On Cloudboom Strike LS

[@LashanR]

Very cool tech, though for $330 I was expecting On to scan my foot and print the upper perfectly true to size (I thought that was the whole point of a printed shoe 😂)

[@LFKY13]

My question is: The new Alphafly’s cost $285-$300 so why isn’t Nike getting the same treatment of skepticism and demands as On? I believe you’re paying for a new laceless technology that is almost completely carbon neutral, sustainable and made in house. Nike is making their products in china/vietnam with god knows what working conditions with 0 sustainability in mind other than maybe the box it comes in.

[@matthewpena4169]

The tech is definitely adaptable to personalized fits in the future assuming the lasts can be easily printed. also, if the smooth interior is bothersome, the lasts could be textured, and the sprayed-on material will take up that texture.

[@oiagreek]

@@LFKY13but Nike doesn’t advertise their production tech like On does. If they are making the tech the highlight of it, people would reasonably expect that as part of the shoe experience and are paying for it

[@nicholas5396]

Give it a few years. That very well could come to a shoe store near you at some point. Or even better a cell phone app and socks with dots plotted on them. Custome order on phone, shows up two weeks later in the mail. No more questions about fits true to size or not 😮

[@nicholas5396]

What if in a few years a foot scanner comes to a shoe store near you at some point. Or even better a cell phone app and socks with dots plotted on them. Custom order on phone, shows up two weeks later in the mail. No more questions about fits true to size or not 😮

[@calebashburn8943]

Ooh, looking forward to a 100 mile review video on this one now! Super cool video!

[@LFKY13]

For anybody concerned about the longevity even after Mike’s review. I want you guys to know that I attended a private event at the On NYC Labs and got to talk to Johannes (the creator of LightSpray) for a good amount of time and he’s so confident about the material that his next project is to put this in a more accesible daily trainer. It seems LightSpray is here to stay for the long run.

[@styx15]

Usually how shoe tech goes. Starts in the top stuff and works its way down, just like how a bunch of daily trainers have PEBA now.

[@michaeltanel3815]

​@@styx15Good point. Frankly depending on the way it's used, this type of innovation might actually make me interested in trying an On shoe.

[@DZero_Aperture]

Agree with some of the other comments. For $330 I would expect them to scan my foot and make the upper match me 1:1 which would be amazing. Glad there is growing competition from On though, even if I don't prefer their shoes.

[@kofuzi]

I was thinking about it quite on my run after publishing this video, and I'm thinking that, depending on how marketing costs get allocated to this shoe, how R&D costs get allocated, and the relative small number of units that they will likely be making, this shoe probably costs On more than $330 to produce. If they made like 10x (or some other hypothetical amount) the shoes at the same price, maybe they'd make profit. If they made 15x, then maybe the price could come down (which isn't typically a priority for On) or there could be more customization. I did ask about customization though and how it would intersect with the rules against bespoke or custom shoes for elite athletes at World Athletics events. The On rep I was speaking with didn't have an answer for me at the time.

[@benjaminsantiagosstuff]

I subscribe to the cyclon shoes and it would be so cool if you could scan your foot and then subscribe to the LS when you have a race.

[@TBasianeyes]

@@kofuzi believe it or not, they are surely making a profit on this shoe. because we already know that a flagship shoe can be sold for over 450$. it's really hard to price in the r&d because that usually has a different amortization schedule.

[@Prakash.Uthappa]

Amazing shoe! Weight and other parameters aside, this is a quantum leap in shoe tech. Kudos to On, for being brave to go down this path, unlike the other manufacturers just playing it safe.

[@JohnBirtchetSharpe]

We are so lucky being around at this time of innovation ❤

[@FrancescaBuscicchio]

As a shoes nerd, I just love this brave idea of shoe and I’m impressed by the technology. I think that On is doing an amazing job 😄

[@Feanaro5503]

I can’t comprehend the courage required to wear socks that don’t go up high enough to prevent the shoe touching raw skin 😅

[@adrianbjones]

Triathletes go no socks at all and it's no problem for most shoes.

[@LFKY13]

The material is very smooth on the inside. It’s not the same surface as the outside.

[@kofuzi]

it could have gone very poorly. thankfully, it worked out just fine

[@chrissellers4519]

I had a lot of early ON shoes because they were fun and quirky, I moved away from them because 'normal' shoes were just better. Seems ON have figured this out too.

