How do I activate and place the heaters on my feet?
To use the heaters correctly, please read the instructions supplied with the product carefully.
Remove the heater from its packaging, in an environment of around 20°C (home, car, etc.). It activates on contact with air.
At 0°C or 2000m altitude, blow several times on the warmer to activate it.
When the warmer is warm, after 10 to 15 minutes, remove the adhesive strip and stick it on the sock at toe level, before putting your shoes back on.
What precautions should I take?
These heaters are for feet only and must not be glued directly to the skin or any other part of the body. Do not place them on the instep, they must not be compressed. Do not apply to thin socks or tights. Do not wear with sandals or rubber boots. Do not use while sleeping. Do not use with cosmetics or other heating devices. Do not place 2 heaters on the same foot.
What are heaters designed for?
These warmers are for cold-weather use only, and should not be used near heat sources such as car heaters or fireplaces. They are not designed for intensive sports use, and should be avoided in case of perspiration.
When using them, make sure that the warmer does not slip on the instep.
If the warmer feels too hot, or if you experience any unpleasant sensation, irritation or redness, remove it.
