KorkersUltra Ice Cleat - One Size Fits Most - 16 Replaceable Steel Spikes

Easy fitting. Easy putting on or taking off.

I live off grid in the mountains. We recently had a storm drop LOTS of snow followed by a couple days with temps in mid 30's. Lot of melting then night time freezing. After that we dropped into the teens and stayed there. My daily hikes are over sheer ice or 4 to 12” inches frozen snow with a heavy crust. My microspikes were left at our cabin so I bought these Korkers as an experiment.The good part: the traction is (usually) better than expected. Compared with spikes one does not have to “walk with purpose” so much. In return you WILL slip more but so far these slips have been recoverable. You also won't get the buildup of big ice balls you can get with spikes in the wrong combination of fresh wet snow on a cold day, and you won't pick up the occasional pine cone, stick, etc.Regrettably there are many problems.Design flaws: First the “tabs” on top of the toe part make it impossible to attach gaiters to laces or clips on your boots. This is a bad idea made worse by the fact that this tab really does not have the correct vector for pulling the toe half on. I end up using the sides. Putting gaiters on first does not work especially well either. It should be redesigned. Second, the toe part attaches to the heel part via 2 straps about 1/2” wide and maybe 1/8” thick. These are exposed on the bottom of the boot and subject to abrasion from ice and rocks. I'd be surprised if they lasted long.Functional flaws: Someone commented on difficulty getting them on and off. Depends on how much you tighten the straps. Which leads to a major issue. The pics show what has happened to me on the average once a mile – i.e the heel part slips up over the back of the boot. Not sure why. Whatever the cause it's dangerous as you expect to have traction until you don't. I tried tightening the straps to the last hole to see if it would stop this but when I got the things on the boots the round holes in the straps had turned into very long ovals. Seemed WAY too tight and high likelihood of strap tearing thru the hole. I went back to 2nd hole from end. They kept “dislocating”.The spikes fall out. The other morning I was looking down on the trail and was surprised to see one of the orange “cleats” laying there that had apparently fallen out of the device the day before. When I got home I found that one spike had fallen out of the front part on BOTH devices. So in less than 20 miles I've lost two spikes and had the rear portion “dislocate” 15 or 20 times. I managed to find both spikes and “pop” them back in which sounds easier than it is (wet them first).We've continued to have this weird snow/melt/ freeze stuff. Last night we had several inches of snow on top of lots of smooth ice. Went out this morning and came very close to falling a few times in a short distance. While working thru this I had also bought from Amzn a “budget” pair of metal spikes. Went back to the house and swapped these out for metal ones and had no problems at all on the same stretch where I'd nearly fallen with the Korkers.So I will return these. I suspect that they could be OK for very light duty use - city parks, icy sidewalks, keep in your vehicle in case you get stuck etc. For hiking in snow and ice in the mountains spend the money on real microspikes.

I recently received orders to my new duty station in Alaska, and being from Alabama I had no idea what I was in for. Upon arriving to Alaska, I learned quite quickly of the menace "black ice". Every time I went out to smoke, or do anything outside for that matter, it almost always resulted in either tip-toeing my way around, or just straight up ice skating to the smoke shack. After falling seven too many times, I finally decided to get some ice cleats. These things went on in a breeze and worked like a charm! They've kept me firmly planted on walks to the store, but I'd highly recommend not wearing them while walking across tile. Hilarity and embarassment will quickly ensue. Otherwise they're solid ice cleats, fit everything from my work boots, uniform boots, even to my tennis shoes. Highly recommend.

This is a good, lightweight traction device, but the heavy-duty Korkers are really superior (but pretty heavy). I also use Stabilicers Lite and for bare rock seem to work a bit better. I strongly recommend that when using both these Korkers Ultras and the Stabilicers Lite, you use shoelaces to secure the back of the device to the boot by tying over the instep. The heavy-duty Korkers and normal crampons have such an over-the-instep tie. They can come off otherwise, and in relatively deep snow you might not realize it until you have gone some distance. I have also used the Kahtoola MICROspikes Traction System cleats and found them worthless on the type of terrain I hike which has lots of bare rock to clamber over--the chains broke and the metal cleats bent during the first 10-mile hike. I also don't recommend Get-a-grip cleats because the spikes are too small to do a lot of good and get caught in tiny cracks in rock (if you do use them, they also need someway to secure the heel).

These things are great. I was a little hesitant given the somewhat non-aggressive treads and "one-size fits all" claims, but these are the real deal. They provide plenty of traction in ice and packed snow on even somewhat hilly terrain. The way these fit has turned out to be a big perk as well. I've used them with ease on size 11.5 men's trail runners, my wife has used them on women's size 6.5 trail runners and my mom has used them on size 9 women's boots. This flexibility provides a lot of added benefit to these ice cleats that few others have. I haven't used enough to comment on the durability, but they seem well made and am pretty sure the spikes are replaceable.

Works great. Slips on over my shoes and boots in about 30 seconds and can be removed in about 2 seconds. Secure fit and great traction. Not to sound to corny but you kinda feel like a superhero when wearing these on ice. Other people we slipping, falling or walking very slow, but I was able to walk normally and with confidence. I used them in snow and ice but will also try them the next time I have to walk on slippery clay.The size can be adjusted, but they fit both my size 10 shoe and boots without needing adjustment. Secure fit and stayed put with no issues. Unless you walk on a hard surface not covered in snow and ice you really don't know you're wearing them.

I live in Michigan. There's a lot of snow and ice around from Dec - Mar.These cleats aren't bad; they fit snugly over my boots. They offer good traction when new. The downside is that the studs wear down very quickly if you're walking over concrete (I see signs of significant wear after a couple of week's use), and also I've lost a stud due to the grommet popping out from the rubber.

Within a week of receiving these we were able to try these out, when freezing rain & snow hit the Pacific Northwest. They worked very well. They were very easy to put on & for women's size 8-9 snow boots actually needed no adjustment. We were able to safely get to and from the cars, take the garbage out, etc. without slipping around. They also easily went back into their little containers for storage.
