An outstandingly fast, light and energetic carbon racer that nearly carried him to a mile PB on tired legs, and he salutes what Adidas achieved technologically. However, at £450 he still wouldn't pay for it, believing similar performance is available from other top-tier carbon racers, and he's more excited to see the tech trickle down to a cheaper, more accessible shoe.
Best for: Fast road racing — he felt great over an all-out mile and suspects the shoe's sweet spot for him is 10k to half marathon; very tall, light milers or track runners may prefer something stiffer, lower-stack and more direct.
+1 earlier review from The Run Testers
One of the best carbon-rim racers Kieran has run in, light and high-energy and great when running well, but very expensive, hard to get, not forgiving when fatigued, and hard to justify for runners slower than three hours.
Best for: Light runners going sub-3 hours who land mid-to-forefoot and can engage the shoe at race pace for long periods
