I have been using that anti slip tape method for a few months now. So far it is working great. It does fine in wet weather. It protects the sole and improves traction on smooth floors and carpet. I have only walked on ice once with the tape in place. I was careful and did not slip, but it is too soon to tell how well it works for winter wear. I use grey tape, rather than black. I think it looks better. Much cheaper than rubber sole protectors, and does not make the shoe hot. I find the sole protectors provide so much insulation that they get make the shoes uncomfortable.
