Leather that is coated with an external layer of color then brushed off with a burnishing wheel for a richer, worn finish.

Buffalo leather:
Leather made from the hide of buffalo—known for its distinct rustic look and feel as compared to cowhide leather.

C

Cambrelle:
Patented, non-woven synthetic fabric used primarily as lining for shoes and boots. Designed to increase breathability, moisture-resistance and avoid abrasion.

C-Cap:

Provides lightweight cushioning and flexibility.

 

Cement Construction: In this rugged construction, the upper is shaped around the bottom of the last, rather than flared out, and then is cemented to the combined midsole/outsole unit. This process helps cut weight and provides a narrower profile for the boot.

Collar:
A layer of material, often leather, found at the top of the boot. Usually padded or cushioned for extra support for the ankle or lower leg.

Composite toe:
A hard synthetic plate found in the toe box of the boot or shoe to protect from crush or impact injury.

D

Deer tanned:
Leather manufactured and processed with deer hide.

DBL:

DBL outsoles are up to 50% lighter than traditional materials. DBL is a natural brilliant white without using the whitening chemicals that weaken the outsole and make it more brittle. The purity results in: no fading or streaking for the life of the shoe, resistance to stains and chipping, and an increased softness and flexibility.

Doubled stitched:
A sewing technique that uses two seams instead of one when sewing together leather boots and shoes for a more reinforced and secure stitch.

Durashocks:

A Wolverine brand name for their lightweight dual-density construction that weighs one third as much as rubber yet absorbs four times the force. Both Wolverine Boots and Bates Boots utilize this technology.

 

Dri-Lex:

Has excellent abrasion resistance and is the only knit lining in the world approved by the American Podiatric Medical Association. It was made to be a step above Cambrelle in quality and uses a special hydrophilic nylon moisture control fiber to wick away moisture. This lining is found in many of our top brand items, including Wolverine Boots.

Dynamic Suspension System:

A fiberglass shank is best for someone who wears their work boots for hours of the day. It gives the arch amazing support and the feet will feel less tired.

 

Footbed:
The inner part of the shoe that runs under the bottom of the foot. Also referred to as the insole.

Full-grain leather:
Leather that has not been sanded, buffed or extensively altered leading to its use. Includes increased durability and breathability due to its minimal treatment and preparation of the hide. Considered one of the highest quality forms of leather.

G

Goodyear welt construction:
A traditional manufacturing method that fastens a leather, linen or synthetic strip to the upper and sole for a secure build. Allows the shoe or boot to be re-soled repeatedly for a longer lifespan.

GORE-TEX:
State-of-the-art Gore-Tex® fabric linings offer the highest performance in durable, waterproof, breathable footwear technology. GORE-TEX® has over 9 billion holes per square inch that prevents water from getting to your feet while allowing sweat vapor to pass right through keeping your feet dry and comfortable in all conditions.

H

Heel:
The part of the boot attached to the back of the sole. Comes in a variety of shapes, sizes and materials and often includes added support or shock-absorbing features.

Heel-To-Toe Rocker Sole:

This sole will make the workday go by much more smoothly. It reduces the stress that is put on the forefront of the foot and by doing so making the footwear more comfortable

I

Insole:
The layer of material between the foot and outsole or bottom of the shoe. Forms the inner base of the shoe. Also referred to as the footbed.

L

Logger:
A style of boot that resembles those worn by lumber workers.

M

Maxum Lite Outsole:

Shock absorbing relief on the most unforgiving concrete and tile surfaces. The blown urethane process traps muscle-saving, fatigue-beating air within every sole. Maxum urethane grabs tight and holds on in wet or slippery environments. Internal components give this sole an ESD rating that meets ANSI Z41 requirements

 

Metatarsal guard:
Protective material that is strapped, either externally or internally, to footwear to prevent crush injury or severe impacts. Often made from steel, plastic or aluminum. Also can protect against sharp objects puncturing the bottom of the boot, although not specifically designed for puncture protection.

Puncture resistant:
Material that covers the exterior of the boot or shoe designed to protect from forceful and/or sharp impacts against the shoe. Often built from tightly woven fabric or small, ceramic plates in the fabric coating.

S

Safety toe:
A steel or composite guard located in the toe of the boot or shoe to protect from crush and impact injury.

Sized Sock:

A sock knit to a number of specific sizes (not size ranges) that correlates (although not directly) with a person’s shoe size. They will be sized by number, ranging from size 8 to 15.

Shank:
A metal or composite plate located in the sole of the boot. Designed to help workers stand on their feet longer, especially on narrow pegs or bars. Also protects against sharp objects puncturing the bottom of the boot.

Shock Mitigation System:
A 5.11 Tactical brand-exclusive technology that utilizes several materials and footwear technology to create all-around support for high-impact activity.

Slip resistant:
Footwear with an outsole or bottom that provides traction or grip on slick surfaces caused by oil, water or other chemical substances.

Static dissipative:
Technology found in certain boots and shoes that reduce the risk of static shock or build up in the individual wearer and the footwear itself. Optimal for electrical hazard work environments. Also referred to as “electrostatic dissipative.”

Stitchdown Construction:

Stitchdown construction provides a wider platform for increased stability. Boots constructed under this method can be re-soled, adding years of life. First, the upper is shaped to conform to the last, then flared out and cemented to the midsole. Then the upper and midsole are stitched together with heavy, interlocking thread to create an even more secure attachment. Finally, the outsole is cemented to the midsole upper unit.
