... 1. What do snowshoes do that makes it easier for the person wearing them to travel in deep snow? Snowshoes distribute a person’s weight over the large area of the snowshoes, resulting in less downward pressure on the snow compared to regular shoes. With less downward pressure, the person doesn’t sin ...
