Diadora Frequenza 2 review: what runners say

Fit

Fit runs true to size according to the Italian source, which recommends ordering your usual size with no half-size adjustment. Multiple English-language sources report the opposite: a narrow toe box prone to toe irritation, recommending sizing up a half size.

Feel

Anima N2 nitrogen-supercritical EVA midsole: soft on impact, responsive at speed. The shoe doesn't do the work for you — it demands effort — but returns energy cleanly without feeling mushy.

Durability

Duratech 5000 rubber on the heel, soft rubber on the forefoot. Estimated lifespan up to 600 km even for runners over 165 lbs. Minimal wear observed after approximately 30 miles in source testing.

Best for

Plateless midsole suited for fast training, quality sessions, and races up to the half marathon. Also viable as a daily trainer for runners hitting 6:26–9:40 min/mile pace. Not recommended for heavier runners with stability needs.

Weak points

Narrow toe box: a recurring, structural issue flagged by multiple independent sources, with reported cases of pain and inability to run in the standard size. The $175–180 price point is considered toward the upper limit of the segment by several reviewers.
