often seen in the street without a hat

Pretty good - they were never hugely grippy to begin with, but they're made of a resiny material and the bottom is still pretty rough not smooth. I tried to get a better picture but it doesn't work! Basically, I would not choose these boots to do fun slippy slides on a polished floor because there's be too much resistance, but I wouldn't choose them to wear on an icy street because they wouldn't necessarily keep me upright.
