the 4% shoes give apprx 1:30 gain in a marathon, prove me wrong

i noticed in berlin that legese and lemma had on the fake spring shoes like KB...main difference is theirs looked like they were 2 sizes too big and flopping around big time. after they finished they both had noticeable limps more than likely blisters from all that flopping around their feet were doing in HUGE shoes.

anyways if this was the first time they used the shoes we can see the trend

a whopping 4:31 difference...but if you take off 1:30 i would have put here at 2:15:34, very close indeed to paulas male pace WR 2:15:25.

if we take off 1:30 from her 2:18:35 we get a 2:17:05 very very close to the womens only WR 2:17:01

well lets see what you got LRers

so we see that both kipchoge and KB ran around 2:03 flat in legit shoes, now both have run 2:01:38-41 in fake spring shoes.

so lest see what conclusion we can make with seeing other runners what they ran as a PR before they used the fake shoes....and no rek you are not invited to participate

They're not fake shoes, as you claim. They're real and they're no different from Converse All Stars. You just don't like Kipchoge because you have a mean soul. Anyone can do what they've done, but you need to work harder. Kipchoge and Kosgei are two of the best human specimens we've ever seen. Why can't you see that? Why do you think they can't run that fast? They're the best runners we've ever seen on the road-racing circuit, and we're just too insecure to respect their great sacrifice for us all. They're just trying to show us how great we all can be, and they're not even making any money from this. That's how great they are!

Oh -- is that an option? Can we start threads as invite only? Can we start threads and make ground rules? I don't want to deter you, or make you second guess, but I agree with the premise that the shoes help explain the recent spate of fast times. The only comment I will make is that (I thought) the rigidity of the carbon fiber plates are like the opposite of springs, but the foam is springy. But as you wish, I won't interfere with your data research. First and last post. Carry on.

Just curious if you make any posts that are not critical, not inflammatory, or are positive...?

I certainly can't prove you wrong.

But my guess is that you get a 1:30ish gain if you're a very low 2 hour marathoner. If you're slower than that (2:30, 3:00, etc.) I would think you stand to gain much more than 90 seconds.

wow you got me gary....the burn and devastation is sooooo brutal.

Interesting, but we would need more data points. Considering a lot of the elite runners are using nike's now (at least that's what it seems like when you watch the broadcasts), can the net be expanded to see if a pattern emerges?

one more thing i noticed...KB has never ever been this lean! holy hell in his 12:37 days he looks "soft" compared to how lean he looked in berlin. other things, when he took the lead he was running on pure hate, and after he finished and he was sideways to the camera he looked increadibly similar to Emperor Haile Selassie with that goatee he is sporting now.

el K or anyone claiming they are in the know of east africa....is KB releated at all to that line of genetics?
