Introductory set of 2 x hands and 2 x feet warmers

Children, the elderly and disabled people should use this product with care and under supervision.Seek the advice of a doctor before use in cases of diabetes, delicate or sensitive skin, blood circulation problems, paralysis or damaged nerves, rheumatoid arthritis, if you are pregnant or if you have any doubt.Do not apply to frostbite or desensitised skin.Do not use while sleeping.Do not use at the same time as external analgesics or other heating devices.

A little like a fire, a combustible (iron powder/active carbon mix) and a combustive (oxygen in air)are required.So the reaction stops_when there is no more active carbon (definitive stop after approximately 5h_or in an airtight environment (in a rubber boot or with neoprene cycling overshoes). The interruption is temporary = if you give the warmer more air, the reaction will start up again.

To keep your feet nice and warm with these foot warmers, you should know that the_exothermal reaction starts on the production line,_there is a 100% check of the active mix,_then only at the end of the line the foot warmer is inserted in the plastic packaging that stops the reaction and therefore heat production.It will start again when the pack is opened, with oxygen and humidity.

1. Remove the warmer from the bag and knead it to start the heating process with the oxygen and humidity in the air,2.wait 10 minutes as the HEATER MUST BE WARM before enclosing it in your boots.3. ideally open it in an environment with an ambient temperature of 20°C (at home, in the car, etc),4. although activating it at 0°C is possible, you will have to wait longer for the warmer to be hot.

The reaction stopped due to lack of air.Remove the warmer from the boot and give it more air, knead it between your fingers to warm it faster and place it back in your boot only when the T° has increased well.There is nothing more frustrating than being cold during exercise, and then once you are home, having a warmer that heats up again and throwing it away when it is burning hot.

2 situations should be avoided:_ Never place the pad directly on the skin.Ideally, outside the sock, and depending on the type of boot or shoe volume, on the top of the foot or under the toes._Do not use the warmer and another heat source (for example: do not keep the warmers on after the sporting activity, in the car, when the heating is blowing on the feet).

_if there is no air around the warmer : enclosed in a neoprene shoe cover or in rubber boots, ..._in extreme conditions: In very cold weather, the warmer provides extra warmth in addition to the T° it is used in, but unfortunately, if the T° is too low, it has trouble_in very high altitude: > 3000 m, the lack of oxygen limits the reaction.
