If anyone's interested, the shoe being purchasable by the general public is a condition of them being deemed legal for pros, after a crackdown on Supershoes a few years ago.

The other conditions as I recall are there is only allowed to be one carbon plate in them and a maximum stack height of 40mm.

It really is incredible that Nike kicked off this Supershoe arms race ten years ago and spent (presumably) an incredible amount on R&D, marketing and hype to try and complete the mission of being the first shoe to go Sub-2, and Adidas has pipped them at the last minute... twice in one race. Oh to be a fly on the wall at HQ today...

Though I assume they made a lot of that cash back in the interim selling these things to weekend warrior suckers like myself!
