Let's not forget that the 10,000 WR has only improved by 1 sec/mile, and the 5,000 WR even less. The super spikes aren't that super.
Let's not forget that the previous 10,000m WR had dozens of years of attempts with similar training knowledge as now. The superspikes have been widely available about two seasons.
Point taken.
But look at the road. In 5+ years of super shoes, with higher stack heights and thus presumably more effect, the marathon WR improved by 3 seconds per mile.
From 2009 to 2014, it was 2 seconds per mile. So, maybe 1 - 2 seconds per mile on the road that can be attributed to the super shoes.
I know it's more in the half marathon, but people weren't really going for that 2011 - 2016.
It's fun to talk about. I remember an old picture of, I think Brendan Foster?, running a fast, for the time, 10,000 on a cinder track in a driving rain with about an inch of water in lane one.
His PR was 27:30. Put him in the conditions they had Sunday and what could he, Viren, Bedford, Lopes, etc run?
