Bass is best known for their loafer - the Weejun, but they also made other casual boots including ski boots. These are typical ski boots of that time, and from all I can tell from looking in vintage catalogs and online searches, ski boots pretty much remained the same from the 1930s through the 1950s. They were sturdy and very heavy.

I recently found this vintage pair. They are well worn, but really snazzy. And if you don’t ski they could be used for a door stop or as a leathal weapon. They are that heavy.
