Caulk Boots, ca. 1910. Maine State Museum. Gift of Dale J. Butterworth, 2000.18.615.
Caulk boots had steel spikes set in their leather soles. The spikes helped loggers walk through muddy and snowy conditions. Men would sometimes walk miles from their camp to their worksite through the winter snows.
Spikes on caulk boots also gave loggers secure footing while the men stood on logs during a river drive. These boots still have bark embedded in the spikes.
