Feet will get cold without a floor. "Suitcase" style helps or foot warmers. Insulation fabric does help, it will still be -20 at your feet and 200 at the ceiling. Maybe the pop up style with plywood cut out for holes? Better yet two pieces of ply wood with insulation in between. Or maybe your kids don't sit still like mine and the feet will stay warm. Sometimes just out of the wind is all you need![/QUOTE

Remember a friend taking along some thin plywood or sometimes a chunk of carpet to set his feet on. He claimed it helps.
