Traditional snowshoes have a hardwood frame with rawhide lacings. Some modern snowshoes are similar, but most are made of light metal while others are a single piece of plastic attached to the foot to spread the weight. In addition to distributing the weight, snowshoes are generally raised at the toe for maneuverability. They must not accumulate snow, hence the latticework, and require bindings to attach them to the feet. While today they are mainly used for recreational purposes, primarily by hikers and runners who like to continue their hobby in wintertime, in the past they were essential tools for fur traders, trappers and anyone whose life or living depended on the ability to get around in areas of deep and frequent snowfall. Even today, snowshoes are necessary equipment for forest rangers and others who must be able to get around areas inaccessible to motorized vehicles when the snow is deep.
