Running outside in Ottawa in the winter can have it’s challenges and traction is definitely one of them. Here are some recommendations based on personal experience.
Regular Yaktrax and Yaktrax Pro
Don’t buy them! They don’t work that well on ice and they make running on clear pavement more slippery. The regular ones (without the toe strap) also fall off when running.
These are not too bad on regular ice and snow. They stay on and the small spikes give you better traction on hard ice and dry pavement. The metal coils on the back can break over time.
Ice Trekkers Diamond Grip
These are heavier than Yaktrax Run but they have better grip on hard ice and they are good on dry pavement as well. Make sure you rinse them off after running in the salt because they rust. They last better than Yaktraxs. Mine are 4 or 5 years old. I don't like the clunky feel but on really bad days there are my go to.
Great for trail running and the absolute go to for hikers but you can’t run on pavement with them on. There are other brands around but Kahtoola is everyone's go to.
Running shoes with built in spikes
These work quite well but they are not easy to find and you can’t really use them for all of your running so traction aids are a cheaper option.
Great for trail running but be warned it’s a tough workout and the snow needs to be packed down or it's an even tougher work out.
