On Cloudspark review: what runners say

Fit

Runs narrow and short: sizing up half a size is recommended, in some cases a full size. Narrow-footed runners fare better; those with regular or wide feet may have issues.

Feel

Medium cushioning, firm and responsive feel. The nylon speedboard promotes heel-to-toe transition and drives forward propulsion decisively.

Durability

Durability uncertain according to some sources: the rubber compound is relatively thin and may wear faster for runners with a scraping stride. No precise mileage figures available from sources.

Best for

Up-tempo daily training, progression workouts, races from 5K to 10K. Suited to lighter or mid-weight runners looking for responsiveness and a snug fit. Not designed for long distances at conservative paces.

Weak points

Sizing problematic: multiple reviewers report a narrower and shorter fit than their usual size. Midsole perceived as firm by those seeking generous cushioning.
