Andrew, The battery-powered socks are an option. So are the chemical heaters. The latter can be used inside your current boots. They work on the principal of oxidation. You can also use them in your pockets, inside your sleeping bag, etc. A larger patch (with adhesive side) can be worn across your lower back. All of your blood flows through your kidneys quite regularly (hopefully) and this helps maintain warmth. Don't forget a hat too. Cabelas carries these heaters, as do most outdoor outfitters. http://tinyurl.com/ynzhvq Peter ----- Original Message ----- From: "Andrew Goodwin" <a.goodwin1@xxxxxxx> To: <az-observing@xxxxxxxxxxxxx> Sent: Monday, January 15, 2007 12:30 PM Subject: [AZ-Observing] Cold Feet I need information and help to keep my feet warm. I know that this is a problem for many thus I am posting to this listing. After being frozen out at Flat Iron on the 13th (I know we were experiencing record temps) and I was wearing moonboots with two pairs of wool socks I went to Cabela's and was directed to a sock made of a fabric called Polar Tek. does anyone know about the new fabrics or a boot that will keep my toes from becoming numb? I have read the web site article "Keeping Warm". http://www.saguaroastro.org/content/keepwarm.htm Perhaps it needs to be revised to indicate the new products on the market today. Any input would be appreciated. You may also post to me off list. Clear Skies and thank you in advance. Andrew Goodwin PS My moonboots did not come with wool liners and I can't find any at Cabela's or Sportsman's Warehouse. . -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list. -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
