I'm in my late 60s and have already fallen twice this winter. I hike all winter and hate exercising indoors, so I'm out in all types of weather. I had another brand of ice grippers that are good but just not aggressive enough. These are fabulous! I've tried them out on all types of snow and ice conditions and like the way they perform. I read the reviews about sizing, and measured the bottom of my boots to get the correct size, but I probably should have gone up a size. Boots are 8.5 so got an XS. Could have used a bit more length. The way the straps are set up, my boot hung over in the toes, and the grippers extended past my boot in the heel. But they still work. I like the straps and not having to stretch them over the boots. They stay put, so I'm not back tracking, looking for a lost gripper. Construction is heavy duty. The Stabilicers Maxx have given me the confidence to get back out again, hiking in all types of winter conditions.
