A thick felt boot liner to fill your boots in a really cold weather. Czech army surplus. These are practically just as good as modern felt liners, but a lot cheaper. The only downside? We probably can't get more.

Made from some kind of woolly-poly blend, no idea what but it's warm. Soles made from synthetic leather or something, of course with felt on the top against your feet.

Sized according to the foot length in millimeters (round upwards). For those in a hurry, there's the comparable EU/French size in the brackets. These run a bit narrow when new, but they'll quickly form to your feet.

Condition

Unissued military surplus, perfect condition, there might be some storage wear of course.
