Bought them for work purposes, (professional dog walker) as I needed something that would give grip on slippy paths in winter whilst being durable enough to keep on when there is mo snow or ice cover. Other grips I've used in the past wear out quickly once on dry ground. Only thing I don't like, and this is a flaw I find with many ice grips is that they are prone to sliding out of position on the shoe.

These little lovelies are top notch. Me, and my husband use them year after year up here in Alaska. We have the Microspikes for big deal trail adventures and the nanospikes for the icy daily road walks. Thank you Kahtoola for making quality gear! Now, if only we could get them in kid sizes for the littles. (hint hint) and I was able to change the fact that I mistakenly put in 1 star. They FIVE star people!! All the way.

I used them today for the first time to run outdoors and I was so happy that I could keep going despite the ice! They were great when it comes to traction and they didnt move at all when running. However, as mentioned by other reviews I ended up with very sore toes from the "front" strap and small blisters. I only ran 6km, not sure I would have been able to continue for much longer because of the issue on the toes.

I just bought a pair of NANOspikes, and they give me confidence on sidewalks with mixed snow and ice. I wear them over my New Balance snow boot. HOWEVER, when I went into a supermarket to shop, I discovered they real slip on the stone tile surface and I have to be careful as I was before on ice. What do you say?

Long time user of microspikes, but a first time user of nanospikes. Got a pair for Christmas. Due to a mild winter so far here in Montana, the trails I run have been extremely icy from constant thawing and refreezing, but the nanospikes have been amazing. Zero slips at all, even in the worst of trail conditions, and up and down grades. The first time I used them, I too noticed significant pain and pressure on top of the toes, like some others have experienced. A half-mile in to my first run I had to stop, and I noticed the strap that says "front" was twisted slightly on both feet. By simply straightening it so it laid flat against the top of the toe area like it's supposed to, the pain and pressure went away. The strap will stay down once flattened, it's not a recurring problem within a run. I'm sure those who have experienced this problem checked all that, but it's just something to be aware of. I love them! Lighter than the microspikes and perfect for lesser grade runs.

I love them because they provide excellent traction on even the most icy conditions when I run and they stay secure and never fall off. But I too have found that I get discomfort in the big toe area where the "front" tab is located and the metal link connects. This is regrettable because they are otherwise terrific. I also experience some pain in the tarsal bones due to the pressure exerted by the device after longer runs of 10K +. I am currently wearing Mizuno Wave Rider running shoes and yes they have a soft upper like most running shoes do. I should note this happens only on my right foot. The other side is fine. Maybe there is an insert I could slip under the toe area to distribute the pressure more evenly or perhaps you may have a suggestion.

This company make a VERY GOOD product, Nanospikes. After my dog demolished one of my pair and I couldn't get another replacement pair from Calgary (out of season), I CALLED THE COMPANY. Oh, I am not just a satisfied customer, It was an INCREDIBLE phone call and to say that I got satisfaction is an understatement. EXCEPTIONAL CUSTOMER SERVICE. Thankyou to Kahtoola, I will buy another set IF and when these wear out. https://kahtoola.com/product/nanospikes/

Kahtoola NANOspikes I wholeheartedly recommend NANOspikes! I have found NANOspikes to be very effective for running on both ice/snow and mud. A couple days ago, I did a trail run where the conditions were more mud than ice. I applied the NANOspikes to my Merrill All Out Peak trail shoes before starting out. I was very impressed with the performance of the NANOspikes. Where other runners (who were probably not even wearing trail shoes) frequently slipped in the mud, I was able to maintain traction throughout. NANOspikes provided me with increased confidence when running under conditions what would otherwise have produced anxiety. There were no issues with clogging (balling). I did notice that after a while, the NANOspikes shifted slightly on my shoes, but they were never close to becoming detached. I attributed the shifting to the constant direction changes as I was running. That said, I may attach straps to the NANOspikes for my next run. If for no other reason than to prevent loss of the device if it should become detached from the shoe while running. I have also had the opportunity to test NANOspikes on my Lowa Camino GTX hiking boots while hiking in Harriman Park in New York. Once again, I was very impressed with the NANOspikes’ performance. There was a snow cover of a few inches, with a thin glaze of ice covering powder snow. On much of my hike, the trails were previously broken by other hikers, so I was walking on partially packed powder. The snow was dry, so I did not have a problem with balling. There were a few spots where the snow was wetter, but there was no balling even in those spots. If you know Harriman Park, you know that there are lots of places where you must step up onto rock slabs, which are not flat, but angled steeply. When these rocks become icy, they are extremely hazardous, and can be impossible to negotiate. Often, the hiker must walk off the trail, into the brush just to avoid these steps on the icy rock. On a previous hike, wearing an old pair of instep crampons, I found my footing on these icy steps to be precarious at best. On the other hand, with the NANOspikes, I was able to simply step up onto the icy rock as though it weren’t ice covered at all. This gave me confidence, making my hike much more enjoyable. One note: I always hike with TWO poles, not just one. This can make all the difference when negotiating slippery slopes. While the poles cannot stop a fall once it has started (you need something stronger, like an ice axe to do that), they will help you stabilize yourself to prevent the fall in the first place! Also note: Before using the NANOspikes (size Large) on my hiking boots (U.S. size 11), I was not sure they would stretch to fit the larger shoe profile. My concerns were allayed when I tested them on the boots before setting out for my hike. The rubber components of the NANOspikes stretches (and recovers) well. I was very pleased to find they fit my hiking boots, since my only other option (other than an old pair of instep crampons, which aren’t very effective) is my Koflach mountaineering boots with full 12 point crampons. For the conditions I hiked in Harriman, the crampons would have been extreme overkill, and most likely would not have worked as well as the NANOspikes did (the ice was far too thin for crampons to get a good bite).

Living in NE Wisconsin, my options for running are the treadmill or deal with snow and ice. I have put about 30 miles on my first pair of Nanospikes after getting a good recommendation from my running partner who also owns a pair. I do love how light they are and I have been very happy with the added traction. They’re not big enough that my stride changes or are very noticeable on shorter runs. I have tried them on several shoes including my go to winter shoes, Saucony Peregrine 7 Ice, and a pair of Brooks Adrenaline 18s. On a size 11.5, I have been using the Large Size. I’ve had no issues with toe pinch as other reviewers have stated. My only complaint is that the front traction area slides inward towards my big toes and gets cockeyed on the bottom of my shoe. This requires me to stop every mile or two and readjust. Not a terrible experience but it can be pretty annoying, which is why I lowered my review. It’s better than sliding or falling on ice or having to stick to the treadmill so I guess I’ll tough it out.
