There are many opinions about heat loss in footwear, and many claims from manufacturers about the amazing insulation in their boots.
Has anyone measured or imaged  this?
I would love to see some thermal imaging of feet inside boots on a cold day.
Any measurements of how much heat you lose through the sole? Do Crampons make a difference?
Lot’s of questions.
If anyone has any links to studies or casual measurements, I’d love to see them.
Thank you
