I don't use them, but there are a number of stabilizing and ice devices available. Check REI for a good sample:

I run in all conditions including in the snow (it's fun but really hard and tough on your joints if it's packed hard) but I am extra careful. I wear regular running shoes but will probably throw in wool socks if it's cold (less than zero celcius). If it's wet I'll add a plastic bag around my lightest wool socks so my feet don't get cold as fast. But I'll run for a shorter time, not more than an hour, to avoid getting too cold.

You need to be mindful of joint stability and of where you're going to take your next step. I do all I can NOT to step on a clear/black ice patch. Snow is not an issue.

I'm an all-weather runner. Actually I'm mostly a foul-weather runner. When it's nice on the road, I take my road bike!!
