Would Usain Bolt have run sub 5 in the new Nike 100m track spikes?

0/10

Those look awful. Who wants an air cushion in 100m spikes?

These guys have all the power they want. It is just a matter of translating it to the ground as fast as possible. That probably slows their steps.

I understand sprinters slow the last 30m or so. I still think generating power faster works better for them than having a slight advantage in the last 30m, if those spikes provide one.
