Been using these for years for all sorts of cold weather activities. Small heat generating packets that fit in your shoes or mittens.
Toe warmers are to be worn between your socks and your shoe. The trick is to use a medium to thick sock. Directly against the skin or wearing a thin summer sock could result in too much heat.
The hand warmers can be placed into your mittens. Haven’t figured out how to use them with gloves. The challenge with gloves is keeping the finger tips warm.
In my area of the cold upper Midwest they are sold everywhere, sporting goods, hardware stores, even convenience stores. Can be purchased individually or in packages.
This is Amazon link so you can get a better idea. Many different brands too.
