How to keep feet warm in work boots – Key Features of the best cold weather work boots
Keeping your feet and toes warm when walking in snow and on ice seems difficult but it is possible. It is actually easier to do if you are active vs sitting or standing still. So make sure to move as much as possible although it might not be comfortable. This is a good start how to keep feet warm in work boots.
One of the most critical aspects to warm feet in your work boots is keeping your feet dry. Make sure your work shoes are waterproof. If they are only water resistant, make sure you stay out of snow. However it would be best if you waterproof your safety shoes for winter to ensure the best chances of warm feet.
Steel vs Composite Toe Caps
This is an easily overlooked detail that could make a big difference on how warm your toes are in your safety shoes.
The steel toe is affected by temperature much more intensely than composite material is. This means that the metal gets very hot by absorbing heat in hot weather and very cold in cold weather.
The composite material does not let the temperature affect it in the same way. Composite toe caps offer a much better protection layer to keep out the cold, or the heat, depending on the weather outside.
With cold weather comes snow and ice. If you work outside and need to walk on snow or icey areas, you need to pay attention to your outsole.
Does it have a deep treat to avoid snow collecting in your boot? Snow will fill shallow tread more easily, resulting in less grip when you walk. This could lead to slipping and falling. Examine different tread patterns and choose the one that has lugs that provide traction by locking with the ground. This will help you avoid fatigue as you will not need to use additional energy to keep your balane on slippery surfaces.
Not only do you need a deep, agressive tread for sufficient traction, but the material is also important. Rubber has a much better grip factor compared to a mixed carbon and rubber sole.
Slipping (and falling as a result) in one of the most common and dangerous workplace accidents. Make sure your outsole is specifically designed for slippery winter conditions and is suitable for snow and ice work.
Foot, Ankle and Arch Support
Even with soles that have great grip, you might still step on an icy patch unexpectedly. This is when you need your ankles to be protected with high cushions. This will not only help you potentially avoid a fall but also protect your ankle from getting hurt unnecessarily.
A fiberglass or nylon shank will provide additional support on uneven ground. Avoid the steel shank as this transfers cold and will decrease the temperature of your boots drastically in winter.
Arch support is not specifically winter related. Infact you want to have arch support year round. If your boot doesn’t have a suitable insole included, you could get one designed to offer extra insulation warmth for both winter and arch support at the same time.
Depending on how cold your winter gets, you can choose between different levels of insulation. The lowest level of insulation is 200 grams. This is a winter boot for standard winter weather and it the usual solution how to keep feet warm in work boots.
If you work in an area with bitter cold winters and you need your safety shoes to be as warm as possible you can get boots with 1200 grams of insulation. These boots are meant for the coldest of cold situations and would heat your feet to an uncomfortable level in “standard” winter weather.
If you are outside for extended periods of time, you would want to opt for a boot with a higher level of insulation.

1000 gram insulated work boots
The most common insulation material used in work shoes is Thinsulate™. This is a product developed by 3M™. 3M™is an American multinational corporation and one of their specialisations is in the worker safety field.

What is the insulation made of?
Thinsulate™ insulation is a very thin material at 0.00059 inches in diameter. This makes it thinner than polyester and other similar fibers, and is therefore more dense and effective at retaining heat. It has a design allowing moisture to evaporate and escape while keeping warmth in.
Tests have shown this material is 1.5 times warmer compared to down and surprisingly double as warm when compared to other insulation materials. This material retains its thermal benefits even when wet. It is a highly resiliant material and durable that will see you through multiple winter seasons in a good quality boot.
With Thinsulate™ it is possible to keep the boot lightweight because it is such a thin material, you can fit a larger amount of it into the shoe lining, allowing for an extremely well insulated winter safety boot.

200 grams is the standard most people will feel comfortable in. This insulation level is for people spending a limited amount of time outdoors in the winter.

400 and 600 grams is designed for working people who are outside for extended periods of time or who might not be active when outside. If you are standing still or sitting, your body generates less heat and so you will get colder vs if you were generating warmth by being active. Suitable for approximate temperatures between 0 – 30 degrees.
800 and 1000 grams of insulation in your work boots is suitable for temperatures under 0 and colder. If you are working in these extreme conditions, make sure you wear wool socks and not cotton.
