I go for a walk nightly regardless of weather so I feel qualified to speak!

I order a dozen yaktrax-like sets from Ali Express. They’re like 2 or 3 dollars so that way I don’t worry about them wearing out or falling off in the snow. Unlike spikes, you don’t feel unsteady or uncomfortable when the sidewalk has a clear section. And they do great in black ice or when suddenly there’s ice under the snow.

I also have severalof thesefor different conditions.

And spikes for when it’s all ice.
