I’ve noticed that many of the records (or near records in Jakob’s case) have been run in the new white Nike prototypes. Notably these are mostly worn in Diamond League events by those who are pushing the boundaries (faith, gidey, tsegay, jakob) but they weren’t worn at worlds, potentially due to them not being available to other competitors.
obviously spike tech has made a huge difference in the middle/long distance since the dragonfly (+ others) but are the top Nike athletes sitting on the next breakthrough? Is this why so many records were set this year?
