£200+ !?!?

Seems like marketing bulls**t to me. It might make the difference to a Kipchoge for example, the difference between breaking the world record by 5 seconds, or missing out by 20 seconds...

But 99.99% of the running population (myself included) would benefit a lot more from just training better.

Should add that I've not tried them... although I am considering some (cheaper) Nikes for my next road shoes.
