mukluk

Her parkee, made of Caribou, it is a lovely fit, / And she's all right from muck-a-luck unto her dainty mit. / This lovely Klooch is fond of Hooch, and makes it very well.

… the Canadians’ [soldiers’] mukluks and sleeping bags were superior to anything in use. the mukluk, a rubber-soled boot with a calf-high outer nylon cover, has a thick woollen inner boot that keeps feet warm in the coldest of weather.
