Built for the unforgiving depths of late-season hunts, the Crispi Wild Rock 400 EFX is the next generation of cold-weather performance. Whether you're glassing snowy ridgelines for elk or enduring long sits in a frozen tree stand, this boot delivers the warmth, traction, and durability to keep you hunting hard—no matter the forecast.
Crafted from water-repellent full-grain leather and reinforced with a full rubber rand, the Wild Rock 400 EFX was designed to thrive in brutal terrain and sub-zero conditions. A full-wrap GORE-TEX® Insulated Comfort Lining (~400g) keeps your feet warm and completely dry, even during prolonged exposure to snow, sleet, or standing water.
The aggressive CRISPI® x Vibram® Full Control Outsole is built to grip through mud, ice, and uneven ground, while the EFX Elastoflex midsole cushions each step, reducing fatigue across long miles. With a 3 Flex Rating, the Wild Rock 400 strikes a perfect balance between support and flexibility, providing stability without sacrificing agility.
Weighing in at just over 2 lbs per boot, this 10-inch powerhouse delivers premium ankle support without bulk. Whether you're still-hunting predators or navigating backcountry trails, the Wild Rock 400 EFX ensures all-day comfort, warmth, and resilience.
