Whats the consensus on the New Balance 890v8 for lightweight performance? Ive seen the specs and it looks like theyve managed to shave off some serious weight without sacrificing much in terms of support and stability. But can it really deliver on the promise of a responsive and springy ride? How does it compare to other lightweight trainers on the market, like the Nike Vaporfly or the Brooks Ghost? And are the trade-offs in terms of durability and traction worth it for the added speed and agility? Has anyone put the 890v8 through its paces and come out with some real-world insights on whether its a game-changer or just another flash in the pan?
