I wore ice-gripping tread covers on my boots into the subway. It was like wearing tap dancing shoes with the embedded metal studs, noisy but with a rhythm. However, the cleats slipped this way and that, turning the stone floors into sheets of slippery ice. Clinging to railings on the stairs got me to the station platform. On the train I pulled them off the soles of my boots. Other passengers, unsure what I was doing, trying not to appear to be looking, watched them flop, beached fish from a hole in a frozen lake as I threw them wet and salty with slush onto newspaper.
