WONDERFUL
I have extremely cold feet, and have tried most products to keep my feet warm.  Including three different and expensive ones from Sharper Image.  By far this products is awesome.  They are well made, very comfortable, and easy to use!  I didn't know how it would feel with the battery on the top of the foot, no problem at all!  (The ones with the battery on the side are uncomfortable and bother my ankle bone.)<br /><br />For my chronic cold feet condition, I'm so desparate paying the money is a non-issue.<br /><br />I bought the battery operated insoles for shoes for when I leave the house.  What a pain in the butt, they never worked right.<br /><br />For years I've been buying World-Bio heated insole foot warmers, 40 at a time, several times a year.  It's expensive, but I cannot live without these.  I have one in my purse and in my car.  Talk about addiction!<br />Without them I cannot think straight or sleep.  Doctors cannot find a cause for my cold feet, in an otherwise healthy woman, but I believe it has something to do with the thryroid medication I must take.<br /><br /> I would not hesitate to buy these again.<br /><br />Cold in Southern California!
