The Asics Novablast 6 and the Asics Gel-Nimbus 28 are two neutral road shoes built for runners’ daily training. They still play in different lanes: the Novablast 6 bets on responsiveness and versatility, the Gel-Nimbus 28 on cushioning and protection.
The Novablast 6 is lighter: 253 g / 8.9 oz versus 266 g / 9.4 oz for the Gel-Nimbus 28. The Nimbus sits higher: with a 43.5 / 35.5 mm stack against 41.5 / 33.5 mm, it packs more material underfoot. Both share an 8 mm drop and neither carries a plate.
The real difference comes down to the foams.
The Novablast 6 pairs FF Blast Max with a block of FF Blast Turbo² in the forefoot. Turbo² is a new-generation A-TPU foam that outperforms PEBA: essentially the same as the FF Leap found in the Asics Metaspeed racers, in a more durable formula built for training. You feel it in the push-off phases, with a clear energy return when you accelerate.
The Gel-Nimbus 28 relies on FF Blast+, a conventional foam, better than the ECO version it replaces but not a new generation. Asics rounds it out with PureGel in the heel, 65% softer than standard Gel. This package favors shock absorption, not performance.
Despite its XXL dimensions, the Gel-Nimbus 28 keeps good overall stability thanks to its wide base. The feel strikes a fine balance between plush and firm.
Novablast 6 or Gel-Nimbus 28: which should you choose?
Our pick is the Novablast 6, rated 9.5/10. It is the versatile shoe we recommend without hesitation: a pleasant ride, high cushioning, and a wide, planted platform. Easy run, long run or tempo workout, it delivers in every scenario.
The Gel-Nimbus 28 (9.4/10) remains a true do-it-all training shoe. It is a good choice if you are after comfort and protection, and if you are a beginner it will keep you safe through your first strides. Just know that responsiveness is not its strong suit.
That leaves price: the two sit about $15 apart. Better rated and a bit cheaper, the Novablast 6 offers the better value.
