This item has a bad description title... Buyer Beware!
They are not "rechargeable" they have to be plugged in to work. I have had heated insoles before and they were expensive so when I saw these I thought "too good to be true" but why not try?!? My bad on not reading the description more carefully but calling these rechargeable is like saying the kitchen toaster is rechargeable....no it is not rechargeable, just because it is not totally cold the second you unplug it does not make it "rechargeable" it will be cold in a minute and so will these inserts. In the title it says "Winter hunting skiing fishing hiking". I "charged" them and by the time I walked from the bedroom to the kitchen (the kitchen is in the same small house, not in another town) not only were they no longer warm they felt cold. Maybe the author of the description goes fishing in a tank next to the computer indoors but most people take the item description to mean they will keep your feet warm while you hunt and fish etc. outdoors. I don't hike or ski. Do you guys carry USB battery packs or maybe a generator on the slopes? All of that being said I can put them in bedroom slippers and sit at the computer with them plugged into the computer and have warm feet but I won't be walking around with wires coming out of my shoes plugged into a battery in my pocket. I would not have purchased them had I known. If you want warm feet outside warming your shoes and socks with a blow dryer before you put them on would likely work as well.
