As a 15-year fan and consumer of Kahtoola traction merchandise, my curiosity is piqued when information of enhancements to their designs comes throughout my e mail as a result of every time, I discover it laborious to imagine they may make their spikes choices higher. As soon as once more, nevertheless, they’ve with the Kahtoola Nanospikes ($55), which the model up to date in late 2023.
Kahtoola, primarily based in Flagstaff, Arizona, launched their very first crampon again in 1999, after which translated that analysis into toothy Kahtoola Microspikes, designed for the fast-moving alpine runner and athlete round 2007. Concentrating on the winter street/hardpacked floor runner subsequent, the Kahtoola Nanospikes have been launched in 2015, after which a contented medium possibility within the Kahtoola Exospikes got here available on the market in 2020. The main target of this evaluation is on the brand new, redesigned Nanospikes, particularly designed for laborious, icy roads and surfaces.
Although I’m not a street runner generally, winter requires a sure resourcefulness to get the miles in and maintain the thoughts calm, so dust roads, flatter crushed gravel, and the occasional paved street think about. With our extra widespread trails well-traveled by fats bikes and ft alike, the packed snow quickly turns to ice for lengthy sections, so having low-profile however efficient traction is extremely useful for the simpler, flatter, and quicker operating days.
Thus far this winter, my Nanospikes have been on heavy rotation due to a soaker of an early season storm that dropped two-plus ft of snow in our space. It’s been gradual to soften off, so the low-profile Nanospikes have allowed me to run confidently in street footwear or door-to-trail footwear on the dust roads and clean trails, as they shift from packed snow and ice within the shade to regular dust within the sunny sections. Microspikes and Exospikes could be too toothy and aggressive for the surfaces I’ve been specializing in most not too long ago.
The Kahtoola Nanospikes are available unisex sizes starting from further small beginning at U.S. ladies’s 5 (EU 35) to an additional massive U.S. males’s 13+ (EU 48+). The medium simply suits over my U.S. ladies’s 9.5 (EU 40-41) footwear and weighs 7.4 ounces (210 grams) per pair. They fold in half and match right into a pouch with dimensions of 5.75 inches by 4 inches by 2.25 inches (15 centimeters by 10 centimeters by 6 centimeters). From a sensible perspective, this measurement simply suits into the again pouch of any of my slim 3- to 5-liter hydration packs, or a big pocket of a wind jacket. The brand new product is available in inexperienced or gray, which makes them fast to tell apart when you’ve got an older pair.
Kahtoola Nanospikes Design

The newly redesigned Kahtoola Nanospikes capitalized on every little thing good from the primary design with key enhancements in traction, flexibility, and luxury. I’m a fan of every improve these spikes have obtained. If you happen to favor a video abstract, Kahtoola has an glorious two-minute video with side-by-side comparability of first and second variations.
The primary improve is with the spikes themselves. Ten tungsten carbide spikes are positioned across the perimeter of every traction plate as earlier than, however as a substitute of the outdated convex/pointy design, the spikes are concave. Kahtoola discovered that the concave form will increase the stress and engagement of the spike considerably on ice, whereas resisting abrasion as much as 100 occasions greater than the older and extra frequent metal spike.
Heart plate ridges have been added to the textured forefoot and heel plates to enhance the traction on uneven packed snow and ice, whereas the brand new directional and scooped lugs enhance traction with ascents and descents. I completely agree that the traction offered by the brand new design has improved considerably, which I’ll focus on within the subsequent part.

One other improve is a giant one which addressed a typical concern of the previous iteration. Kahtoola lowered stress factors from the harness across the total shoe by using low-profile rivet connections as a substitute of hyperlinks and by integrating a simplified toe bail over the entrance of the shoe, which retains the shoe from migrating ahead on downhills specifically. The improved flexibility and geometry of the thermoplastic harness permits the Nanospikes to suit snugly with out pulling the entrance of the shoe up which was notably noticeable on the softer uppers of street footwear — as in comparison with path footwear. Gone are the friction factors over the toenails as properly. I can now simply put the spikes on with the improved heel tab whereas standing on one foot with a one-hand pull as soon as I set the toe. Whether or not I’ve street footwear or mild path footwear, my ft are fully snug in these; I don’t have further leg fatigue on the finish of a run.
Kahtoola Nanospikes Use and Traction

I completely agree that the traction offered by the brand new design of the Kahtoola Nanospikes has improved considerably, as I used to be capable of do a head-to-head take a look at with these and my first era Nanospikes on a number of runs, and slippery, icy bike-path canine walks after a latest storm. The brand new concave spikes don’t skitter or slip throughout ice just like the older pointy spikes are likely to, whether or not on lengthy ice segments or on the frozen disorganized footprints on a path.
The traction on hilly, snow-plowed dust roads or well-packed fats bike tracks can also be higher. The ridges on the traction plate catch simply sufficient of the hardpack that even with a street shoe or low-traction path shoe, the ascent and descent is purposeful with much less slippage and fewer calf muscle fatigue.
To be abundantly clear, the Nanospikes are designed to be worn over street or mild path footwear for street runs on icy, plowed, snow-but-hard-packed surfaces. They do positive for brief distances on dry, crushed gravel or smoother dust surfaces between the icy or snowier sections. If I encountered a protracted section of dry pavement, I’d slip them off till the following part required them. For unfastened or deeper snow on entrance nation trails, the Exospikes are excellent; for mountain trails, steeper surfaces, and extra burly terrain, the Microspikes actually shine.

They’re considerably extra snug and versatile, simply as safe, and have improved all-around traction on ice and hardpacked, road-like surfaces. Reap the benefits of upcoming seasonal gross sales and reward them to your self or a pal. These are excellent for walkers, runners, emergency winter automotive kits, and neighborhood post-winter-storm shovel classes.
My first Nanospikes are 4 years outdated and nonetheless going sturdy, which is 4 occasions extra sturdy than rivals’ alternate options in my expertise. I anticipate this new model will likely be simply as lengthy lasting. Nicely achieved, Kahtoola! Sustain the excellent analysis and design.
