insulated
insulated

Shoe construction that helps retain body heat and protect against cold environments. Insulated footwear helps trap warmth without adding excessive bulk and is usually rated in grams to indicate thermal performance. Options range from light insulation for refrigerated work spaces to heavyweight styles built for extreme cold, including subzero outdoor conditions.

Insole
Insole

When you’re looking for comfortable work shoes, you should definitely pay close attention to the insole. This is the part of the shoe that your foot actually rests on every day and is usually enhanced with extra cushioning.

  • Cushioned - Some padding in the heel, generally found in low-profile oxford shoes
  • Full Cushion - Cushioning in the heel and impact zone areas, typically found in low-profile athletic shoes
  • Extra Sushion - Maximum cushioning for maximum comfort, this is mostly in athletic shoes and styles
  • Impact Zone Padding - Extra cushioning at the ball of the foot

L

Leather

A natural material created by tanning animal rawhides and skins. There are several types of leather typically used in work and uniform shoes. Leather has high tensile strength and high resistance to flex. It can be molded and will retain its new shape.

  • Action Leather - Suede leather with a PU (polyurethane) or PVC (polyvinyl chloride) topcoat that prevents moisture penetration. You’ll find it frequently in athletic or casual shoes. It’s durable and easily cleaned, and it’s more flexible and breathable than full-grain leather.
  • Full-Grain Leather - Durable and easily cleaned, contains the full layer of leather, including the top grain and fleshy underside. Wears well and is soft and pliable. Often found on dress shoes. Commonly used for uppers.
  • Leather Outsole - Can be thin and flexible or thicker and stiffer for brogue-type shoes. Mostly used in dress footwear. Not recommended for industrial environments.
  • Leather/Suede Lining - Allows for airflow and wicking of moisture.
  • Nubuck Leather - Full-grain leather that has been sanded or buffed. Commonly used for uppers.
  • Pigskin - Leather from pigs that is lighter in weight than cow leather. It is abrasion-resistant, soft and flexible. Often used for shoe uppers.
  • Suede (Split Leather) - The fleshy underside of leather that has been split from the top grain skin layer. It is less durable than full-grain leather because it does not have the top skin. Often found on work shoes and on uppers, suede is lightweight, soft and flexible.
LINING
Shoe lining is another key to comfort. If you’re looking for a shoe that has moisture-wicking capabilities, you’ll want to look for shoes with mesh fabric linings in order to help maintain a cool, dry shoe interior. When we’re talking about moisture and feet, you know that odor is sure to follow. That’s why it’s important to understand that the proper lining for your work conditions will ultimately give you more comfort and less foot funk.

Our patented MaxTRAX® outsole is uniquely crafted to give you unbelievable slip resistance. The secret’s in the design. Maximizing the outsole surface area gives you better traction, while the precision-cut 90-degree angles channel liquids out of the tread. And since MaxTRAX® excels on dry, wet and oily/wet surfaces, it goes way beyond ASTM F2913-24 and ASTM F3445-24 slip-resistance standards.

Metatarsal guard (MG)
Metatarsal guard (MG)

Metatarsal guard shoes protect both the toes and the metatarsal bone behind the toes. Metatarsal guard shoes are required in any environment where injuries can occur to the metatarsal bone. They are most commonly used in foundries, welding, air product distribution and other heavy manufacturing. All styles marked with the “MG” icon meet the ASTM F2413-24 Mt standards.

  • External Metatarsal Guard - Can be exposed or covered, attached with rivets or stitched down after being enclosed with upper leather or some other material. 
  • Internal Metatarsal Guard - Totally secured inside the shoe.

Mesh
Makes your shoes more breathable, keeping your feet dry on the job. Tends to be found as accents on work shoes.
Microfiber
Microfiber is a thin synthetic fiber that’s perfect for shoe lining because it’s moisture-wicking, breathable, abrasion-resistant and lightweight. It’s also pliable, making it a great option for uppers too.
Midsole
Midsole
The portion of the shoe between the insole and outsole. The midsole provides the foot support, cushioning and stability. Due to recent improvements in midsole technology, your shoes are now capable of having more cushion, and more arch support. There are even ergonomic designs specifically made to decrease foot, leg and back pain.

N

Nano toe
Nano toe

PU (polyurethane)
A plastic-based material that can be made into any number of thicknesses and densities. It is widely used in shoe uppers, midsoles, outsoles and metatarsal guards. PU can be made oil, slip and abrasion-resistant. It is a good shock absorber and has a high compression set, so it holds its shape well.

Q

R

Rubber
An elastic polymer substance made from plant-based or synthetic latex. It’s abrasion resistant, shock absorbing and is long wearing. It can also be made oil and slip resistant. Used primarily for outsoles, rubber can also be combined with other cushioning materials for footbeds or molded for shock absorbent metatarsal guards.
