I’m guessing Canada. We get similar temp range in north central and north eastern US.
I’m in the Rocky Mountains, and our range is -15C to 40C (5F to 105F), and I wear my steel toe boots to shovel snow in the winter and garden in the summer. Oh, and I wear the same wool socks in both seasons, which keep my feet warm in the winter and dry in the summer.

Parts of the US (and probably Canada) get to -40.
Many boots now use composite fibres for toe and shank protection simply because of the problems with metal and cold.
