Product Description

Spike Design

Made from tungsten carbide, each spike is extremely wear-resistant for use on pavement without affecting foot strike, and is held in place with a lightweight aluminum anchor, while a surrounding TPU cleat provides added traction and shock absorption.

Reinforced Eyelets

Reinforced using durable TPU inserts to ensure longevity, each patented eyelet allows the elastomer bands to be lighter and stronger, preventing tearing along the harness and at connection points.

Traction Plates

Upward-facing traction ensures NANOspikes® stay in place against footwear.

Dual Compound

Using TPU construction, a softer compound provides wear-resistance, flexibility and aides in snow release, while a harder compound near the spikes disperses force against the shoe’s sole.

Toe Bale

Highly flexible with recessed connection points, the toe bale secures the foot’s position at the front of the shoe for added comfort, preventing the toe from pushing through the front of the elastomer harness.

Raised Heal Tab

Allows for easy pull-back and removal.

Elastomer Harness

Low-profile, extremely durable and ergonomically shaped, the elastomer bands are constructed from TPE for a secure fit and remain stretchy down to -30°F.

    Surprised I am the first one to review these. Nanospikes work great. I am a trail runner and hiker in Colorado and the Nanos have not let me down (no pun intended), yet. They are very easy to put on and take off. I don’t feel like I’m running on clunky spikes or tearing up the trails in these. Plus they are $20 less than Micros. Will definitely buy again.

    These things are fantastic for walking around any snow/ice. I use them for hiking on low-slope/flat areas, walking the dog, shoveling the driveway, walking almost anywhere that may be icy or hard packed snow. They’ve never let me down. My company uses them and issues them for Personal Protective Equipment to help keep our employees from falling at work (construction).

    These work very well for traction on ice when trail running. My problem is, my toes start to hurt after about 3 miles. The top of the device presses uncomfortably on the tops of my toes and I end up with sore toes.

      Hi Cynthia,

      Thanks for your review. We appreciate the feedback and wanted to reach out about the issue you’re having with our NANOspikes® and the pressure they’re putting on your toes.

      While they do work with a wide variety of shoes, through testing our NANOspikes® with a number of different shoe brands and styles, we’ve found that the round connection points of the toe bale labeled “FRONT” can sometimes rub through shoes with a softer mesh top or that have a narrow toe box. Depending on your shoe style and foot size, it could also be as simple as going up a size in the NANOspikes®. Either way, we’d love to speak with you about the issue and help resolve the situation however possible. Please feel free to reach us directly at (866) 330-8030.

    These are fantastic. I use these for running on icy roads and sidewalks and they are excellent. I am very happy that I did not go with a cheap knockoff but bought these. They are worth every penny. Love these!!!

    Ran 9 miles in these today on the road. (Borrowed my wife’s.). We had three inches of snow over ice. I loved them and just bought a pair for myself. They stayed on and added a little weight but not enough to be concerned. I am a believer!

    These work really well to grip the snow and ice compared to other brands of spikes I have tried. They fit almost seamlessly so it feels like you are wearing shoes with built-in spikes, but they provide the flexibility of using them on different pairs of shoes! Sadly, like a previous reviewer said, I too, get sore toes (from the strap labeled FRONT), though I have tried them with several pairs of shoes on several runs.

    I run 20+ miles a week. I put these on my Altra Timp trail shoes which are well reimforced shoes for trail running. These are not made for running shoes with a mesh top. The rubber straps press in on your toes and you will give up running after a few paces and go home.

      Hi Dwight. Andrew with Kahtoola here. I’m sorry to hear that this is your experience. While our NANOspikes are designed for use with running shoes that are constructed with mesh tops, we’ve found that sometimes the straps in question can rub against the toes based on a person’s foot and shoe profile, but not often. Personally, I use these with my the Altra Timp IQ, which are very similar to the original Timp, and haven’t had any issues. Overall, we’ve found the NANOspikes work well with Altras. As you can imagine, we don’t want this to be the experience our customers have, and I’d like to learn more and hopefully find a way to resolve this issue if you wouldn’t mind emailing me at Thanks!

    These are the best!! Winter running in northern Wisconsin can be a challenge with the snow and icy conditions. I’ve used my Nanospikes now in multiple conditions without any problems and feel so much more confident. They transition well from ice and packed snow to pavement on partially cleared roads and allow me to run without obsessing about hitting a path of black ice. Highly recommended!

    These work so well-wish I would of purchased them sooner! Ran 10+ miles today on hard packed snow/ice and never slipped once. As with other reviewers on here, I also noticed how the front seems to press fairly hard into the top of your shoes. I too used them on Altra Timps and stopped a couple of times to try and adjust how they were sitting on my toes. It wasn’t bad enough to make me stop running but I may go back to where I purchased them and see if they will let me try a different size. Overall I will still highly recommend these!

    I love these NANOspikes so much I’ve bought two sizes for myself and a pair for my son and tell everyone about them. I generally wear a size 7.5 women’s shoe, which is right on the border between XS and S in the NANOspikes. I have an XS to go with my “barefoot” style of Merrell Trail Gloves and just bought an S to go with my hiking boots and larger athletic shoes. I read tons of reviews on both outdoor and running websites before deciding on these spikes. Still, until I could actually use them myself, I was skeptical about my first step on ice. I am extremely pleased to hear the extra “crunch” of the spikes and to feel secure as I walk and run. So yes, if you live in an area with ice, these are the spikes to buy.
