Much like the road bikes that cost as much as a sedan, unless you are competing on a world stage, these aren’t meant for you.
I’m sure someone will happily sell them to you if you enjoy wasting money.

There’s a lot of people trying to get a 3 hour marathon or some other goal where chasing the marginal gains is worth the cost to them.
You don't need to be competing on the world stage to enjoy some of the benefits of Alpha flys or those pumas. 500 for the new Adidas does seem a little silly though.
