Li-Ning
Feidian 6 Ultra
Li-Ning's flagship marathon racer pairs a tall stack of Super Boom PEBA foam with a two-tier carbon plate that leaves a void under the midfoot. RTINGS found it light and very bouncy but less forgiving than most super shoes, best for strong forefoot strikers.
About the Feidian 6 Ultra
Li-Ning's flagship marathon racer, the Feidian 6 Ultra tops a three-model Feidian 6 family that also includes the Feidian 6 Elite and the training-oriented Feidian 6 Challenger. Against the Elite, RTINGS measured a taller stack and slightly more weight, with less foam under the forefoot.
Its midsole is a single foam, Li-Ning's Super Boom PEBA, with no secondary layer. The distinguishing feature is the carbon plate: a two-tier, asymmetric design that leaves a void beneath the midfoot, in contrast to the spoon-shaped plate of the Elite. RTINGS notes that this gap is a weak point for midfoot landings. The upper is a sock-like construction with a fully gusseted tongue and flat laces, and there is no wide fitting. The shoe is built primarily for marathon racing, according to RTINGS, and weighs 207 g in a men's UK 8.5.

The reviews in briefRTINGS' testers David Marquez, Robin Bonneau Patry and Yannick Khong found the Li-Ning Feidian 6 Ultra a light, very bouncy marathon racer with a smooth rocker, but its midfoot void and narrow heel made landings wobbly. Supwell's tester felt it firmer than the Elite yet stable, praising its protective foam and roomy toe box.

Fit
True to size
RTINGS found it true to size with a comfortable forefoot for a racer, but a tight arch and a narrow heel that may bother wider feet.
