Excellent work from the DOR. This is the kind of shoe geekery (tm) that we need more of. Perhaps try to get a materials scientist on from one of the companies (doubtful they'd get to say much, but maybe worth a try). EC Frederick used to run the Nike sportslab and publish some of their research a long time ago. Reading some of those papers was interesting. I'm really interested in the interaction between weight/ force/ running velocity in relation to these shoes. As a heavier runner these days (~200lbs) it seems to me that my slower pace is still going to load the foams with similar forces but over longer time/ lower rate than a much lighter faster runner. But the resilience might be different at different rates? Just some thoughts..
I did a 10k trail race in Prescott Arizona and running through the dell's was nightmarishly hard. Also the Lake Padeden mud run 10k in bellingham Washington was crazy hard.
Cross country 3 mile race in 95f heat and humidity. The opposing teams coach made their team stop and our coach had us keep running. None of us knew the other team dropped out. Then our top runner finished and passed out on the line. Ambulance came and helped him and the varsity race was cancelled lol
This episode was just EPIC! So much information and knowledge spread to us all. I think it requires to be listened three or four times to fully appreciate and adsorbe all the information provided. Great job guys!
The title reads ''.....Sub 2 hours'' yeah by 6 minutes plus !!! Why put me through such a coundrum, both an interesting topic and 2 hours of a video. Now I have to make some time late in the evening and listen the whole lot! :)
Great episode for us shoe geeks. My next question would be looking at the resilience/compliance of the whole midsole system beyond just the foam. i.e. the invincible with just a slab of zoom x most likely behaves way differently than the Vaporfly where the carbon plate not only adds system resilience but also stabilizes the foam. That’s where shoe design becomes hand in hand beyond just the foam.
Good stuff. I wish we had these super shoes back in the day when I was fast! Just from my own research the superfoams really arent doing me much good compared to basic foams. (My times are essentially the same over all distances) although the superfoams do feel much more cush.....
Yeah if you look at the record progression, they barely dropped since the introduction of the super shoes. That could just be the normal progression of more attempts/athletes and fine tuning training regimens. I am more curious on the middle distance track super spikes though, since they are adding the foam where pretty much none existed before (not a track runner so not certain).
Repetition compulsion might be the closest psychological dynamic In a general context, it means replicating earlier trauma often childhood trauma. The explanation is the person experiences repition compulsion is attempting to control and master these experience. In sports, it sometimes relates to improvement and seeking 'perfection. (All of this is oversimplification on my part)
Ha! I thought Altra saying “the foam is a supercritical TPE based material” was all fancy and stuff. Makes me suspect more now though that it’s a supercritical TPU/EVA blend mystery foam. Regardless, love the shoe.
Interestingly, there is the study: "Influence of different midsole foam in advanced footwear technology use on running economy and biomechanics in trained runners" which says the PEBA foam performs worse in the long run (no pun intended) after 450 km, compared to EVA. In my personal experience (being running consistently for 28 years), PEBA is more durable 600km in the Pro 3 - 700km in the Pro 2 and it performs far better. I've never run that far in any EVA foam running shoes, being able to push sub 4 minute per km comfortably, even if the shoes are worn out.
@@cannibalmanimal2336 Of course it's me, after having tested 8 pairs of running shoes with PEBA foam at the running track (following the same "protocol"). After clocking 700km using the Saucony Pro 2 and Pro 3. Feel free to run in EVA foam shoes as much as you like.
Of course it's about me. After having tested 8 pairs of carbon plated shoes (PEBA/PEBAX based) at the running track, following the same "protocol". After clocking 700km using the Saucony Pro 2 and Pro 3. Feel free to run in EVA foam shoes as much as you like.
Hardest race - probably 800m track (previously the shortest distance I had run was 5K. Half-marathon was my main event). 800m was a whole new level of pain
Your point on how people interact with shoes differently than other people is why I’m so frustrated about the amount of people begging for running comparisons on RU-vid. There’s running stores for a reason.
so basically I just need to buy one boost shoe per year from adidas for easy miles, run all my workouts in the saucony endorphin speed and race in the vaporfly. sounds like a good rotation for my ears
Easy this year (I am an older runner with only a few years under my belt so not an extensive list but I have done a couple of spartan including the ultra). On February 20th this year Blackpool Lancashire UK, A half Marathon was run in the middle of Storm Franklin (winds of 38-50 mph ) .. that was pretty tough especially when it was a headwind and horizontal sleet .. but I was buzzing when it was finished :). however though I am 53 I am a young runner, so still running a lot of PB's and have yet to face my toughest running challenge
