I found a pair of these no longer produced buckled boots ("Loungers") on ebay, and couldn't resist them.

When I first slipped them on they felt awfully small, turned out the previous owner had worn them with an insole, and after taking that out they fit perfect.
Actually they are so comfortable that I've worn them quite a couple of times already, while there is no snow or real cold weather yet.
They might not be the "prettiest" shoes ever, the comfort really makes up for that, comfort-wise they are literally like houseshoes/slippers for the outdoors.
