What They NEVER Tell You About Running Shoes

[@benjamin.kelley]

Shoes were made to help "solve" a problem because we created hard road surfaces. Sure, running barefoot through grass and dirt would be ideal, but we don't really have spots in most major communities where that's an option. For years most people have been walking around in shoes, too tight around their feet, and with collapsible foam and rubber, making their feet and leg muscles underdevelop. The same goes for "stability" shoes. You need to develop the muscles to stabilize your body - you can't just pick up a pair of shoes that will "fix" instability - in fact, most of the time shoes like this will actually cause rubbing issues and make you have even more instability problems. When I was 12 or 13 I had orthotics and after about a year and a half I decided to toss them in the trash because they helping with my flat feet - which never really seemed to be an issue anyway because my legs, hips, knees, calves or anything didn't hurt - and with my logically thinking mind, I thought about it for a while and came to the conclusion that unless I actually do exercises to promote building and Arch in my foot and better Achilles and calf strength, orthotics won't do anything but be annoying plates in my shoes that raise my feet and make shoes uncomfortable. That's why I try to run in shoes that mimic a natural foot strike, with a wide toe box, minimal heel to toe drop, and lots of hard ground feel. Sure, in a marathon my feet start to hurt a little bit after 20 mi, but I'd rather feel that way than have a ton of injuries all the time. I run in Newton Running shoes.

[@joesirbak2103]

Perfect timing, James! I was about to head out for a long run using my Invincibles (coincidentally in the same blue/orange color scheme you keep showing in the video 😂). I've always noticed more knee soreness after running in the Invincibles but didn't understand why. I'll be swapping in my SuperBlasts (my all time favorite shoe) for today's long run instead. One note of criticism though - this video is almost comically repetitive. I'd recommend re-editing it down to half the length.

[@Steffne2743]

So you´re swapping one mega cushioned shoe for another? 🤣

[@joesirbak2103]

Yes, while the Superblasts have a huge stack height, they feel much firmer and responsive, while the Invincibles are mushy - incredibly comfortable during the run but causing more discomfort afterwards, possibly for the reasons James articulates in the video. (At least that's my experience given my body stature and running mechanics). Maybe I'll try something less maximalist in my next pair.

[@benreed22]

I blame my invincible 1's that gave me a long term Mcl injury !!! - just to soft

[@wertacus]

Anecdotal, but for me, I recently got my first pair of high stack carbon plated shoes, and while they make me objectively faster, they feel much less stable than more "pedestrian" shoes. I feel like I get more glute activation with them. I used to wear running shoes for daily use but have switched to shoes with no support for daily wear, and I feel that has helped strengthen my feet so I can keep wearing highly cusioned shoes for runs. I think it can be valuable to have a rotation of shoes with different profiles

[@vincentaurelius2390]

Exactly my logic. I walk around in Altra Escalante zero-drop shoes and run in Saucony Endorphin Pros.

[@metkacebulowa]

Very complex explanations, professional and clear for casual person. Great, thanks!

[@thadstuart8544]

I believe if every runner were to run barefoot on a treadmill, it would change their view on an appropriate shoe. I would have SWORE I was striking mid foot. But, when I ran barefoot, I immediately felt my heel striking which was painful and not sustainable. So I naturally transitioned to a forefoot strike, which is the only way to run naturally. I have since bought a few pairs of Xero shoes and zero drop Altra's. All my other shoes (Hoka's, Saucony, Asics, etc) I only wear casually now. I now focus on forefoot landing and all my aches and pains have disappeared. The documentary on "Born to Run" and the book itself is highly recommended about this subject

[@crisissocoylike446]

Ty for your information comment

[@eddielynch7697]

I agree definitely that many people get cushioned shoes when they shouldn’t be, basically just how the video says. However, if you are running on hard surfaces (ie not off-road), then barefoot shoes are simply too harsh on the body for running. I have always tended to go for shoes that more bare bones, with a good layer of foam but are the shoes that are generally described as firm and responsive due to them being more minimalist. You also have to be careful with forefoot striking over long distances because it can put huge amounts of strain on the Achilles and the calves, because when running long distances we are not designed to forefoot strike. However, this is nuanced, as landing on the forefoot and then allowing the foot to rock back on the heel is very good when done perfectly. I will also add that heel striking is also completely fine if done correctly, and everyone is different so some will be better off doing one or the other

[@jam3sbrad3y]

Spent over 500 on all the new running shoes when I got back into it a month ago. Thought i was good to go. I ramped up the miles weekly, started upping my pace and then... i ended up in a boot lol. Luckily its not terrible but two weeks off of training has been rough. Now im studying foot mechanics and doing rehab in barefoot shoes. Foot/leg mechanics is far more important than cushion. Cant wait to get back , and better!!

