Icy roads and sidewalks are the Winter runner's [1] nemesis. Slick surfaces translate into slips and falls, which can lead to injuries, so you need sneakers with added traction for slippery situations. Runner's World [2] has created a cool and cheap solution: Screw Shoes. The concept is similar to studded tires for your car; the screws create little ice picks on the bottom of your running shoes. Check out the January issue of the mag, flip to page 50, and marathoner Matt Carpenter will explain how you can transform your favorite trail runners into studded sneakers in minutes with a few sheet metal screws.

Would any of you ever try making these studded sneaks?
