Description
Flagship On super shoe for road racing and marathons. Represents a major leap in energy return and cushioning over previous On models. Widely recognized for its lively ride and race-focused design.
Delivers a soft, bouncy, and highly propulsive ride at fast paces. Narrow platform and minimal heel structure create a focused, aggressive feel but limit stability. Upper is airy and comfortable, though some lockdown issues persist. Ride is most rewarding for efficient, forefoot or midfoot strikers.
Best suited for experienced racers seeking maximum energy return and cushioning for marathons and shorter road races. Not recommended for heel strikers or those needing stability. Excels in hot conditions and fast efforts, but durability and stability trade-offs mean it should be reserved for race day and key workouts.
