The Tri-Zone® brand is built on a core principle of zoned protection – unrivaled protection where it’s needed most. Tri-zone boots provide proven protection with the additional benefits of being lightweight, cool and flexible. Equilibrium Impact XC boots are made with Rotex, a tough, stud resistant exterior. Use of Rotex has increased the outer strength of the boot, without losing any of the key features Equilibrium Tri-Zone boots are known for. Proven protection from penetration and concussion, the boots are supple, cool, light, and won?t absorb water. Trusted by professionals worldwide. ? The Tri-zone Impact XC Boots use the latest material technology to create a highly protective boot which is very light, flexible, and breathable. Safety tested in independent laboratories, the Impact XC boots have been proven for both concussion and penetration protection at the levels of force experienced by a horse hitting a XC fence at speed or striking himself. ? Adding weight to a horse’s leg can significantly reduce performance. Even with the high level of protection afforded in the XC boots, these boots are so light, they float on water. Additionally, the boots are highly flexible so they bend and flex with the horse’s leg for full range of motion.
