Blog · Référence Trail – Quentin André · summarized
PositiveRated 4.25/5. He recommends it without hesitation for 50 km+ ultras and 30–40-hour races on runnable paths. Cushioning, width and stability are excellent. Performance on technical ground and grip on greasy soil are limited, and the heel hold could be better.

PositiveRated 4.25/5. An excellent ultra shoe: big cushioning and comfort for 30–40-hour races, with good traction on mixed ground. It isn't dynamic, and the heel hold could be better. At 308 g it is heavy, so take care on technical and greasy terrain.

PositiveStable, with great traction and a comfortable fit for long days. The ride felt flat and lacked oomph, so it didn't match her preferences. Still a top pick for runners who want comfort and stability over speed.

Of the 13 reviews with a clear verdict, 77% are positive, 0% mixed and 23% negative. The praise mentioned most is great for long runs. The most common complaint is narrow fit.
The complaints reviewers mention most: narrow fit (2 reviews), blisters (1 review) and heavy (1 review). For example: For a wide foot the Caldera 7 was wider than the 6 but still not wide enough, with mushy foam and a short fit that needed a half size up.
