The Finnish army distributed felt boots like these to the troops during the war years and probably a bit after too. Despite the lack of visible stamps these do look army issue boots and the general appearance feels like they're made during the Second World War.
Goodyear welted, with rubber heel pieces, which look wartime stuff. Size is probably 42 (US 9).
Used, abused but the whole package is sort of intact. The other heel could use some repair if you'd like to walk in these. However we would not recommend such historical boots for real use.
