Item from Potlatch Lumber Company Photograph Collection. A pair of lumberjack sandals are shown. The description on the back of the photograph reads 'Loggers' sandals worn for noon hour to protect mess hall floors from boot calks.'...
They were worn in the mess hall at lunch to keep the cleats on their boots from messing up the floor.
Reminds me of pattens, except they’re for shoes that already have soles.
