Foot warmers offer seven hours of warmth

Ergodyne has introduced N-Ferno® disposable foot warmers (model 6995). The disposable, one-size-fits-all foot warming pack provides additional heat inside footwear.

Workers activate the foot warmers by opening the pack. The all-natural ingredients heat up quickly as soon as they come in contact with oxygen and can keep feet warm for up to seven hours. They can be placed in a resealable plastic bag for reuse the next day.
