fasteners make the boots easy to put on and take off and prevent excess strain from over-tightening of the straps. Note: The boots in size S look slightly different, because they are too short for the triangular Veredus logo to fit at the top.
