If you look closely at this shoe, only about 1/3 of the outsole/undersurface, maybe less, is in contact with the ground. It's like two springs connected by a stiff platform on top under the foot, with an almost continuous rocker from heel to toe under the whole thing. They've even extended the sole beyond the front-end of the toe-box to get a little extra leverage at toe off. Wild!
which is the opposite of what nike has done. more foam sticking off the back.
Real supershoes give their best performance on roads and don't feel that fast on softer surfaces. I'd say a treadmill isn't the best surface for comparison.
…all the reviews that I see are pretty useless. they spend more time talking about the laces and the tongue than the 3.6% improvement.
it’s pretty simple. run your typical 6x1k and see if you are now doing it in 2:53.5 rather than 3:00 with your other super shoes. easy enough. No, I felt good or it felt a little weird running in them. Do you get that extra 3.6% or not. 3.6% is major. You more than notice that. You would be going from a 9:00 3km to an 8:40 3km. That’s approximate 1 year of training to go from 9 to 8:40
I actually got a 6%+ improvement with the 4% (out of the box, then improvement was less already the second time I used them). They also got me injured (but that’s another story). It was not. oh I fell a little strange in them. it was OMG, this is insane. Very verifiable
So in my case, it would be going from 9:32 (normal shoes) to 9:00 with the 4% (because it was 6% for me - super high responder) and then 8:40 with the Puma.
…actually, ChatGPT is telling me to stay away from the Puma since I was such a high responder to the Nike 4%. The percentage improvements do not stack for me unfortunately.
Why do I even bother with this board anymore. CharGPT>Letsrun

Yea I might’ve worded this a little wrong. I meant to direct the criticism at Outside, not him. I was just wondering if anyone else noticed a dip in length/quality/topics, would guess it’s 100% editors not him though.
His writing is awesome, I’ve loved all his books including The Explorers Gene.

Ughh.... How many thousands of times do we need to note the distinction between efficiency gains and time improvements. THEY ARE NOT THE SAME THING.
They use a treadmill designed to more closely replicate running on the road for testing. This wasn’t just a typical gym tread.
Yeah, research-grade treadmills feel just like running on the road. Unfortunately, they cost a fortune, so a lot of research is done on gym treadmills. Important to know which was used when you're reading this stuff.

3.5% better means you go from 4% efficiency improvement to 4.14%. That isn’t big enough to measure with a treadmill run. Getting to 6% would be a 50% improvement not a 3.5%. This is middle school math…. You aren’t going to notice <1s/mile

To be clear, I got a 6% improvement (in seconds/Km) with the Nike 4%. Not “efficiency” gains, not perceived effort…. Actual 6% drop in time. If you watch the videos of the lab test, they are actually talking about people improving their times by 3% (but then you don’t see that in any videos of people “testing” the shoe).

Everyone wants to see real world results, of course. But I think people aren't respecting the lab tests enough. They're pretty good tests. Burning significantly less oxygen at 5k race pace is something that will translate to real running to some extent. And it's also pretty unusual in an experiment to see that every individual had the same result. 15 different runners all burned the least oxygen at 5k race pace in the Pumas compared to Alphafly 3 and Pro Evo 1 (as well as the previous Pumas).
Adam Wood put out a video a while ago about testing them at marathon pace against his preferred shoe and he was also more efficient in them:
I respect the results very much. it scares me. One breakthrough with the supershoes is one thing. Now it's an equally large breakthrough on top of an already huge breakthrough. and here we are, as has been mentioned, floating in the same territory where swimming was all those years ago.
Put the genie back.

Canadian Olympian Rory Linkletter said ahead of attending Boston: ‘Make no mistake, Fast-R NITRO Elite 3 is the most radical ride I’ve ever experienced, and I have the Strava receipts to prove it. It’s certainly the fastest shoe I’ve ever laced up’

I’m wondering if his Apr 5th workout (24km) - 3x5 miles (1 mile float) + 3 miles (average of 2:58/Km for entire workout) at 3100 feet elevation was done with the new Pumas

So you go from 6% to 6.2%. You aren’t going to notice that.
