Most bad days on the ice start with a slip, not a crack. Clear black ice with no snow on it is as slick as a rink, and a thin skim of snow over wet ice is worse because it looks grippy. You are usually carrying a rod, a bucket and an auger, so a fall lands on your hip or the back of your head with nothing to catch it. A pair of cleats on your boots fixes most of that, and it is one of the cheapest things on the ice gear list.
Buy for the ice you walk on and the boots you wear. Steel spikes and carbide studs bite into hard, bare ice, which is most of what a lake gives you in midwinter. Coil cleats like the Yaktrax Walk and Pro are made for packed snow and icy sidewalks and grip less on glare ice. Big insulated pac boots need an XL size or a strap-on design like the STABILicers Maxx 2. If you drive a truck or ATV out, a heel or mid-sole cleat leaves the front of your sole free for the pedals.
Tom has not tested these cleats on the ice. The picks are ranked from what each Amazon listing states, Amazon buyer ratings and AI-assisted research, and no brand paid to be here. The Yaktrax Walk has the deepest buyer history, 4.4 stars from 27,224 Amazon ratings, but it is a sidewalk cleat first. The K1 Heel-Stop has only 121 ratings, so treat its 4.3 stars as early evidence. If you are still putting together the rest of your ice kit, the beginner ice fishing gear guide is linked just below.
