Veredus Carbon Gel Vento Grand Slam Ankle Boot Celebrating the Grand Slam of show jumping! One victory is not enough - to achieve the Grand Slam, the rider has to win three events - CHIO Aachen, CSIO Spruce Meadows, and CHI Geneva. In 2015, Scott Brash became the first Grand Slam winner in history. Such an unprecedented achievement deserves to be recognized. Veredus(R) is proud to introduce the Grand Slam Carbon Gel Vento Gold Edition - all the protection and ventilation riders have come to love, in a genuinely celebratory style! The first ankle boot that guarantees double ventilation! More dangerous than any impact is the effect of heat buildup on your horse's legs. The Veredus(R) VENTO releases heat through their exclusive double ventilation system. Cool air is drawn in through the bottom vents and heat is released through the top vents. Air circulation within the boot is aided with Aerox micro perforated neoprene and 3D Mesh Ducted fabric. Features the same supreme protection of the original Carbon Gel boot: best fitting and performing boot for jumpers, anatomic design, main shell composed of semi-rigid polyurethane. Gel lining in the strike area for the ultimate in shock protection, elastic straps and fast release ferrules with narrowing hook holes to allow fast and easy hooking and release, without compromising security. Sold in pairs. Made in Italy.
