Finally gave the "traction aids" for running on ice and snow a whirl while visiting my mom in cottage country over the holidays. It was minus 20, likely colder than that with the windchill, so I bundled up and gave it a go!
I will say though that since I have been home, I took the shoes with the traction slip-ons on for a run on our city sidewalks and through my local park. I got about 10 min out of the park before I realized one of the aids had slipped off! I made tracks back to retrieve it and had to sit on my duff in the snow to put it back on my shoe! I really didn't notice it missing at first until I looked down!
Placebo affect? For me, I could still feel the other shoe digging in.
All in all I really think they are worth the money. I know you can get a cheaper version at Giant Tiger, not sure if they work as well.
Even just for my own piece of mind, I seem to push myself faster, knowing I won't hit the dirt, er ice!
Love my traction aids and my RunKeeper app!
