Diadora Nucleo 2

Diadora Nucleo 2 review: what runners say

Fit

True to size. The semi-gusseted tongue keeps the foot contained; the heel is heavily padded with a collar that extends over the Achilles.

Feel

Two-character cushioning: heel feels firm and structured, forefoot soft and yielding. The compressed EVA foam has high density (54 Shore) but delivers no energy return.

Durability

D5000 (Duratech 5000) high-abrasion-resistance outsole. Estimated 500–600 km based on early impressions; no long-term mileage data verified.

Best for

Daily trainer for high volume, particularly for runners seeking lateral and medial structure without a declared motion-control shoe. Well-suited for medium and long runs; less ideal on hot days due to poor breathability.

Weak points

High price at $160 for a daily trainer. The upper is poorly breathable and the toe box area has been flagged as fragile.
