Ah! The mist rises. I didn't get that you were talking about heated socks. Glad you've found a way to keep your feet warm.I am pleased to announce that they were delivered today and I immediately put them on trial. The batteries come with 4 power output settings. On the highest setting the claim is that they will last for 3-3.5 hours. On the next setting, 4-5 hours. Next 6-8 hours and on the lowest setting, 15-18 hours. I've just run the batteries down having been wearing the socks for 7 hours on the 2nd lowest setting, so the claim is about right. For the first 3 hours I was in my work boots in the workshop with the log stove going. Normally in this situation I would come back indoors feeling generally warm but with cold feet. This evening I am looking forward to going to bed with warm feet - a luxury I haven't experienced in winter months for a good few years.
Whatever the Amp.Hour rating is the socks HAVE kept my feet, not just my toes. for many hours.
I have been told I have Raynaud's syndrome, which affects blood flow in my fingers and toes, so it's a real problem keeping them warm in winter. I find if I keep my body core really warm, I don't suffer frozen fingers and toes so badly. I wear lots of layers of clothing. I wear thermals at this time of year, body warmers, neck warmer, hat. It all helps. Eating well has a surprising effect. as soon as I get hungry, I start getting cold. I don't wear gloves in the workshop, too dangerous around machinery. In the garden, I wear thermal lined waterproof rubber gloves. They are great.My difficulty in the workshop (unheated garage) is cold fingers when the temperature drops. I cannot find any thermal gloves which allow me to work satisfactorily (too bulky)
Wear a top-hat & you can keep a flask there as well!I was told some years ago on an Outward Bound course that you lose 10% of your body heat through your head, never seen any scientific proof but you do feel a lot warmer when wearing a hat .....................(if you wore a Bowler you can keep your sandwiches inside )
