I feel like I am searching for a unicorn here. I am tired of having cold feet during winter so I am looking for a new pair of boots. I am specifically looking for 400g of insulation but that in itself is pretty rare. On top of that, I would prefer the boots have no real leather. I’ve found nothing so far! Any ideas?
Here’s an example of a boot with 400g of insulation but as you can see it uses leather.
