These heated insoles were purchased for my girlfriend who works in an unheated farm shop and suffered terribly with cold feet. Not any more! These socks are a miracle and are powered by AA rechargeable batteries from the pound shop.
She wears them whenever it's cold now and says they really do the trick!
How do they work?
The insoles feature an advanced battery operated heating system, which circulates gentle warmth around the feet running down the whole length of the foot including the toes - which are the areas most prone to the cold.
Supplied with battery boxes and garters to attach to your leg. When switched on, they will heat your feet up quickly yet gently with over 3 hours of hot time from good quality batteries. This time can be dramatically increased if you only have them switched on for short bursts.
