These are some lightweight traction devices that Grivel used to make. I think they would be good for icy patches of trail or walking on slippery snow fields. They weight 6.2 ounces, quite a bit less than microspikes.

I have a pair that has never been used. They come with a nylon carry sleeve.

here is a video of them being used : https://www.youtube.com/watch?v=fwvoIQwSPDs
