Warm up in frosty weather with 2E chemical warmers

Unique size warming insoles for feet: size 43-47
2E thermochemical warmers will help prevent frostbite, warm you up when it's absolutely necessary, and make you feel more comfortable in the cold. The product is indispensable in field conditions and will be useful for lovers of active winter recreation, tourism, and fishing.
Oxygen activation
The warmers are very easy to use, but certain recommendations and rules must be followed to achieve maximum effect and avoid harm. To use the warmers, simply open the package, remove the product, and wait a few minutes for oxygen activation (a chemical reaction occurs), after which the insoles can be placed in shoes.
The products are filled with a special mixture that emits heat upon direct contact with oxygen.
Ingredients include: iron powder, water, vermiculite, activated carbon, salt.
Up to 8 hours of warmth
2E chemical foot warmers are a single-use personal product for localized foot heating.
The product length is 283 mm (size XL). After activation, the operating time is up to 8 hours. The average temperature of the warmer is approximately 40 °C, but the maximum can reach 45 °C, so the product may cause heat, and in case of excessive use, it may cause localized burns or skin irritation. Important: if the insole is too hot or simply uncomfortable during use, remove it immediately.
The warmers do not require special disposal measures; after single use, cold warmers can be disposed of as regular household waste.
Functionality and versatility
Chemical warmers are a "must-have" during cold weather. Of course, such a product is primarily essential for military personnel, but warmers can also be used for sports, tourism, fishing, etc.
2E thermochemical warmers are one of the effective means of heat generation. Such personal heating devices are extremely practical and comfortable, but it is important to follow the rules of use. Each type of warmer is designed taking into account operating conditions.
Insoles cannot be used for other body parts – only in shoes, as there is significantly less oxygen there, and if such an insole is used in areas with greater oxygen access, the chemical reaction will be much more vigorous, heat will be released much more actively, and this can lead to burns.
Medical warnings
Users with allergies, diabetes, frostbite, scars, open wounds, bruises, swelling, sensitive skin, arthritis, paralysis, nerve damage, or circulatory problems, as well as people who cannot apply or remove the warmer themselves, are not recommended to use the warmer unless prescribed by a doctor. In addition, contact of the package contents (powder) with eyes, mouth, or uncovered skin must be avoided. Furthermore, it is not recommended to use the product while sleeping, with other heating devices, and not to heat it in a microwave oven.
