The Tri-Zone Airlite Allsports Boots are the ideal 'All-rounder'. Very light and breathable, but also robust. Ideal for schooling, cross-country, hacking, or turnout. The Airlite triple layer system has been 'tested to the limits', meeting or exceeding the level of protection from penetration or concussion at levels of Advanced Cross Country. Inner layer - High impact resistant foam tested to dramatically reduce concussive force; Middle layer - breathable membrane that prevent debris from entering the boot, yet water and heat escape to keep leg cool and avoid adding weight after water jumps; Outer layer - EVA modeled into mesh which is rip resistant, flexible and very breathable.
