Developed by a team that has over 20 years' experience in sport boot design, the Dynamic Edge boots by Cactus take sling strap technology, tendon and ligament support, and leg protection to a whole new level. Dynamic Edge boots are the only boot that offers two completely independent sling straps that pull from a fixed point on the front of the cannon bone. The Patent Pending "butterfly" straps offer equal amounts of support for both the inner and outer branch of the suspensory ligament. The fetlock joint needs support while also remaining flexible in order for equine athletes to perform at their highest levels. Dynamic Edge boots are designed to support flexion and mobility of the joints while not compromising tendon and ligament needs. Impact material technology is constantly changing and Dynamic Edge boots are leading the charge! Don't let the sleek design fool you. These boots are loaded with super dense, extremely lightweight, ultra-foam that provides unparalleled impact protection. Support, flexibility, and protection, without these factors, athleticism is compromised and the risk of injury is imminent.
