He ran 27:40's a couple years ago in a poorly paced Payton Jordan race, his 27:14 is finally running what his 5k times show he is capable of for 10k. The spikes probably do help a little bit, but no way it's 30-40 seconds in a 10k, I'd give you maybe 10-15 seconds. So this would be like a 27:28 in old spikes. And probably 27:50 in 1980 spikes, and probably 28:15 in 1940 spikes on a cinder track. There are always going to be improved surfaces and shoes, get over it. Eventually there will be some material that allows for a one ounce spike that still has supportive structure and people will run even faster.
The big difference is up until now, the main goal of a racing shoe was to essentially prevent the least amount of energy loss and still providing some cushioning. The adidas boost material was a big breakthrough because they would return something like 85-90% of the runners energy.
These shoes are a completely different story. The material is not only not losing much energy due to the cushioning, but giving you added return due to the carbon fiber plate. If you haven’t run in a carbon fiber plated “super shoe” then you should refrain from commenting. As soon as you wear one, you instantly realize this is something that really is changing the sport for the worst
It is impossible, literally against the laws of physics, for a shoe to return more energy than is put into it. If Nike managed to do this then you best believe I’m buying electrical and water from them too.