[@itaymeiri5745]

The future I'm excited about: Going to the store. Getting your feet scanned. See what is the best fit of lets say 10 predetermined lasts. have the machine spray that last in a few minutes. I just don't think the economics of this machine can let that happen :(

[@LFKY13]

@@itaymeiri5745 not only the economics but the lack of engineers that are educated about this machine’s hardware/software plays a huge role as well. Johannes had mentioned he didn’t even want to be at NYC but that he needed to be there because only 2-3 people at On know how to troubleshoot and work around the machine in case of a failure.

[@kofuzi]

I can't remember if it was Drew, Bromka, or someone else that I was with in New York when we were watching the machine, but that person reminded me that localized shoe production was the promise with Adidas 3D printed shoes, too. And I feel like the industry would have to just change so much, and shoe stores would have to continually invest so much, that I'm skeptical that we are anywhere close to any brand having any machine that would be able to custom produce a shoe based on a customer's actual foot in real time.

[@michaeltanel3815]

​@@kofuziAlso remember that the promise of 3D printing in general was similar. Everyone could print everything they'd ever need. Where are 3D printers now? I agree with you, probably not feasible at a store level.

[@chocolatechow7697]

as always , much appreciated for explaining the line up and special thanks for letting me know at 16:20 🤓

[@kofuzi]

I got you

[@mav3ric100]

Don't get me wrong the upper and the process they're using to make it looks cool but as soon as I saw the shoe in the thumbnail...what brought me here was what the middle was going to be like. I don't buy shoes for the upper, but rather the missile experience. The upper is a nice icing and as long as its got a good lockdown, I couldn't careless. What I care about is what I'm going to be landing on with each strikes/steps and will it be as wonderful as the beautiful design of the shoe.

[@kofuzi]

I'm pretty much the same. An upper can ruin a shoe, but it usually isn't a selling feature for me. And just like I thought the lightness of the foam in the Evo 1 was it's killer feature, I think the lightness of the LS (which is possible because of this upper) is really quite impressive.

[@TommyEnroth]

Love your content! These kind of information videos are very helpful.

[@kofuzi]

happy to hear that!

[@LashanR]

Been waiting for this!

[@kofuzi]

thanks for your patience!

[@Johnnydodgin]

Would love to see a ‘Kofuzi World Tour’ series featuring an episode with a visit to the ON offices in Switzerland.. 👌

[@kofuzi]

fun fact: when I was in Zurich for the Mondo vs Warholm race, one of the group activities was a walking tour. And the tour company was going to take us to go see the On campus, but they didn't realize that everyone was here on a media trip with Puma. so that part of the tour was removed from the itinerary, and the tour company did a very good job of finding other last minute places for us to go to fill up the tour schedule.

[@cohan.forcer]

Great video, gave me a lot of answers. Also loved "On explained" part!

[@kofuzi]

Glad you enjoyed it!

[@LukeTalbot3]

What a fascinating shoe, I love lacing up my shoes and all, but the efficiency in not having to tie and untie your shoes 👀

[@kofuzi]

and you won't have to worry about them getting untied, which the Cloudboom Echo 3 was particularly problematic for me

[@ScheKitoff]

Their loops should be on the mid for compression feels during transition- they can keep the stack height and firm foam. I know they have engineers for that but it seems like theyve considered bounce for walking more.

[@iwubgygan8404]

Reminds me of Adidas City Socks shoes and those were my one of my favorite comfy lifestyle shoes :o

[@Kyujin_Jang]

Looking forward to your review in the new Asics Novablast 5❤

[@sean6222]

Concerned about longevity. Also the price is insanely inflated. It's not my job to pay for ONs expensive equipment 😅

[@ticodatte]

very cool shoes and video, but my question is adios pro 3 still worth buying right now?? adios pro 4 is so near....

[@ponderingfox]

Hey! Will there be a buyer's guide coming out in the next couple weeks before Thanksgiving Shopping? Also, I just noticed you cracked 200k. Congratulations!

[@mitchellbjerke5547]

Fordy runs called Adios pro 3 the best supertrainer for 2025. Was surprised and now potentially interested.

