When it comes to snowshoeing, the gear is important. If the snowshoes are too big, you'll trip! If they're too small, you'll sink right through the snow, although anything larger than the profile of your foot will spread your weight around. If your winter boots are too heavy, you will tire quickly. If not breathable, you foot will get sweaty. The Steger Mukluks and the bindings that go along with them will affect stride which has a direct impact on how much energy you use.
Steger's are light, they claim half the weight of traditional winter boots. They have different styles to choose from so you should be able to find one that matches your wardrobe.
