I have size 13 pack boots and the extra large fit great. As far as traction they grab the ice like no other cleats.I also like the easy on and off.

Every winter, Ive fallen a few times on ice while shoveling snow. These micro spikes are like a (Meteroid) power-up that lets me safely walk on ice when I need to. It even works on a hilly road with ice. Notes: 1. Its really easy to slip on. I am not afraid of these snapping spikes into my eyes like my old set of $15 ice spikes. 2. I have a mens 10.5 size Timberland boots and the Large size micro spikes was perfect. 3. The micro spikes are not really intended for hard surfaces like asphalt and concrete. I do use the micro spiked on those surfaces when there is ice.

These are THE BEST option for affordable microspikes ever! I got them for hiking in the Rocky Mountains last weekend. The entire parks trails were just sheets of ice and with these spikes, we were hiking on them so easily, we almost forgot that we were walking on ice. Funnily enough, all the people around us who were walking fine had these exact same spikes on. Everybody else was struggling for grip. I got the Small size for my size 8 Merell Moab shoes and they fit fine. These microspikes are essential for winter hiking. Highly highly recommended!

The incline in Manitou Springs is icy this time of year...couldnt live without them. Stable and safe in any icy conditions.

Awesome for ice fishing or moderate hiking on ice. Probably overkill for walking on the street. They run maybe a little smaller than expected; I wear size 12 boots and bought large. They were too small, but I bought XL next and they fit great.

1-21-18, these are so much better than Yaktrax. The spikes make the difference. I wear a 10 Keen hiking boot and ordered the red medium. Work well on the ice as you can see in the picture. The wrap is great and they dont move around on the shoe.

Low profile spikes for mildly icy conditions where crampons would not be helpful. Perfect for winter in the American Southwest.

My wife and I have been wearing the various iterations of MicrosSpikes since 2009. We live in MN and put about 4-5 miles per day on icy winter trails. I have tried other brands and none have compared to the fit, traction and toughness of these spikes. If you find yourself walking like an ice-skating polar bear - give these a try you will be blown away. They are great on ice and also in snow depths where you would start considering snow shoes. They are also very good in the spring when you have a mix of icy patches and frozen ground. My wife is 5.6 and 120 and has never broken a pair. Im 6.6 and 260 (maybe a little more after Christmas) and i have broken the chain links on a couple of them. Frankly at my size, the amount of ice we cover and the frequency of our hikes, Im surprised they last as long as they do. Kahtoola and The Shuttered Image have been very responsive with replacements and recommendations. I would remove them after each use to allow the rubber to remain tight and to allow your boots to breath - you may see a little condensation where the rubber covers the boot. Long story short- I wouldnt hike in the winter without these spikes.

I hike a lot in the Pacific Northwest and we get a lot of spring melts from the mountains. These are amazing! Grip the snow and ice. I prefer the black over red, just for blending with my gear.

This order was for two extra pair of these cleats. These are absolutely the best cleats I have found. We live in Anchorage, Alaska and I use them to walk up a trail that starts at out back door and runs up a mountain for about 1-1/2 miles and has a vertical climb of about 750 feet. It is icy all winter and pretty dangerous without good traction. These cleats are the best.
