I’ve tried three varieties (weights per pair in grams, large size):
Yaktrax, 92g
Walmart Safety Treads, 221g
SureFoot Get-A-Grip Advanced Cleats with Studs, 302g
The last has replaceable studs. I believe I bought them at BaseGear.com. The Walmart Safety Treads have “studs” on the front of the boot only. The first two pop off fairly easily as you hike. I used various methods last winter to keep from loosing them. The Walmart item is cheap, about $4 for a pair.
I use these for hiking in the desert during the winter when there isn’t much snow but ice patches are common. I don’t consider them as alternatives to crampons. If I was hiking on consolidated snow, I would definitely use crampons.
I don’t believe any of these which I’ve tried are ideal. I’ve worn out the Yaktrax type. My son lived in Norway for years. He used some Yaktrax that we sent him and quickly broke them out. He bought some that are like the SureGrip but much lighter synthetic rubber. They also have replaceable studs. I don’t know of a source or the brand name. I like them better than anything I’ve used.
