One should self-standardize to an admission time of 30:00 to even race as an amateur in speed shoes
I ran a 10K on the same course under similar conditions 5 years apart, the first time in minimal racing flats and the second time in Next%. My second race was 1.1% faster (calculated as 1 - (fast time / slow time) ).
But I had 5 more years of training in the meantime. And 5 more years of aging (not the good kind). And different approaches to training. Good luck figuring out how much was the shoes.
Based on MY experience, they gave me an advantage of 2mins over the marathon, 1min over the half and following that about 30s in the 10k. This is in line with a study, I once read on these "supershoes", 2 - 3s per k.
What's the weight formula again? For every pound you lose, you lose a second per mile?
Of that's true and you're not that fit, running more and losing weight would be the way to go.
“I wanna get one too.” That’s the only part that matters. If you want them, then go for it.
As for how much of a difference the shoes make, I have no idea but I certainly like the way they feel in comparison to traditional flats.
My experience is about the same. About 4-5 seconds per mile when racing or doing continuous hard tempo runs.
My best 10k time is still from the Pre-super shoe era.
In fact the only PR I’ve run since then was in the 5000m, and that was in Dragonflies.
I don’t think there’s as big of an advantage as many would like to think (maybe in the marathon, due to the higher stack), but they sure do make the experience of running fast a little bit more enjoyable.
Compared to my 13.1 time actually improved by about 4% when I got the original 4% flyknits -- with very similar fitness, similar conditions, same course. Compared to Asics Gel Noosa shoes.
I went from a mile on the flat road in 5.42 wearing a traditional road racing flat. One week later, 5.19 on the track in the next %.
This roughly aligns with my own experience. But of course, it's anybody's guess how much improvement was from the shoes vs. better training.
Agree with the other posters saying 4-5s/mile, when I do workouts in regular flats that's how much I expect to slow down by.
It's possible that they could be worth more for heavier/slower/less efficient runners but I don't have any experience with that.
Also if you were using trainers instead of racing flats before you could expect another 3-5 seconds a mile improvement, or more in the 1 minute range over 10k. This depends on the trainer but if I'm doing a workout in pegasus 38s I expect to be 10s/mile slower than next percents
Why don't you guys post your mile timing or the reps lap time before and after, that way we can see the relationship between the various variable.
It's true the slower the time the more improvement it seem to have, based on my observation. I have seen several 3:00 marathon runners improved by 10 minutes after the shoes, but for 2:30 runners looks like 3-5 min improvement. And then for 2:20 looks like 1-3 minutes.
I see people taking up to 2 minutes off in the 10k. 36 min person in 34s
Forgot to mention, these people use these shoes as a crutch.. I've seen 36 min road 10k people become 42min in XC 10k
Oh, to be 22 yrs old again. My 10K road PR was a 31:56 way back in 1988. Would I be a low 30 min guy with those Next shoes today?
Lowered from 26 min 17 to 26 min 11
So I've tried to do this in a relatively scientific way by running the same race in different shoes but even that isn't perfect as things like sleep, weather etc. are hard to standardize.
My personal finding was my 10K time was about 45 to 50 seconds faster in the 2018 Vaporfly 4% shoes. I just got my new Vaporflies and plan on running them in a 5K tonight.
Interestingly enough my 10K PR wasn't set in super shoes but a 2018 pair of Adidas earlier in the year when I tested out the Vaporflies, I missed it by about 20 seconds which speaks a bit to the challenge of trying to make things apples to apples.

Then I retired.
I mean, this topic has gotten a ton of coverage but I'll still add in some of my usual thoughts. Shoes, alone, don't account for all of the improvement. Training, conditions, recovery, etc., all matter. Pacing matters. You're not gonna run 4% faster if you go out faster than you should.
Elite marathoners were getting ~90s-2:00 bump. Less than that for half marathon & under. Then there's the matter of what super shoes you're wearing & how well you respond to them. Labrat rundown found a 3% running economy boost from the Alphafly's. Now who on here knows if they're getting that full 3% or something different? A 36 minute 10k runner is not a 34 minute 10k runner because they put the shoes on. Maybe they were always a 34 minute runner or learned how to train/race. With a 36 minute 10k, there's still a lot of time on the table from better training. We're almost never getting the perfect recipe for races -- 40-50 degrees, no wind, well rested/recovered, uninterrupted training block, coming off a taper, etc.
The shoe talk is taking away from good performances. Yes, they help. But you still have to go out & execute.
