That's cool but I'm not sure if it's needed. I used to ride my 10 speed year round with no problems. But we had the roads and side walks plowed. And nowadays the bikes have pretty big knobbies, so I don't know.
Here's one for you. I took a screw gun and screwed a bunch of screws into the soles of my boots then cut the ends off with a pair of pliers so I could get better traction walking on ice. That worked okay but when I had to walk in malls and such on tiled floors, it was pretty slippery. Meh, sometimes you just can't win.
