Winter Boot Insulation Guide

Winter Boot Insulated Guide: How to Pick the Correct Boot For Your Position During the Winter

Are you working outdoors this winter? Keeping your feet warm in the winter is an important factor in overall safety and comfort on the job site. Extreme cold can cause a number of health problems for employees during the winter months. Hypothermia and frostbite are just two conditions that may affect workers if the proper precautions are not taken.

The best way to keep your feet protected from frostbite is by investing in a pair of high-quality boots that are well insulated. The question is how much insulation do you need?

Boot Temperature Ratings Explained

A lot of the winter boots we carry do have specific temperature ratings but some brands are moving away from temperature ratings because there are a lot of assumptions that go into the ratings. For example, temperature ratings are based on assumptions that the wearer is moving around consistently or that they’re foot is completely dry. These different factors can affect the overall performance of the boot.

Different Types of Boot Insulation

Brands can use different types of insulation based on styles or they can develop their own proprietary insulation methods. 3M Thinuslate™ is one of the most common types of insulation. It is warm yet lightweight, the extremely fine microfibers in Thinsulate™ insulation helps trap air and block body radiant heat loss, making it an efficient insulator. 

What does “grams” of insulation mean?

The amount of insulation refers to the thickness of the insulation used, not the total weight of insulation in the boot. For example 200 grams of insulation means 200 grams per square meter.

200g Insulation

Temperature Rating: -28°C/-20°F
Season: 3-Season
Works best for cool temperatures and little to no activity, or for high activity levels in cold weather.

400g Insulation

Temperature Rating: -40°C/-40°F
Season: Winter/Freezer Work
Works best for cold temperatures when doing moderate activity.

600g Insulation

Temperature Rating: -51°C/-60°F
Season: Winter
Works best for colder weather conditions and low activity levels.

800g Insulation

Temperature Rating: -62°C/-80°F
Season: Winter
Works best for very cold weather and low activity.

1,000g Insulation

Temperature Rating: -73°C/100°F
Season: Winter
Works best for extreme cold weather conditions with very little activity.

Different Types of Boot Insulation

Go with a Composite Toe.

Steel toe boots might be classic, but metal is a conductor so you will feel the cold a lot more with a steel toe. Composite does not conduct hot or cold but provides the same level of protection as steel.

Wear Moisture Wicking Socks.

Wool or synthetic socks work best, avoid fibres like cotton since these are very absorbent and can cause discomfort when wet. Check out the Wool Socks we carry here.

Consider Breathability.

Look at the lining of the boot, you want a boot that promotes a breathable lining to prevent humidity and sweat in your boots.

Dry your boots.

This goes without saying, it is important to dry your boots after work (even if they don’t get super wet) to prevent moisture from building up within your boots.

Height matters.

If you a trucking through snow it is important to get a taller boot that helps keep snow out of your boots. Baffin has a great selection of taller winter boots (8+ Inches).

How do I make sure to get the right size?

To measure your feet:

  1. Get a blank piece of paper, a pencil and a tape measure.
  2. Stand with one foot on the piece of paper, and have most of your weight on your foot to simulate walking.
  3. Holding the pencil perfectly vertical and perpendicular to the paper, mark a line at the back of your heel and at the tip of your longest toe. Also mark a line along each side of the widest part of your foot.
  4. Measure length and width to the nearest 16th inch and subtract .20 to .25 inches, or .50 centimetres, to account for the width of the pencil.
  5. Find your corresponding size in the charts below.

A couple of tips to get the perfect fit:

  • Measure your feet later in the day as feet normally swell and can become up to half a size bigger in the evening.
  • Measure both feet and use the measurements of the biggest foot. Many people have feet that are different sizes.
  • Wear the same type of socks you will generally be wearing on the job when you measure your feet.

Here are some general guidelines to assess fit once you’ve received your new boots:

  • Try on new boots towards the end of the day.
  • Walk around in a clean environment for a couple of hours to make sure the boots are comfortable.
  • Try boots on both feet, as many people have feet that are different sizes.
  • Boots should fit snugly around the heel and ankle when laced.
  • The inner side of the boot should be straight from the heel to the end of the big toe.
  • The boot should grip the heel firmly.

Hint: For the most accurate results, measure yourself in your undergarments.

  • Neck: Measure around the base of your neck, inserting your forefinger between the tape and your neck to allow ease in fit.
  • Chest: Measure around the fullest part of your chest, keeping tape firmly under your armpits and around your shoulder blades.
  • Waist: Measure around your waist, slightly below your natural waist, where you normally wear your pants. Insert your forefinger between the tape and your body to allow ease in fit.
  • Sleeve length: Bend your arm slightly. Measure from centre back neck, across your shoulder, down to your elbow, down to your wrist.
  • Hip: Measure around the fullest part of your hips, inserting your forefinger between the tape and your hip to allow ease in fit.
  • Inseam: Measure a similar pant that fits you well. Measure along the inseam, from the crotch seam to the bottom of the hem.

Between sizes?

If your measurements are in between those listed in the size chart, pick the next larger size.
