It is also designed with gradual pressure distribution to maximizes both comfort and warmth. Powered by a lithium ion battery, heat is supplied along the lower leg and then wraps around to also heat up the toes and the ball of the foot. The battery pack is securely held in place on the back of the sock’s double cuff.

The XLP ONE battery pack is a reliable battery that maintains up to 90% of a full charge and 90% of its initial capacity after two years of nonuse. The battery will provide continuous heating power, rather than the uneven heating output you sometimes get with other models.

Choosing The Right Boot Warmers

When choosing the right boot warmers for you there are a few things to keep in mind. You’ll want to think about how you will be using your boots and where you will be spending most of your time.

You’ll also want to factor in battery life, heat settings, installation and ease of use. When and where will you be using your boot warmers? Are you hiking, skiing, or simply walking around in a colder climate?

Someone who likes to get out there every once in a while, to local mountains, won’t need the same product as someone skiing in subzero conditions.

Battery Life And Heat Settings

Battery capacity and its duration are directly connected with temperature levels your beginners ski boot warmers will provide. Depending on the unit, you can achieve up to 22 hours of heat time on low settings, others may only provide 4-5 hours.

You’ll want to consider if the battery is rechargeable and also factor in the recharging time. Some units also include extra batteries to be sure to look into that if you know you’ll need extending heating time.

Heaters usually have multiple different heating temperatures that can effect how long the battery will last. If you’ll be spending a lot of time in frigid temps doing activities such as skiing, you’ll want a product that has a long battery life, as well as a high heating option.

You may also want to find a boot warmer that provides heat to more than just the bottom of the foot.

Installation

Also, be sure to factor in the installation method and ease of use of the product. Most units are placed in your boot with a mounted battery to the side of your boot or attached to the heating unit. Just make sure you find a warming unit that doesn’t have an uncomfortable battery location.

Some boot warmers come with a remote control so you can easily change settings, others require you to remove to boot to access the temp controls. This is a great feature as it allows you to quickly and easily access the temperature, so you can lower the temperature when you are active and increase it as you become sedentary and produce less sweat.

Operation

Every heating unit operates differently. Some come pre-packaged as socks with the warming mechanism comfortable weaved inside the material. Other options are simply an insole with a battery attachment.

New boots have the plugs already accessible and makes attachment of the battery super easy. Older models might have a little more complicated installation process as you must attach the wires to the boot with tape and strap the battery to the boot.

Comfortability

The ideal warmers should be as least invasive as possible. You don’t want to feel a bunch of additional items pressing into your foot throughout the day. However, you may notice a bit of extra material the first time you wear boot warmers. Modern ski boot heaters aren’t too heavy and you will adapt fairly quickly with use.

Conclusion

In general, the more durable the warming unit is and the more temperature levels there are, the higher the price.

However, there are still plenty of good quality to price ratio units on the market. Just be sure to thoroughly consider your needs before you purchase a unit.

If you don’t spend a lot of time in frigid temperatures, you will be able to withstand the cold with cheaper solutions.

A great pair of thick socks and a single-use heating option may be the right fit for you. However, if you will be spending a lot of hours with you feet deep in the snow, you will definitely want a more high-end unit with powerful heating options.
