The new Smelter Collection represents the pinnacle of safety, performance and innovation for workers in high-temperature, high-risk environments where safety isn’t just a requirement, it’s a necessity. Designed as a complete safety system to endure the extreme, every component works together to shield against the hazards of extreme heat, molten metal and crushing forces, with exceptional comfort provided by the ORTHOLITE® foam insole.
NEXT GENERATION OUTSOLE
XPAN 2.0 sole TeCHNOLOGY
The XPAN 2.0™ outsole is built for molten metal exposure and extreme heat environments. Tested to resist temperatures up to 1000°C (1832°F), it delivers exceptional abrasion resistance, slip resistance, and shock absorption. Lighter and more flexible than previous generations, XPAN 2.0™ offers advanced protection and durability to meet the toughest demands of foundries and metal industries.

XPAN 2.0 TECHNOLOGY
THE NEW XPAN 2.0 SOLE
HEAT-RESISTANCE
XPAN® 2.0 features a vulcanized rubber compound engineered for smelting and metallurgical environments. It offers reliable heat resistance by maintaining its integrity and structure when exposed to hot surfaces or molten splash.
Slip-resistance
The XPAN® 2.0 outsole is designed for high-risk industrial surfaces, with a certified slip-resistant lug pattern that maximizes contact and channels away fluids to maintain secure footing in both wet and dry conditions.
To evaluate slip resistance, we use the SATRA TM144 method on dry and wet quarry tile as well as stainless steel. This test measures the dynamic coefficient of friction at both the flat and heel areas of the boot. The results below show how the outsole performs under each condition.
| QUARRY TILES - DRY | Flat 1.27 | Heel 1.18 |
| QUARRY TILES - WET | Flat 0.6 | Heel 0.58 |
| STAINLESS STEEL - WET | Flat 1.27 | Heel 1.18 |
To evaluate slip resistance for the U.S. market, we use the ASTM F2913-23 test method. This standard measures the dynamic coefficient of friction on surfaces such as dry and wet quarry tile and stainless steel. Results are collected at both the heel and forefoot to reflect realistic walking conditions.
| QUARRY TILES - DRY | Forepart 1.28 | Heel 1.32 |
| QUARRY TILES - WET | Forepart 0.52 | Heel 0.51 |
| STAINLESS STEEL - WET | Forepart 1.28 | Heel 1.32 |
To meet international slip resistance requirements, we use the ISO 20344 test method (Section 5.11). This procedure measures the dynamic coefficient of friction on ceramic tile surfaces contaminated with water and detergent, simulating realistic slipping hazards. Measurements are taken at both the heel and forefoot to reflect true walking conditions.

Proven Molten Metal Performance
Complete Molten Metal Protection
Molten Metal Design
- XPAN® 2.0 vulcanized rubber outsole resists deformation and breakdown when exposed to hot surfaces and molten splash.
- REALFLEX™ external met guard deflects slag and protects high-risk areas like the laces and upper foot from impact and thermal hazards.
- Seamless vamp construction, extended tongue, and heat-resistant components work together to reduce entry points and maintain protection under molten metal exposure.
Spoon Test
The spoon test simulates sudden contact with molten metal poured directly onto the boot's surface. This test evaluates ignition resistance, splash deflection, and upper material performance under intense localized heat.
Dip Test
The dip test evaluates prolonged exposure by submerging the lower part of the boot into molten aluminum. It measures how well the outsole and construction resist continuous heat, deformation, and material breakdown.
CERTIFIED PROTECTION
Complete Metatarsal Protection System
REALFLEX™ External Metguard
The REALFLEX™ metguard is a high-performance external shield that protects the metatarsal zone against falling tools, heavy machinery, and molten splash. Its ergonomic flex design moves naturally with the foot while maintaining full protective integrity. This ensures reliable protection without sacrificing mobility or comfort, supporting critical maneuverability in confined or high-heat environments.
NANOTOE® Composite Toe Cap
This advanced nanotube composite toe cap delivers certified impact and compression protection with a thinner, lighter build than traditional caps. Designed to protect the front upper portion of the foot, it works in tandem with the REALFLEX™ metguard to form a complete safety system. Its slim profile ensures space efficiency and lasting comfort without compromise.
SHIELDED COMFORT
All-Day Comfort Without Compromise
Polyurethane Midsole
Delivers superior shock absorption and long-lasting cushioning that reduces pressure on joints and supports your stride through every shift. Its responsive, anti-fatigue properties are ideal for hard surfaces and demanding industrial conditions.
OrthoLite® Insole Comfort
Breathable comfort, the OrthoLite® insole keeps your feet cooler, drier, and reduces foot fatigue. Its low-compression design resists flattening over time, offering consistent comfort throughout the day.
Wide Adjustable Fit
Featuring the SPACE-R™ insert and a generous toe cap design, this system lets workers fine-tune their fit for all-day comfort. It reduces pressure points and adapts to changes in foot shape over long hours, without sacrificing safety.