[@SimonWatkinson-n6u]

barefoot minimilist shoes are the way to go if you want long term no / reduced injuries . its all out there , read born to run etc , flat shoes wide toes box , minimal padding , transition slowly , save huge amount on shoes as they last much longer and cheaper 😂 best of luck , do the research its all out there - read some Dr Mark Cucuzella

[@mikepeligro]

I initially started running in minimalist bareform shoes such as plimsoles, water shoes, and the Merrell Trail glove series (1-5) for six years. Bareform running mechanics strengthened my calf muscles, tendons, and plantar fascia. I was able to run half-marathons in minimalist shoes within the 2 hour and 20 minute time frame. I got sore for a week after a half-marathon, but the bareform training provided enough stimulus to toughen up my muscles and tendons. It also taught me how to land on my midfoot, engaging my calves and tendons in the right way. I stopped running during the pandemic years and switched to cycling instead. Fast forward to 2024 this year, I started running again. This time, I used the supershoe Nike Vaporfly 3 as a daily trainer. Yes, that's right, as a daily trainer. I didn't experience any stability issues brought by the high stack height because I engaged in rollerblading and ice skating as cross-training activities. Rollerblading and ice skating are two of the very best sports that train your stabilizer muscles in the core and lower body. I trained for three months in the Vaporfly 3 and I felt so great. No foot and muscle pain after a run. The supershoe indeed absorbed the normal shocks and pounding forces of running. After running a half-marathon in the supershoe, the next day I was able to run again normally as if the half-marathon effort the previous day never happened. I wasn't sore at all. This is how I think what happened to me. The six years of running in minimalist shoes toughened up my running muscles and taught me proper running form. Then I moved up to supershoes which made it even easier for my body to run comfortably. In the future, I plan to go back to minimalist shoes while training, then use supershoes only during race day. This will give me the best of both worlds. Tough training and maximum adaptation during normal days using minimalist shoes, comfort and speed to push myself even further on race day by wearing supershoes.

[@garthcox4307]

This made a lot of sense with the experience I've had. I've never really got on with highly cushioned shoes. I found the nimbus the worst, the novablast 4 is as cushioned as I want to go for easy runs. I have a rotation of 4 shoes, mostly with different stack heights.

[@ArkiTalo]

This is true especially with more cushion shoes, as a heavy runner more cushion gives my body to counter the balance which leads to more muscles being used. That's the reason why I switched to more firmer and says 50/50 stiffness and cushion. Makes me feel my legs relaxed even after the long run.

[@qigong1001]

Yup, my cushion shoes encouraged my overstride, nearly destroyed the ligaments in the back of my knee. Took months to retrain.

[@ButtersOhh]

I switched to ultra running shoes. Zero drop. Medium cushioning. Very flexible. I've never felt better. My running foam has improved And I've had less injuries.

[@chrissellers4519]

Great content James. This just adds weight to having a few different shoes to rotate. I like high stack carbon, but enjoy trail running and also my Brooks that feel like bricks!

[@DonGivani]

True, I would recommend everyone to do a Knee-to-Wall test . This is to check if your achilles are shortened by cushioned shoes

[@smellysam]

In my experience, to access the benefits of superfoams, I need to be even more precise in my whole gait from foot strike to push off - or I will just sink into them and be slow... Plated shoes also allow for push of from closer to the tippy toes... Lovely, but you need to run lower, work a lot on flexibility and strengthen both the quads and the calves... So there's no free lunch here - or you will fall into the characteristics described in the pinned study.

[@spb_sticks]

great insight James! would you recommend different shoes based on your age and whether your running is improving with time and/or distance? I’ve been in neutral shoes - Brooks Ghost - but curious to look into other brands and will check out the foam type after this video! 😊

[@remcov3253]

WOW 2 minutes in and I already agree. I run about 1000 to 1500 km a year and shoes never last met longer than 600 - 700 km due too length and weight of my body. I have noticed I run worse biomechanically on soft shoes. I analysed 5y of running using runalyze did various ANOVA's and turns out that I run uneven on soft shoes. Uneven in Ground contact time balance. I bought harder shoes using runrepeat analysis data and wow. Immediately the new pair run perfectly back in balance. I also ran easier in those shoes.

[@marycalvert3887]

[@diktromdefilm]

Yeah, my intuition always told me to feel the ground is better. Better performance when sprinting. Better muscle acrivation in your whole leg which protects knees andd hips and protects you from running too much too soon;)

[@MartinCharlton-ds7ro]

The biggest problem I find is that you identify shoes that you get on well with and then the next version just doesn’t feel the same - a prime example would be the Saucony Speed versions 2 & 3.

[@iiagdtr]

I had a pair of the original Nike Tailwinds. Extreme cushioning that lead to sore Achillles. Since that time I look for shoes, well now a shoe lol, with a more performance oriented ride. For me the Pumas do this well as well as a Hoka X2 I just got. I do have a couple of max cushioned shoes I use sparingly when the legs are beat up from hard workouts but only for a few recovery miles.

[@fulviomichelis1861]

Thanks for this, and you other many super informative videos.

I also have the SL2 as a daily trainer but I feel like that one has a more firm and stable foam so I will be using that for speed workouts as it hasn't given me a problem so far. Admittedly, I have weak feet which results in poor running form so I am actively fixing that to get better value from the Takumi Sen 10s.

