Space age reflective technology keeps feet warm, even in the coldest winter weather.
Reflects body heat back to the foot.
Aluminized reflective film with durable reflective coating. Trim to shoe size. Lasts one season.
One size fits all (cut to fit).
This product is worthless! Bought it to wear working at night at horse shows-- wore these inside fleece line boots and they made my feet colder than the boots alone! Took them out 3 hrs into the night & they were freezing cold! Like standing on frozen aluminum foil! Slightly cushioned, but no substance or worth as insole. I will be requesting a refund, but not holding much hope since they must be cut to fit into shoes
These are great keeping feet warm. I use them in my uninsulated muck boots; they keep me very comfy. Getting some for riding boots next.