[@AdrianNiveau]

Interesting shoe and great direction ON is taking. Nevertheless I got hard times liking the cloudeclipse and cloudsurfer next I got. They both are cushioned but still firmer. The sizing is so different, cloudeclipse runs wide and long. The speedboard is annoying and outsole is collecting stones and dirt a lot.

[@kofuzi]

I can read a very little Korean. but thank you for watching, even if I'm talking a bit faster than normal.

[@ShoeFinderMan]

@kofuzi you shoud do a korean livestream. I bet it will be awesome :)

[@robspl]

It all looks amazing. This is how the future is built. However, I am keeping a close eye on long-term durability. The fact that it will be on spikes, in my opinion, does not necessarily mean that it will be durable during longer use. Elite can replace these spikes whenever they want, so the only thing that is really known for now is that you can use this material hard. How long? We'll see, I keep my fingers crossed!

[@kofuzi]

I will concede that the use of the material in a spike is not direct proof that the material has durability, but I think we should also recognize that there is no direct proof one way or the other (otherwise we would just refer to that longevity data). stay tuned for the 100 mile review.

[@RoshanFernandez-md5cf]

Great video 🙌🏽, thank you. Would love to try them but the price 😱. May be more tempted with the little talked about but crazy light 361 miro nude 110g 😮.

[@Scott_Graham]

It's giving me early 2000's And 1 slip on basketball shoe vibes.

[@juandiegozubillaga]

Kristian Blummenfelt using this shoes at Kona IM was awesome

[@kofuzi]

did he go sockless?

[@Simo.PT.]

​@@kofuzino. Fun fact: On scanned his feet but he preferred the model from another athlete

[@thediton]

On goes from extremely long laces for the standard cloudboom strike to ‘no laces are required’ for this LS

[@kofuzi]

it's like Mattingly's sideburns

[@philipwood7673]

What's the durability for these and the standard Cloudboom Strike? Do they still come with the 4 marathons warning that the Cloudboom Echo 3 did?

[@kofuzi]

it did not come with the same warning

[@therapygrind]

Ventilation & moisture management? Does ON have anything to say about how the shoe handles the environment, cold & heat, foot swelling, etc? I noticed you splashed in some puddles in the Cloud Surfer scenes but not this shoe...

[@kofuzi]

I wouldn't read too much into the splashing. I can't control the weather. If there's puddles, I'll run through them. If there aren't, I won't hold a review video in the hopes that some might arise.

[@kofuzi]

the foam is pebax that is partially bio-based. I would anticipate that the shoe handles cold temperatures as well as other pebax compounds (I want to call this a bio pebax, but bio pebax is a trade name and there must be a reason why On doesn't use that phrase).

[@Dogwalkerdave]

Did they mention to you when they would be available? I can’t imagine the price here in Canada 😳. They look amazing though.

[@kofuzi]

I tend to forget to ask about when shoes will become available

[@Dogwalkerdave]

@ no worries.

[@Manuel-901]

Hi. Crazy expensive=No for me. Like from 🇪🇸 Spain. A nice week for everyone.

[@glennjthompson332]

"The Bionic Runner Adventure"🏃😁👍

[@MAmir-dl2iz]

Is it breathable tho?

[@sluggle7694]

I assume not if it’s a solid upper.

[@levandmarthapolyakin-aaron2183]

On his LS, kofuzi blew into it and declared that it was surprisingly breathable, though I wouldn’t have thought that possible with anything but a fabric.

[@laalaa99stl]

You can definitely 3D print TPU (or whatever On is using) to incorporate air holes. I think Mr. Fuzi would have said something if his feet were heating up.

[@garethevans2499]

Random aside: do your neighbours pester you for shoe advice? They must do, right?

[@Wieeeeee]

Is it water resistant? 💦

[@XavierV37]

The upper is cool but if they can adjust foam and rubber pads custom to my feet they will hit the holy grail

[@alexeihensel6257]

This is so cool.

[@rubarb1275]

Cloudy with a chance of meatballs! 😂

[@kofuzi]

love that movie

[@kofuzi]

hope you enjoy!

[@31_pandeputuarymahendra58]

what do you think about 2XU Compression Ko?

[@pastorbeaucoffman2214]

Could you wear without socks?

