Studded galoshes
This idea has ripened for a long time, but nobody wants to listen to the proposal. About 50 years ago, galoshes were used everywhere. Use studded galoshes in our time during sleet, snowfall, etc. super relevant: I got to the car - took it off, got to the subway - took it off, put it in a bag. I remember that in theaters galoshes were taken in the wardrobe along with clothes. The number of injured will decrease significantly. Of course, the design and material must meet modern fashion needs and harmonize with different types of shoes. It is hardly possible to make such a handicraft homemade. Well, in some factory this offer may become Klondike.
