Steel Toe
Steel protective toe cap meets the CSA Z195-14 Grade 1 and ASTM 2413 I/75 and C/75 impact and compression standards.
ALUMINUM TOE
Aluminum protective toe cap meets the CSA Z195-14 Grade 1 and ASTM 2413 I/75 and C/75 impact and compression standards.
Composite Safety Toe
Non-metallic toe cap meets CSA Z195-14 Grade 1 and ASTM F2413, I/75, and C/75 impact and compression safety standards.
Nano Toe
The latest generation of composite safety technology, carbon nanotubes are combined with fibreglass resin to create one of the strongest and lightest safety toes on the market. Our nano toes are dual ASTM F2413 and CSA Z195 certified.
External Metguard
External met guards are affixed on the outside of the footwear, and offer additional metatarsal protection against impacts beyond the toe cap.
Internal Metguard
An internal met guard offers enhanced protection for the small metatarsal bones of the feet. Affixed between the inner lining and the outer leather, this component extends from the top edge of the toecap up towards the tongue of the boot for a seamless protective barrier.
Lightweight performance
At Terra, styles included in our Lightweight assortment are designed to provide maximum comfort and agility while minimizing the overall weight of the footwear. Engineered materials and components that prioritize breathability, flexibility, and durability are strategically used in all parts of the shoe or boot. These models are crafted to offer a feather-light feel without sacrificing protection, performance, or quality.
Metal Free
All safety components, hardware and materials are non-metallic, and meet or exceed the applicable safety standards and performance specifications required.
Puncture Resistant
Meets ASTM F2413 and CSA Z195-14 puncture resistant standards with protective soles.
Electric Shock Resistance
Meets CSA Z195-14 electric shock resistance. Sole provides resistance to electric shock, intended to withstand 18,000 V and leakage current not exceeding 1 mA.
Waterproof Membrane
Full-booty construction and welded insulation offer complete around-the-foot waterproofing protection.
Static Dissipative
Meets CSA standards for SD. Each test specimen shall fall within a range of 10^6 to 10^8 Ohms.
Super-Static Dissipative
Meets CSA standards for SD+. Each test specimen shall fall within a range of 10^6 to 3.5 x 10^7 Ohms.
CSA Icons
CSA Green Triangle
The CSA Green triangle indicates sole puncture protection with a Grade 1 Protective toe to withstand impacts up to 125 joules. Sole puncture protection is designed to withstand a force of not less than 1200 Newtons (122 kilos / 270 pounds).
CSA White Rectangle
The CSA White rectangle with orange Greek letter omega indicates soles that provide resistance to electric shock. Such certified footwear contains a sole and heel design assembly that, at the point of manufacturing, has electrical insulating properties to withstand 18,000 Volts and a leakage current not exceeding 1mA for 60 seconds.
CSA Yellow Rectangle
The CSA Yellow rectangle with a black "SD" indicates soles are static-dissipative. The outer soles are made from an anti-static compound, capable of dissipating an electrostatic charge in a controlled manner. The test criteria are 10^6 to 10^8 Ohms. Note that SD footwear without toe protection will not have sole protection certified by CSA.
CSA SD+
The CSA Yellow rectangle with a black "SD+" indicates soles are super static-dissipative. This protection feature is similar to SD, except the test criteria are 10^6 to 3.5 x 10^7 Ohms.
Metguard Impact Test
A new standard from CSA – only metguards bearing the "M" emblem are CSA approved. The mass (22.7kg) is dropped on the centred boot, impacting the metguard.
Technologies
KRYPTOE®
20% lighter than previous generations, KRYPTOE® technology incorporates specially woven fibres with highly impact-resistant resins. The result is a globally certified, lightweight, low-profile composite toe.
Vibram® FIRE & ICE™
FIRE & ICE™ outsole provides superior traction and performance in high heat & sub-zero temperatures.
XRD® Metguard
New breakthrough flexible materials with XRD® technology. Designed to stay flexible in motion but turn into an ultra-dense protective barrier upon impact.
TecTuff™
TECTUFF™ PU coated leathers use a proprietary process and chemistry which delivers extreme durability. The polyurethane formula is securely bonded through heat and pressure to the leather substrate. The resulting finish is the most durable in the industry and is impervious to dirt, oil, and stain penetration.
TERRASPHERE®
Our exclusive TERRASPHERE® and TERRASPHERE+™️ liners are engineered for maximum thermal retention and performance. Strategically selected materials – including Mylar film, and PrimaLoft™️ and Thermolite™️ insulations – are combined to shield the foot from the cold. Heat is trapped and reflected back to the foot using special assembly techniques and precise thicknesses, delivering unparalleled warmth. TERRASPHERE® and TERRASPHERE+™️ are groundbreaking insulation systems that achieve comfort ratings from -40°C/-40°F to -60°C/-76°F.
FIRMA-FLEX®
TERRA FIRMA-FLEX® lightweight Metal-Free technology. This revolutionary combination of super-weaved high tensile fabric and resilient polymer compounds makes for one tough toe- cap. The sole plate, constructed of laminated layers of this extraordinary composite, is even stronger: averaging 20% more resistance than traditional steel plates.
JetBound™
The Terra® JETBOUND™ insole delivers instant comfort. Ultra-soft, high-rebound EVA pressure pods absorb strike forces while the anatomically contoured shape provides underfoot support. A strong, stable EVA chassis helps lock the foot in place to deliver unmatched comfort, support and dynamic elasticity at work.
JetStride™
Delivers advanced rebound technology in a lightweight, durable design. Pressure pods, engineered for extra bounce, are moulded in high-impact strike zones for on-target cushioning.
CLEANFEET®
CLEANFEET® odour control treatment is a game-changer in the footwear universe. This patented technology doesn’t just help odour - it actually works to prevent odour before it starts, CLEANFEET® stops odour dead in its tracks.
