New cleats worked fine on black ice

I wore my new cleats during the run today. Except for the 0.6 mile break-in of the cleats, this was my first run with them. I had no problems with the wet path. There were patches of ice here and there, and I stopped and moved my foot across the ice to see if the spikes kept my foot from slipping (they did). When I got back to my car, the parking lot was in the shade of a hill, and the water on the lot had frozen. I had no problems walking on that black ice.
