The cushioning factor does increase as distance goes up, yes, but then should Shelby's 14:23 have been a 14:18 or faster?
Yes for Shelby. That's my gut. I was thinking about that this morning.
Although I'd like to know the following to be sure.
1) When Karissa and Shelby were working out before that 5000 last year, what spikes were they wearing in practice? Was Shelby also working out in the old spikes? Because I saw Shelby say recentlly she knew she was in sub 1430 shape but also knew that Karissa was as well. I'd feel a lot stronger in my "yes" answer if Shelby wasn't working out in the super spikes. I say that because it's clear that Karissa was close to Shelby in practice. So I'd like to know what spikes they were wearing in practice wearing before that 5000. Does anyone know?
2) Also, what about during the 3000 when the Shelby lost to Karissa. Does anyone know what spikes they both wore?[/b]
You can find what spikes they were wprking out in on instagram rojo
If your saying the spikes makes over 5+ second difference , do you not think the athletes who've been testing these spikes out for 2+ years and are more intimately familiar with it than anyone else in the world would not notice this massive difference?
Colleen Quickley, Shelby Houlihan and Frierichs who've all been competing in inferior spikes are either ignorant to what is obvious to everyone else or choosing to compete at a disadvantage.
As recently as the Arizona 3k you can see Quickley wearing Old BTC Mamba spikes and beating both Cranny and Schweizer wearing dragonflys.
Look I agree the spikes makes a marginal difference but the benefit they confer is being wholly exaggerated here.
Also how does Gudaf Tseguy figure into this? 3:53 in old adidas spikes. What's she doing in DF's, 3:51 indoors?? 3:48 outdoors??
Also worth noting that Laura Muir had these spikes from start of 2019 and is yet to PB in them in the 1500. Her 3:55 from Paris 2016 was a solo effort for 700 yet she still can't beat it. Dibaba also had for 2 years and hasn't come close to getting a PB.
Not to mention T Cheruiyot hasn't got a 1500 PB yet in the DF era.
This really doesn't seem like the super road shoes, at least not as cut and dry. You've got some of the greatest runners of this generation not PBing, while greats in DFs get stomped by people not in DFs, while people like Shelby Houlihan stuck with old shoes and still knocked fifteen seconds off her 5k PB.
I think people may also need to consider placing more emphasis on the so called covid effect, and on lack of drug testing. Too many conflicting variables right now.
