Asics Novablast 5 review: what runners say

Fit

Slightly narrow fit in the forefoot reported by multiple runners. Works better for wide feet than previous versions.

Feel

Pronounced responsiveness and bounce, optimal between Z2 pace and tempo (roughly 4:30–5:00 min/km). FF Blast MAX foam delivers energy return but tends to pack out with mileage accumulation.

Durability

Midsole perceived as degraded around 300–400 km by heavier runners (85+ kg) running a single-shoe rotation. Outsole shows limited wear; the thin upper gives out first. Realistic expectation: 500 km for runners over 80 kg, potentially more with rotation.

Best for

Daily trainer on asphalt, suited for easy and tempo runs. Not ideal as a sole shoe for high mileage or for runners with a tendency toward overpronation.

Weak points

Midsole loses responsiveness quickly, with multiple runners reporting a flat feel between 250 and 400 km. Insufficient grip on wet asphalt and at higher speeds.
