The right hunting boots can make or break your hunt, especially during the cold weather season. When you’re looking to purchase insulated hunting boots for mountainous terrain or the warmest rubber hunting boots, you need to consider the season, area, and type of hunt you’ll be on before purchasing your footwear. Here are some things to keep in mind when choosing between insulation levels in a hunt boot:

  • Season – Are you looking for boots you can wear year-round or are you specifically looking for the warmest hunting boots for winter? Will you be actively walking through deep snow or are you spending your winter hunting in southern states? The level of boot insulation you need will vary if you’re planning an expedition in Wyoming vs. Georgia.
  • Types of hunting – Big game, small game, elk hunting, upland hunting – the type of hunt and the distance you’ll have to walk will impact the level of insulation and type of hunting boot you’ll need to stay comfortable and warm.
  • Hunting Method – Will you be using a gun or bow? Tree stand hunting or trekking through fields? Which approach you take on your hunt can determine whether you’ll be seeking out your target or waiting for them to come to you, and how close you’ll need to be to get in a good shot. Because of the incredible sense of smell deer and other hunted animals have, what you wear on your feet can make the difference between getting close enough for a good shot or scaring off a potential animal. Wearing insulated rubber hunting boots will help keep your scent from spreading across the ground while you walk, while leather hunting boots won’t mask human odor and can send your target in the opposite direction.

Which Insulated Hunting Boots Do I Need?

Whether you choose to hunt in spring, fall, or the dead of winter, the right insulated hunting boots can make a world of difference. We know, because a lot of our team is made up of avid hunters and outdoor enthusiasts. When you work hard during the week, you deserve to play hard off the clock, so whether it’s ice fishing or early fall hunting trips, we can help you learn how to choose the warmest hunting boots based on boot insulation levels.

Hunting Boot Insulation Explained

Now that you’ve considered some vital questions, let’s look at hunting boot insulation levels. Boot insulation varies in quality and, for comfort and usability, maintaining warmth without bulk is ideal. You’ll also want to consider activity levels since less insulation is typically needed if you’ll be actively moving and walking, while more is needed for stationary activities.

Pro Tip: Everyone has a different internal thermometer. What temperature and condition we think is “cold” will vary, as does our body’s circulation and comfort levels.

Boot Insulation Gram Chart

Keep in mind that these are general guides and that everyone will feel cold differently. The chart below shows different boot insulation weights in grams and a general guide for activity and weather types to help you choose the warmest hunting boots for your situation. If in doubt, we’d choose the higher insulation level so you can wear your boots longer into the season and supplement with warm socks if needed.

 Boot Insulation Levels  Hunting Days & Activity Levels  Recommended Hunting Boot
 200g  Mildly cool spring and fall days or evenings with higher activity levels  1957 Series Flyway (Non-insulated)
 400g  Mildly cooler days with moderate to little activity  Crosstrek Waterproof Hiker
 600g  Cool days with moderate to little activity  Infinity FD Mossy Oak Rubber Boots
 800-1000g  Colder late fall and early spring days with light activity  Infinity FD Series Outdoor Boot
 1200g  Early winter days with higher activity levels  We’d upgrade to 1500g boot and wear these into the winter

What Kind of Insulation Do Thorogood Hunting Boots Use?

What is Thinsulate™?

Thinsulate™ is the most frequently used type of boot insulation. Made by 3M, the synthetic fiber thermal insulation is used in clothing and footwear. Since it’s thinner than polyester fibers, it’s less bulky than other insulation types and also has waterproofing qualities. Fun fact: Thinsulate™ is also used in fabric roofs on sports cars (Porsche Boxster) to reduce heat loss and noise levels, as well as in upholstery.

How is Thinsulate™ measured?

Thinsulate™ is measured by weight, more specifically in grams per square meter of insulation. Thinsulate™ in boots typically ranges from 200g to 2500g.


SOLARCORE® is NASA-inspired aerogel that is proven to retain 50% more heat and is designed with minimal bulk to block the cold. The same science used to insulate spacecrafts on voyages at -450°F is now used in apparel and footwear (so don’t complain to us your feet are cold with it because it definitely doesn’t hit -450°F!)

How is SOLARCORE® measured?

SOLARCORE® isn’t measured in grams the way Thinsulate™ is. It’s formed in one 2mm thin layer and is added below our boots’ footbed to form a cold-stopping barrier between the sole of the boot and the footbed. It’s also added to the toe cap, protecting your toes and creating a barrier on the bottom of your feet. Thinsulate™ paired with SOLARCORE® creates the ultimate insulated hunting boot to protect you on your outdoor pursuits. Say goodbye to numb toes!

Tips for How to Keep Feet Warm While Hunting

Choosing the warmest hunting boots and higher insulation levels is our number one tip to keeping your feet warm while hunting, but there are a few other ways you can stay warm in the winter.

  • Upgrade your sock game to merino wool or a performance material that will wick away sweat
  • Try putting cotton balls between toes to insulate each one individually
  • If you’re staying stationary, use cardboard or an insulated mat to keep the freezing ground from leaching cold into your feet
  • Avoid metal conductors like steel tree stands or seats and use cardboard or another layer between yourself and a metal object
  • Avoid staying stationary for too long – loosen your boots so you can wiggle toes or ankles and keep the blood flowing to your feet
  • Use small heat packs as feet or hand warmers
  • Make sure your boots aren’t too tight since it’ll restrict blood flow
  • Use an antiperspirant on your feet before you go hunting
  • Bring spare socks in case your feet get wet or sweaty
