The Wild Rock 400 EFX is the evolution of a classic, designed for those who thrive in the great outdoors, no matter how extreme the conditions. Building on the trusted legacy of the original Wild Rock, this updated model continues to excel in providing warmth, durability, and protection.
Originally crafted for late-season hunts, the CRISPI® Wild Rock boots were renowned for their ability to withstand the cold temperatures and harsh conditions of winter. The Wild Rock 400 EFX inherits this resilience, featuring ~400g of GORE insulation that wraps entirely around the boot. This ensures your feet remain warm and dry, even during extended exposure to extreme wet or snowy environments. Whether it's a late-season whitetail hunt or an arduous trek through snow-covered trails, these boots scream, “take me outside,” even on the coldest and wettest days.
Constructed with the finest full grain leather, the Wild Rock 400 EFX is both tough and comfortable. The CRISPI® x Vibram® Full Control Outsole is a standout feature, designed with deep lugs that provide exceptional grip in any condition, be it dirt, mud, or snow. This advanced outsole ensures superior traction on slippery surfaces, giving you the stability and confidence needed to navigate challenging terrains. The CRISPI® EFX Midsole offers superb cushioning and support, minimizing fatigue during long days in the field. The boots feature a full rubber rand, enhancing durability and protection against abrasions. With a 3 of 5 flex rating, they provide the perfect balance of flexibility and support, ideal for various terrains and activities.
Available in sizes 8-13 (including half sizes) and 14, with wide options for a tailored fit, these boots cater to a wide range of foot shapes. The 10-inch height offers excellent ankle support and coverage, while their lightweight design, at just 2 lbs per boot, ensures you can move with ease.
Optimal for late-season whitetail hunts, cougar hunts, mule deer hunts, elk hunts, predator hunts, tree-stand hunts, or moose hunts, the Wild Rock 400 EFX is your ultimate partner for outdoor adventures. It replaces the beloved Wild Rock, offering upgraded features that make it even better suited for tackling extreme conditions. With the Wild Rock 400 EFX, you can confidently step into the wild, knowing your feet are well-protected and ready for the journey ahead.

Sizing Guide
- Fit: CRISPI® boots generally fit true to your everyday athletic-shoe size. If you are between sizes, wear heavy merino hunting socks, or plan to add an aftermarket insole, consider going up a half size.
- Width: Offered in standard and wide (EE) widths — wide sizes are the ones marked “EE” in the size menu (US 8–13).
- Sizes available: US 8–14 (half sizes through 13).
- Measuring: Try boots on (or measure your feet) late in the day with the socks you will hunt in. You want a thumb's width of room in front of your longest toe and a heel that stays planted when laced snug — heel-lock lacing helps if the heel lifts.
- Break-in: Leather boots settle in with wear; plan a few shorter outings before a long hunt.

If we got it wrong, we make it right. If your order turns up damaged, faulty, or it simply is not what you ordered, we cover the return shipping and refund you in full. Send us a photo and we will sort it out — you should not be out a cent for our mistake.
Changed your mind? That is fine too. Send it back and we refund the full price of the product. Return shipping is on you in that case, and the gear has to come back to us complete and in sellable condition — unused, undamaged, with the packaging, parts and paperwork it arrived with. Once it lands and checks out, the full product price goes back on your card. Shipping is the only thing you are out.
Built-to-order gear is final sale. Custom arrows and anything else built to your spec cannot be resold, so we cannot take those back.
Get in touch before you ship anything so we can point you at the right store and keep an eye out for it.
