What about compressed rubber? It's been known for a while that EVA gives simply by how it is made.
As I understand it, Nike does not simply use plastic.....it is a polymer. I think it a similar polymer used in handguns (probably has a conglomerate of materials). I'm not aware of any studies, but I would venture and say that a polymer can be made more stable and tougher than wood. The only positive factor that a wood heel has is that it resonates with a wooden platform better.
@snatch147at85 Thank you for your comment. I like rubber, certainly, for flat shoes. For a shoe with a heel, it's heavier than wood, and, again, no resonance with wood platform. I love wood because- it does mold to your feet, then maintain shape-- much like the hull of a yacht. I can't get plastic to mold to my feet, and I can't feel the floor with it. As an engineer. I'd like to keep progressing shoe technology-- but as they say - "if it ain't broke, then don't fix it".
Just another thought after the world comp ended...- only seen Group A n B lifting n I ve noticed that many of these elite lifters where wearing "cheap" EVA heels, n some of them seemed to have done pretty well as they managed to get to a podium position. I wonder if, according to ur study, they were wearing wood heels they might have put on 20kg on their total :)
Great effort! but... perhaps EVA heels are something you need some time to get use to? since Yoni might have been using wood heel all his career... ? just a thought..
The new adidas that r gonna be introduced at next year olympics (don t remember how they r called) have a plastic heel. adidas is the lader in the making of W-shoes and they have chosen a plasic heel instead of the old more traditional wood heel. I understand your intention I'm making a small study but I don't think is acceptable making suggestions based on such limited findings.
Thanks for the quick reply, I think that a fair point to make would be that your lifter might not like those shoes, or he s not used to lift in those. Maybe they just don't suit his feet/style of lifting etc. I have bought a pair of nike (plastic heel) n I did regret it because I found em heavy n too hard/rigid compared to my old adidas, having said that, the chinese team seem to be lifting pretty well wearing nike.
hello there, I wanted to ask: was the experiment carried out the other way round? eva shoe first wood after? were the shoes equal in size n height of heel?
were the shoes tested with a high no. of different lifters? (i.e. 100 different elite lifters), so that shoe preference would not be factor? thanks Sauro
@zedgarden this is a, simple, realtime demonstration. No staging, no editing. This is more like a PBS experiment or pilot test. Yes, to do a full DOE, you would want to do more replicates, choose blocking variables, etc..
The sample size would not need to be more than a few lifters as there are less than 100 77's in the WORLD who lift at Yoni's level. This video was meant to be something short, raw, and unedited for youtube. It makes a point.
Well-done, thank you guys for furthering the cause of evidence-based practice in the sport of weightlifting, and for advocating for wooden heels as essential ingredients in top flight lifting shoes!
not a blinded study. There is potentially user and observer bias in this video.

zedgarden,
(1) This video has nothing to do with Adidas
(2) Perhaps, you should ask Nike, Adidas, Reebok, etc to post studies on plastic heels.
(2a) Ask them how much money they save by using plastic and not wood.
