4 Best CSA Work Boots

If you want great protection from your Personal Protective Equipment, looking for CSA-approved and ASTM compliant safety work boots will be your guide to assured safety capabilities.

In North America, the CSA is a certification entity that tests for safety standards, including the workplace.

When manufacturers of footgear produce their work boots, a CSA-certified rating will mean that a specific work boot offers specific measured safety features.

After lots of research and on-the-job testing, we selected the Carharrt Six-inch Men’s Rugged Flex CSA Work Boot as our overall pick for the best CSA work boots. What convinced us? The Eva cushioned footbeds, a “Storm Defender” boot waterproof membrane, and the Swen Flex PR puncture-resistant plate in the outsole. This boot also boasts 400 g of Thinsulate insulation. 

Another pair of CSA work boots that got our attention and should get yours is Nat’s Waterproof CSA S620 Work Boot. It’s expensive, but certainly a high-quality boot, especially for those in need of EH protection.

CSA refers to the CSA Group which was formerly called the Canadian Standards Association. This is an entity that develops safety standards in approximately 57 different product areas. This organization finds industry, consumer, and government representatives among its members.

The Group got its start in 1919 as CESA or the Canadian Engineering Standards Association and was created to establish standards. When a product carries the CSA symbol, it means that it has undergone independent testing and complies with recognized safety standards

The adherence to the majority of these standards is completely voluntary on the part of manufacturers, but this voluntary choice is highly respected because it means that the product had been tested independently for safety performance, and CSA markings are registered. This means that these markings can only be applied by someone licensed to do so by CSA.

CSA also has a sister company called CSA International that is a testing laboratory that is internationally recognized. Often manufacturers may opt for this entity because local legislation requires safety certification.

CSA Markings

The CSA marking or rectangle on a work boot indicates some safety feature present and tested in or on the work boot. CSA features various safety patches that indicate differing features. Among these, we find:

CSA Green Marking

CSA Green Marking Boots

If you find a CSA Green patch on your work boot, this indicates that the boot has both a safety toe and offers puncture-resistant protection. These features are often required by employers at industrial settings or construction sites.

A grade 1 protective toe cap means that your boots will protect your toes from impact injury in the event that heavy tools, materials, or heavy debris fall onto your feet. These safety toe caps may be made of composite materials, alloys, or steel and should protect up to 120 joules.

The puncture-resistant outsole should be able to resist forces of 270 pounds or 1200 Newtons. Puncture-resistant soles can feature steel or composite panels or plates to protect feet.

CSA White Marking

CSA White Marking Boots

A white CSA rectangle patch tells you that the work boots’ outsoles are EH or electrical hazard proof. They will withstand charges up to 18,000 electrical volts and offer ImA current leakage for approximately sixty seconds.

CSA Blue Marking

blue square with the letter R footwear meaning

The CSA blue rectangle indicates that the work boot features a protective toe cap rated Grade 1 that can resist 125 joules.

CSA Yellow Marking

yellow square with the letters “SD” footwear

The Yellow rectangle patch from CSA that includes a grounding symbol and a green SD, tells you that this pair of work boots come with outsoles that dissipate static. These soles will be manufactured in an anti-static material and help to control electrostatic charges.

How Do You Choose?

Before even seriously considering any pair of safety work boots, check to see if they feature a CSA safety rectangular patch, its color, and what the safety marking indicates.

The precise safety patch that you need to look for should represent the safety standards for your work environment.

Other Features to Consider

The purchasing of a safety boot is an investment of your money made for your protection. Other features to search for when making this important investment include:

#1. Construction and Durability Features

Together with premium materials, the construction method used in producing a work boot will influence durability. Weight and boot flexibility will be affected.

The three construction methods used most commonly for the attachment of boot uppers to boot outsoles include:

1.) Cement. A simpler and less expensive method that glues boot uppers to outsoles with industrial-grade adhesive. As the glue deteriorates, durability lessens.

2.) Goodyear Welt. Renowned for its durability, this is a water-resistant technique. The outsole is connected to the upper boot with leather, plastic, or rubber.

Boots using the Goodyear welt construction process are more expensive but allow for repair and the replacement of outsoles.

3.) Molded. Here, an injection technique is used to join the boot components. Stitching and adhesives are not employed in the construction and the binding is resistant to water. They cannot be repaired, so once they are worn down, they will be tossed.

#2. Resistance Capabilities

A priority when choosing work boots will be oil and slip-resistant outsoles for increased traction. Outsole tread should feature shapes and designs that afford a better grip on uneven terrain or slippery surfaces. Designs will vary and may include squares, circles, triangles, or hexagons.

The spaces between the tread design need to adequately channel any water or liquids outward to boot sole edges. When fluids remain trapped underneath an outsole, this can cause you to slip.

The tread thickness is likewise important. Thin tread that wears too quickly, will reduce resistance to slippage. 

#3. Comfort Features

Shock absorption is an important comfort feature when selecting a work boot. Some boots will have specific features integrated into the design to prevent foot fatigue and increase comfort during long work shifts such as insoles with exceptional cushioning and midsoles that are designed to absorb shock during walking and movement.

A breathable moisture-wicking work boot will offer air ventilation and contrast perspiration leading to odors. Sweaty feet all day and the bad smells will lead to discomfort.

Breathability increases air circulation to assist moisture-wicking boot liners to keep feet dry. This prevents chafing, blisters, and undesired fungus.

#4. Waterproofing and Insulation

Waterproof boots can determine if your feet remain dry depending on where you work and what type of inclement weather you may be exposed to.

Some boots feature a waterproof membrane that will add some cost to the price, but, if you must work in extreme meteorological conditions, it might be wise to invest in a more expensive work boot. 

If you work in conditions that expose you to bad weather or frequently walk on surfaces that have water or liquids present, select waterproof work boots.

Insulation is important for workers in colder climates and that work specifically outdoors. This feature is not optional.

Depending on the kind and amount of insulation a work boot may seem bulkier and heavier, but with new insulation materials, the difference may very well be minimal.

#5. Weight

Heavy boots can add to the strain of the feet and legs which can lead to discomfort. Lightweight boots can be of great benefit if you are on your feet most of the day.


When looking for a top-quality brand-name work boot with optimal puncture resistance and a protective safety cap, you can’t do better than to look for CSA-approved safety work boots.

Look for the color-coded CSA rectangular patches to guarantee your safety every day of the week that you are on the job.