[@kofuzi]

I'm not sure the insole/midsole part that you stand on would be comfortable for that, but there's nothing about the upper that would prevent it (other than the fact that the upper is semi translucent and your toes would be visible. I remember when the zoom fly sp came out and there was a sail version. the potential for seeing toes really bothered a lot of people

[@prateekrajbhandari]

I want to be tied to the ON table while the bot sprays the upper directly on my foot. That's the only way my weirdly shaped foot is going to get justice!

[@chandratamang6381]

wow ❤

[@kofuzi]

yo

[@AndrewMosc]

Maybe it’s me but I thought that using the robot and the tech would decrease the production price of the shoes and that this would be passed onto the customer……silly me 😂

[@kofuzi]

I think you are assuming that the current pricing would reflect the end stage of the benefits of economic scale. from what I understand, we are at the very beginning

[@frre9302]

It misses a stryd mount! ;)

[@kofuzi]

this and the Peg Turbo Shield are not Stryd compatible

[@samuelrice7684]

How do you like the new 2XU compression tights? $160 but they look great…just curious about function. Thanks!

[@kofuzi]

omg, they are instantly my favorite session tights. they've got lots of pockets and I love the graduated/targeted compression. it's overkill for a regular easy run, but for a workout in chilly temps, they're going to be the first ones that I reach for

[@samuelrice7684]

@kofuzi appreciate the feedback! Do you have any link or anything for kickback?

[@brianway4240]

Now I will admit I may have missed something, but I don't remember hearing the word 'lockdown' in this. I really admire the omission and consider this a big step forward for Kofuzi. I am not kidding. ShoeTubers seem to have invented the term in relation to shoes. I have never experienced nor sought lockdown. I have never wondered how much lockdown a shoe possessed. How could I when it didn't exist? I had never heard of it prior to KZbin's popularity. I am not being sarcastic in the least. Keep this up!

[@levandmarthapolyakin-aaron2183]

Well, most of us have experienced the phenomenon when it’s lacking, whether you had heard that word or not. When a shoe feels like your foot is wallowing around in a shoe in any way instead of feeling like an extension of your foot (ideally, you’re not thinking at all about the shoe when things fit right), it’s very frustrating. Everyone’s foot is different in relation to every model of shoe. When too many runners complain of the same thing--either a lacing system that’s not cinching securely, or a heel that too many runners tend to slide out of too easily to give 2 examples--then that shoe may have a flaw or at least weakness in that department. What else would you propose to call that phenomenon and why do you deny that it exists? At the very least, one should be able to state that “for me, the lack of supportive elements combined with the voluminous toebox of the Rebel 4 didn’t provide a secure lockdown”-for a personal example.

[@brianway4240]

@levandmarthapolyakin-aaron2183 You claim lockdown exists. Did you make such a claim prior to KZbin existence? I don't think anybody did.

[@laalaa99stl]

Halo product. Designed to get you to come into the store -- and buy a different On shoe. I don't see this tech ever trickling down to the rest of us.

[@kofuzi]

someone else mentioned it in the comments already, but there is currently concepts of a plan to put this into a wide variety of shoes. when On found this technology, the inventor was suggesting that it could be used for kids shoes, casual shoes, and performance product.

[@SerjiRun]

Omg🎉

[@hahaheslop]

ON's lineup is so confusing. The price is putting me off wanting to try more of them. I got a pair of Cloudrunner 2, but I wouldn't run in them. Stiff as hell.

[@SageRites]

The upper on these is so bad 😢

[@kofuzi]

sorry you didn't like them when you tried them on

[@MainUkraine]

On Cloud shoes have really been overpriced just for show garbage basically so I'm going into this with massive copium 😂 On Cloud really needs banger shoes if they want to prove that they are not just another Gucci

I think Metaspeed may be the only shoes lighter. Deviante Nitro Elite 3 is slightly heavier.

[@alb.1911]

This new clouds windows are useless, they exist just for esthetic purpose.

[@kofuzi]

I think I could agree that there might be a non-cloud way of achieving a similar result with this foam (e.g. cutouts of the Adios Pro 3), but I think to say the clouds in this shoe are vestigial or decorative would be a bit of an overstatement but maybe I am reading your comment too literally

[@noreligion76]

on cloud, no good for running,!!!
