Nike Zoom Fly 6

Nike Zoom Fly 6 review: what runners say

Fit

Snug fit, true to size according to the majority of sources, though one Italian source recommends sizing up half a size. Narrow and shallow toe box: runners with wide feet or a wide forefoot will find the shoe restrictive.

Feel

Moderate cushioning with a dual-layer ZoomX/SR-02 midsole and Flyplate carbon plate: livelier response than predecessors, but the overall ride is flatter and less responsive than other super trainers in the category. The flexible plate supports transitions without delivering pronounced propulsion.

Durability

Waffle-pattern rubber outsole with negligible wear after 100 miles; estimated lifespan above 375 miles. The SR-02 bottom layer protects the midsole better than the pure ZoomX found in racing shoes.

Best for

Super trainer for quality work: tempo runs, fartleks, intervals, and fast-paced long runs at 6:30–8:00 min/mile pace. Also suitable for runners new to carbon-plate shoes and marathon runners finishing above 3 hours.

Weak points

Narrow and short toe box: a recurring issue in three out of four sources. ZoomX feel is dampened by the pairing with SR-02, resulting in a flatter ride compared to competitors such as the Hoka Mach X 2, Saucony Endorphin Speed 4, and Puma Deviate Nitro 3. One source reports foot numbness on runs longer than one hour.
