The problem is not how much they cost, it's the clear and demonstrated competitive advantage. Basically, unless you use these shoes (or competition catches up), you are disadvantaged, unrelated to ability. And before you say 'but bikes,' cycling has always had a mechanical element. You might say that's just a competitive element, but then there needs to be a discussion about the point of the sports, human athleticism or human+technology? Sure, better shoes have always provided some advantage, but it's now clear there's a point where the capability of the athletes peaks and it moves (further) into a technology competition. I feel like we're heading towards transhumanism discussions, perhaps it's time to do so.
