***Here’s my advice. If you want a quick understanding of what type of insulation may be best for your work boots, then watch my short 45 second video posted below that quickly explains what you need to know. Also, please subscribe to my YouTube channel by clicking the button below. Thanks!

As you can see, some of the boots above are outdoor gaming boots that also can double as rugged work boots. As I mentioned at the top, a large majority of work boots stop at 400 grams of insulation.

Yes, there are exceptions. Rubber work boots go well past 400 grams of insulation. But if you are looking for 1000 gram insulated work boots, most boot companies have, at best, limited options.

Thinsulate is very useful in boots and outdoor gear because it is extremely warm despite being non-bulky and lightweight. It is made and trademarked by 3M (source). The microfibers trap in heat, but don’t take up a lot of space and don’t add much weight.

Although most of the options on our list use 3M Thinsulate as insulation, it’s important to note that the Danner Men’s Alsea boots use PrimaLoft instead. Danner, as is the case with many brands, will use both Thinsulate and PrimaLoft as insulations for their footwear.

Although 3M Thinsulate is more common, PrimaLoft is another popular type of synthetic insulation, and is very common in both outerwear and boots.

In my experience, Thinsulate seems to be a thinner, less bulky insulation, almost like a lining, while PrimaLoft feels a bit bulkier or “fluffier”. Both are warm, but if you are interested in these Danner boots, I’d recommend contacting them to see if they can give you more information.

Let’s start by discussing what you can expect when you wear a pair of 1000 gram Thinsulate work boots. If you think 1000g boots might be too warm, visit our article about the best 800g insulated work boots or our article about the best 600g work boots.

1000 Gram Thinsulate Boots Temperature Rating

Disclaimer: We cannot make guarantees about the temperature ratings of the boots mentioned in this article. Our recommendation is to contact the companies directly for more information. We also cannot make any guarantees about the suitability of these boots for your job. All jobs are different, and all boots are different.


For the continental 48 US States, 1000 gram boots will be warm enough for most jobs (and may be too warm for some). There will be a few exceptions, and if you work in dangerously cold conditions, you may need to go higher. But for most jobs, 1000 grams will be warm enough.

For comparison, the large majority of winter hiking boots use 200 grams of Thinsulate insulation. Now, it must be noted that hiking is an active exercise, which doesn’t need as much insulation, but using 1000 gram Thinsulate for footwear is recommended for extremely cold, severe conditions.

winter-work-boots

Most people who turn to 1000+ Gram insulated boots are operating in cold, wintry conditions, with a low activity level. But exactly how cold? What is the temperature rating for 1000 gram insulated boots?

Unfortunately, most boot companies do not provide a temperature rating for their boots. This makes it difficult to say how warm a boot is because there are other things besides Thinsulate that can affect how warm a pair of boots is.

Most companies choose to leave off a temperature rating to avoid any legal issues that may arise from it. Also, not all 15 degree days are the same. Is there wind, ice, snow? It’s impossible to guarantee temperature ratings in boots, so most companies just avoid it altogether.

That said, we can get a pretty good idea what the appropriate comfort range for 1000g insulated work boots might be by looking at the suggestions some of these companies make, then applying some reason on top of that.

1000g Comfort Range

Some companies will use a “comfort range” or a “comfort zone” to kind of give you a general hint of what the temperature range might be, without making a specific temperature guarantee. This may vary by company, but I believe most companies do not consider the comfort range (etc) to be a guarantee of any sort.

Again, as we mentioned above, for the temperature rating or comfort rating of a specific boot, we recommend contacting that company directly for more information. The rating that one company puts on a 1000 gram insulated boot does not mean the same rating applies to 1000 gram boots made by other companies.

But if you are just looking for a general understanding of the “comfort” range that some companies use for 1000 gram boots, there are a few companies that supply that information.

  • The Lacrosse boots we have linked above in the article (style 376029) have a “comfort zone” of -60 degrees F to +30 degrees F (source). But we also need to remember that those Lacrosse boots are made for harsh outdoor climates. This range should not be considered 100% applicable to all boots on our list.
  • The RefrigiWear Platinum Leather boots on our list (style 123CR) have a suggested “comfort range” of -35 degrees F to +15 degrees F (source). As you can see, the suggested range can change significantly from company to company, and boot to boot.

Again, those “comfort” ratings should not be thought of as a guarantee. I actually appreciate the companies, like Lacrosse and RefrigiWear, who will stick their neck out a little bit and give you information like that.

Like I mentioned earlier, these companies take on a bit of risk to provide us those details. But as a customer, it is very helpful to have an idea where a boot might fall regarding a temperature range. So, thank you Lacrosse and RefrigiWear.

How active your job is will greatly impact the weight of insulation you need. In general, 1000 gram boots are suitable for extreme cold, but if you work in dangerous sub-freezing weather all day, depending on how active your job is, you may need to consider going even higher. Nobody knows your work environment better than you.

The main takeaway is if you’re looking for an actual temperature guarantee, those basically don’t exist, and we certainly can’t give one either. Most companies won’t make themselves legally vulnerable by placing a temperature guarantee on a product.

Unfortunately, as I have learned, sometimes it’s just trial and error to find the boot that best fits your winter needs.
