If you are standing in snow deep enough to reach to your pant cuffs, who is going to know what you have on your feet? Wear the rubbers and save your shoes. An added benefit is if you have leather soles, or, God forbid, you are wearing a vintage pair of shoes with cleats (like Florsheim Imperials) you are likely to soak the seat of your pants from repeatedly falling on your ass because you will have no grip on slippery ice. Rubber galoshes or overshoes prevent that from happening. Take this as good advice for someone who lives in Canada and knows a thing about coping with winter weather.
By the way, years ago, a friend of mine migrated to Canada in the fall with his pregnant wife. She gave birth in the winter, and he noted a sign meant to discourage the wearing of rubber overshoes into the maternity hospital at every entrance. It read "Thank you for removing your rubbers." At least, he hoped it referred to overshoes.
