Similar to the VBX Max, the VBX Composite is re-engineered for demanding work sites — built to withstand plunging subzero temperatures, fortified with 360° bombproof waterproofing, and delivering all-day support and protection in demanding environments. With built-in composite toe protection, this boot is built for the worksite.
These work boots are compliant with PPE requirements, protecting against impact, compression, puncture, oil/chemical exposure, electrical shock, anti-slip, and cold-weather insulation.
An aggressive diamond-lug tread delivers superior grip on snow, ice, and mud, with reinforced high-wear zones for lasting durability in rugged terrain.
Fully seals the insulation from both sides, preventing water from flooding in or sweat from soaking through—eliminating the #1 cause of winter boot failure.
Layered insulation traps body heat while blocking the transfer of cold, creating a powerful thermal barrier for extended wear in extreme climates.
Built for the harshest winter environments, the VBX Bunny Boot delivers dependable warmth and comfort in severe subzero conditions, outperforming traditional cold-weather footwear.
The VBX (Vapor Barrier X) system is a waterproof layer that surrounds multi-layer wool insulation, keeping it dry. By blocking outside water and inside perspiration, it preserves warmth and performance in extreme cold, ensuring comfort even in overflow or extended use.
The Bunny Boot VBX Composite is certified to U.S. ASTM and Canadian CSA protective footwear standards. Testing includes:
They are built for industrial, construction, and commercial environments where safety and warmth are equally critical.
With proper care, composite toe boots typically last several years depending on use.
They’re constructed from a proprietary vulcanized rubber that resists cracking in extreme cold and provides a strong waterproof barrier.
All models are tested in real Arctic conditions as well as lab environments to run modern thermal testing with U.S. based footwear scientists for durability, insulation, fit, puncture, and slip resistance.
No, VBX Boots do not use Thinsulate. VBX boots keep you warm with a proven multilayer insulation system - built to perform where other materials can’t. Unlike synthetic fibers such as Thinsulate, which lose their effectiveness when exposed to the heat of vulcanization, our insulation stays durable, reliable, and ready for the cold.
The innovative Vapor Barrier X (VBX) technology prevents condensation from penetrating and freezing in the inner insulation layer, ensuring consistent warmth. The multilayer insulation system effectively blocks heat transfer, keeping the cold out while retaining warmth inside the boot. The boots feature vented hydrophobic insoles that keep feet dry and supported, as well as reinforcement of high-impact areas of the outsoles for enhanced comfort during prolonged wear.
For best results, clean your VBX Bunny Boots using a soft brush and warm water with mild soap. Avoid harsh chemicals or cleaners, as they can damage the rubber exterior. After use, remove the insoles and allow both the boots and insoles to dry completely before storing. Always store in a cool, dry place to maintain performance and extend the life of your boots.
We recommend synthetic or wool blend socks that wick moisture. Avoid cotton. For very cold conditions, a thin liner sock plus a thicker insulating sock works well. Always ensure there’s enough room to maintain circulation.
Yes. While VBX Bunny Boots come with a built-in liner system, they can accommodate aftermarket insoles or orthotics for added arch support or custom fit, just be sure not to compress insulation too much.
Yes, your feet may sweat, they’re designed as vapor barrier boots to trap warmth and block moisture from outside. It's important to:

VBX System
Our proprietary VBX (Vapor Barrier X) system encases the multi-layer wool insulation in a moisture-proof barrier, blocking both outside water and inside perspiration. This keeps insulation completely dry, ensuring lasting warmth and uncompromised performance in the harshest winter conditions.
Fully Waterproof
Fully constructed with vulcanized rubber, these boots are 100% waterproof and have greater abrasion resistance and elasticity in cold temperatures.
Multi-Layer Insulation
The multi-layer insulation system prevents heat transfer by shielding against frigid exterior temperatures while retaining heat inside the boot.
Ergonomic Performance
The boots feature vented hydrophobic ergonomic insoles designed to keep your feet dry and supported for superior comfort and performance.
True Fit Insoles
These insoles come in two sizes: standard and downsized. Advanced design allows for a comfort fit unmatched by similar cold weather footwear.
Elite Traction System
The outsole features deep-widespread diamond-shaped lugs for increased traction and stability on ice, snow, and mud while preventing mud and snow from accumulating underfoot.
Advanced Design Designed, tested, and proven in Alaska. After years of design, development, and field testing, we’ve reinvented the world’s most advanced Extreme Cold Weather Vapor Barrier Boot.
