One simple way to "upgrade" from a road shoe is to try a trail running shoe. Trail running shoes are lightweight and can sometimes be a little bit warmer than road shoes. Some offer a degree of water resistance that is helpful in the snow. Trail shoes also boast some added traction through a more aggressive tread pattern. And, because they tend to be more stable, trail shoes can work well when you have to run over snow. Unfortunately, trail shoes won???t help you much on ice. And depending on how aggressive the tread pattern, they may feel clunky running over dry pavement.
Sevendaughters the above is taken directly from the article you posted. I think if I read correctly it says wear trail shoes for snow. And as the op has asked how we are going to run in snow then I am defo going to try my trail shoes in the morning.
