Focused on the Road Ahead

Keep your urban adventures going all winter long with high-performance traction designed specifically for hard, slippery surfaces. Ten ultra-tough tungsten-carbide spikes underfoot shrug off high-mileage adventures on abrasive surfaces like asphalt and concrete, while a low profile design means you won’t have to adjust your stride while running or walking. For increased comfort, the spikes are integrated into flexible plates that disperse impact forces on the foot, so you can stay out longer and go farther.

      First of all, nanospikes are great. I use them for both icy run commutes to work in Boston (before the sidewalks are treated) and winter trail running. I don't notice the on my feet and I am able to run normally w/o stopping over icy patches etc. because the traction is great. They also help prevent the risk of injury since I am not constantly changing my running form to avoid slipping. Secondly, I will forever be kahtoola loyal due to their excellent costumer service. I bought my nanospikes about 2 years ago and was upset when my dog chewed through one of them. I emailed them asking if I could pay for a repair (given that obviously a warranty doesn't cover for pets being jerks!) and they said they could send me an old demo that they had lying around in the office. Not 4 days later, my new-to-me (but used) replacement nano-spike arrived. I could not be more impressed. Great company with great products and great customer service.

      I bought a pair of these in Iceland while I was on holiday there a couple of years ago. Now. back in the UK, I haven't had the chance to wear them until yesterday - we finally have big snow and I can go run my favourite trail in the snow and ice. The NANOspikes did not disappoint. The first mile is on pavement and was solid ice. I was able to run normally with no slipping, even on steep inclines up and down. When I got to the trail parts and it was more snowy, still no slips. The spikes felt light, and comfortable. I am a happy customer. I would be tempted to try the ExoSpikes for trail use (I don't think they had them a couple of years ago when i bought mine), but the NANOspikes also do a great job.

      I have used my Nano Spikes now for two years on our Colorado trails. Love the traction and confidence they give on ice. I have had the same problem as other reviewers that the front strap digs into my toes. I've adjusted and looked at my wife's pair (who does not have this problem) to no avail. My solution has been to take them off and wear them backwards. No more toe problems but still great traction. I would love to give them more stars but my toes won't allow it.

      Get The Spikes! I don’t review products, on the internet, ever. But these are sooo good, I really want other people to know about them and use them. Is six stars an option? I live in the Minneapolis area, and for years I have had to curtail running in winter because I can’t find a good, safe place to run. And I HATE treadmills. There is a plowed trail near my house, but it often goes to ice from just a bit of melting. Then, wham, the cold comes. With our consistently cold temps, it stays as ice for weeks. If it snows, they clear it, but the ice remains. The Nanospikes are awesome. I run with confidence - there is no “skittering”. They are lightweight and don’t affect my stride. Yes, there is a touch of pressure across the top of the toes - only a touch - NOT enough to blister - and that toe strap is there to hold the spikes on securely. I stretch that specific strap after I put the spikes on and that helps. I NEVER notice the pressure when actually running, only when I just put them on. I saw the toe pressure comments in the reviews and almost didn’t buy these. Don’t be put off - try them! By the way, they also fit over my hiking boots, so I am now snowblowing my driveway in these, due to an unfortunate ice layer that is fused to the asphalt and which will be with us for another two months. Again, as I maneuver the snowblower, I don’t even realize I have these on - I just have great traction. I find myself telling other runners on the icy trail, “get these spikes”. I wish I knew about them years ago. Consider me a true convert!

      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.
