There is usually ice on sideways and parking lots in my area most of the Winter. When going outside, I use a special pair of boots with icers installed. Walking about five km every morning, I have never slipped, when wearing this type of studded device.
Note: There are about 30,000 emergency hospital visits each year in Canada due to people falling, mostly on icy streets. Most people never wear icers. You figure.
