When you’re planning your next hunting trip, it’s essential to ensure you’ve got the proper boots for the job. You’ll be spending hours in the great outdoors, fighting to stay warm and dry.

To make sure you can handle rain, snow, or whatever Mother Nature throws your way, it’s worth investing in a pair of insulated hunting boots.

Keep in mind that you can’t just choose any insulated pair and call it a day. The level of insulation needs to match your activity level and the environment you’ll traverse. So how many grams of Thinsulate insulation for hunting boots work best?

Boots with a higher temperature rating, such as 800g, keep your feet warmer in colder temperatures. 

Lower-rated boots in the 200g to 400g range work well in moderate temperatures at low activity levels but require more constant movement in frigid temperatures. 

Boots in the 600g-800g range are the cutoff point for high activity hunting trips. Anything heavier puts you at a greater risk of overheating.

More specialized situations in colder weather like moving through icy water or snow may necessitate moving up to the 1000g range or higher. 

This guide will help you gain a clear understanding of which boots work best for different seasons, temperatures, and environmental conditions.

Levels of Insulation

200 Grams - Great Early Season Hunting Boots

If you’re looking for the perfect early-season hunting boots, you can’t go wrong staying in the 200g range. As the lightest option available, they breathe well and provide your feet with more comfort than the competition.

They can handle constant activity but provide enough insulation to keep you warm during down periods.

The better versions of these lightweight boots will have moisture wicking technology built in to keep your feet dry when they start sweating.

The overall versatility they offer means you can use them for hunting a wide variety of game.

If the day warms up as you’re out and about, you won’t be at risk of overheating at this weight level. They’re also great for covering long distances because they aren’t too heavy. 

They can function as solid mid-season hunting boots as well. To get the most utility out of them on colder days, make sure to pair them with warm, well-insulated socks.

At this time of the year you should still be trying to decide whether to wear insulated or uninsulated boots.

400 grams - Hunting Boots Ideal for Cool Temperatures

When winter rolls around, it’s best to invest in 400g hunting boots. They slow down how quickly you’ll lose heat compared to 200g options.

The difference is significant enough to keep you warm for an entire winter day.

Because you aren’t jumping up to a much higher weight, you’ll still experience a comfortable range of motion. 

Temperatures can vary quite a bit during wintertime, and you might wonder if they’ll hold up as the weather dips.

Though they work best when it’s just above freezing, they’re robust enough to handle temperatures as low as -40°F. 

These can still work as early-season hunting boots, but you’ll have to make sure to keep your activity levels to a minimum.

800 grams - Boots for Mobile Hunters in Freezing Conditions

At 800g, we’re crossing the threshold into hunting boots for cold weather where the weight begins to limit your movement. 

This trade-off comes with enough protection to keep your feet warm on cold days.

While they still allow some mobility, you won’t want to choose a higher weight if you move non-stop when hunting. These boots are your best bet when moving through harsh environments like water or snow.

To see if these boots make sense for you, consider consulting a Thinsulate temperature chart. At the low end, they can handle days as cold as -60°F.

Their design specifications make them a popular option for bowhunters who walk for extended periods.

1000 to 1200 grams - Low Activity Hunting Boots for Extremely Cold Temperatures

Boots in the heavier weight ranges work best in niche situations. 

These are very well insulated hunting boots and their primary purpose is to protect the feet from the coldest conditions.

You’ll want to avoid these for active hunting trips due to their lower breathability and mobility levels. Tighter boots can cut off your circulation if you’re moving around too much. 

They’re your best option in situations where you need to expose yourself to severe cold temperatures. 

If you’ll be spending time with your feet submerged in icy water or trekking through dense snow, you need this level of insulation.

You’ll be wearing these boots exclusively in the winter on the coldest weather days. While lower weighted options can double as work boots, you won’t have that luxury with these boots. More activity increases your risk of sweating, which could lead to issues like hypothermia.

Rest assured that your feet will still be warm and toasty after a long day of hunting with this much protection.

Extreme Cases - 1,400 grams and up

If you’re brave enough to take on the coldest days of the year, look for boots in the 1,400 grams range (or higher.) 

Bear in mind that these restrict you to the bare minimum of activity. Their thickness prevents intricate movement.


As you can see, there’s no one size fits all solution when it comes to hunting boot insulation. Make sure to take weather conditions, environmental conditions, and how much moving you’ll be doing into account.

Lighter weighted boots are optimal for mobility and less extreme temperatures. Heavier options can handle the most extreme temperatures and exposure to the elements.

If you’re a fan of hunting throughout the year, your best bet might be buying multiple pairs for each situation.