I use Altra shoes with zero heel to toe drop, a foot shaped toe box and a stack height of between 22mil (Escalante Racer) and 24mil (Escalante 4). If you're not used to zero drop shoes, break your legs in gently by initially rotating the Altras with your usual shoes. My experience is that once you become accustomed to them, the Altras provide all the cushioning you need without being squishy and giving the unfortunate feeling of running on a couple of foot sized mattresses.

[@Beariam24]

[@antonl1449]

Good advice but i miss a discussion around the rocker in the shoes and plates and how that scan shift th load from the foot, wrist and calves upwards. Brooks Ghost btw has one of the highest drop you can find in a distance shoe. They are pretty firm and normal stack height but definitely not low drop.

[@anniwilson2534]

Finally! I’ve been saying this for years to running clients. The human foot is zero drop and perfectly designed to run minimally shod over long distances, provided the runner has the strength to manage the loads. Another factor in foot biomechanics is toe splay - many running shoes have a tapered, shoe-shaped toebox which inhibits this. When a barefoot lands, the toes naturally splay to initiate landing gear, so why aren’t all running shoes foot-shaped?! I run in Wildsole sandals, Vibram FiveFingers, Vivobarefoot or Altra - depending on duration and terrain.

[@clarenceclutterbuck]

At risk of seeming mildly extreme, I'd venture that the CEO's of all shoe companies that make non-foot shaped athletic shoes should be arraigned to appear at Nuremberg type show trials on charges of crimes against the human foot. 👮‍♂🚓

I currently keep getting plantar fasciitis after I do a long slow runs with 9-10minutes/km pace around 7.5km. So I was thinking to change a new shoes for that, and now this video makes me wonder if shoes with high cushion is actually helping me or hurting me?

I moved to max stack due to a metatarsal issue and whilst it helped, what ive realised now is that working on my hip and leg alignment/weaknesses has had a much bigger positive impact. I now run in 'daily trainers' and it feels more natural and just as protective due to addressing the real issue rather than trying to just cushion it.

Interesting. I agree that well-cushioned shoes can mask poor form. On the other hand, I believe that shoes with minimal or no cushioning would force you to run with a good-enough technique to not feel instant pain but maybe not much better. four years ago, James has a great slow motion video analysis of Kipchoge, explaining this form which I honestly believe is the greatest running instruction video I have ever seen: kzbin.info/www/bejne/l5_HcpSJa7GsmZo . And Kipchoge is wearing high-stack shoes! My take-away was to get the best of both worlds and run in well-cushioned, low-drop shoes and run mindfully, diligently and consciously with good form even though the shoes would forgive poor form to some extent. It seems to be working. I am 57, I am running again after a broken knee (dog impact) two years ago and I am fine. And my current shoes are the Invincible Run 3! I can definitely feel that my foot muscles had a work out when I get out of bed in the morning after a hard 10K the night before. I am not sure what to make of this video. I feel James really should have covered the elite runners using high-stack or well-cushioned shoes in competitions.

I don't think this really helps in choosing the right shoes. I've had gait analysis and running shops use it to see if you over pronate or not. If so, then they recommend Brooks adrenaline or glycerin. I've never had any other insight. Also, I can't afford to buy lots of shoes to try them out and see what works best. I need to able to make a decision in the running store after trying them on and briefly running on a treadmill. Your advice on taking other things into consideration doesn't really say how.

[@DerekPayne1791]

Get closer to the ground and increase your leg weight training.

[@rjsale]

With 27" inside leg 20mm additional stack height (max thickness Vs older) gives an extra 3% effctive leg length, which I think helps make me faster.

[@rjsale]

Also, as a lighter weight runner the carbon-plate shoes felt like clogs. I heard that they used the same thickness and width plate in all sizes so my 58 kg in size 6 was never going to bend the plate sufficiently: now I'm 65 kg they're OK. Carbon plate shoes should really be made with different spring constants for different weight runners.

[@fergusdenoon1255]

Where's the "science" You just saying things isnt "science" People run much further and much more because of max cushion, because they're running farther and more often their improvement is sometimes too much too soon, making them more prone to injury in a shorter time period with far more running in it, if they ran in a low stack shoe instead, they likely wouldn't manage the milage they were previously doing, wouldnt be improving so fast, because of the battering they're doing to their body and the extended recovery periods needed. This can easily ne interpreted as "max cushion damages the body" but it means it damages the body... less. Conclusion: if you took two identical runners, one in low stack, one in max cush, made them do identical training, they'd borrow each others shoes, because running in the same shoe type of shoe all the time isn't optimal.

[@theghostofpcs2391]

I have a special place in my heart for the Invincible Run 1. Back then, it was the only shoe I could run in, that didn't aggravate my knee injury. The lethal combination for me, is firm + rigid (like the Nike Zoom Fly 4 and Adidas Boston 12). The ZF4 actually took me out for nearly a year, and the B12 came close to injuring me. I really love high stack, soft and squishy, but found a great compromise in softness in Adidas' Lightstrike Pro shoes. My most used shoe atm is the 50 mm Prime X 2 strung, which keeps my legs fresh and heart rate lower, so that the demand on recovery is a lot less.
