If you'd like to run outside in the winter, but you worry about slipping on sliding on the snow and ice, there are still ways you can get outside and be safe. The usual cold weather running safety rules apply, but you also need to take some additional steps so you keep your feet warm and avoid slipping and falling.
Use ice grippers.
Yaktrax Ice Grippers offer traction and confidence for winter running. They slip right over your running shoes, without adding any weight. The spikeless coils provide a solid, predictable grip so you don't slip or slide.
Mix things up and try a different type of workout with a pair of snowshoes. If you can run, you can snowshoe. Many places that rent skiis also rent snowshoes, so you can try them out and see if you like snowshoeing before making an investment.
Put screws on your running shoes for traction.
Running & Jogging Forum member Allen has a great solution for running on the snow or ice. He secures hex-head screws on the soles of a pair of running shoes. Check out his YouTube video on how to make your own ice/snow running shoes.

Use two pairs of socks.
If it's really cold, you may need to wear two pairs of socks –- one thinner (synthetic material) pair closest to your feet and a thicker (wool) pair over them. The one caveat for this strategy is that you have to be careful that your running shoes still fit properly with the extra layer. You may want to purchase another pair of running shoes that are a 1/2 size bigger than regular running shoes, so you have some extra room. To help prevent your feet from sweating too much, spray antiperspirant on them before you put your socks on.Winter Running Socks
