Featherlight Lunarlon trainer — soft, simple and quick.
Built for tempo, daily, at a target pace of 6:30–8:45 /mi on road.
This model is no longer in production. The closest shoe you can buy today is Nike Rival Fly 4.
Nike tuned this midsole balanced (3/5 on our cushioning scale). Energy return is moderate — comfortable and predictable rather than bouncy. 24 mm of heel stack keeps you low and connected, with more ground feel than most current trainers. Combined, the ride reads as lively at 3/5 responsiveness.
There is no plate here. The midsole does all the work, so the shoe flexes naturally and stays versatile across paces — easier on the feet day to day, but without the snap of a plated shoe when you want to roll.
A 8 mm drop is the mainstream middle — familiar to almost anyone coming from a standard trainer. The geometry is fairly traditional and flat, so the shoe follows your foot rather than steering it. The forefoot flexes easily, so the shoe adapts to slower, shorter strides. Support is light — neutral, with a mildly steady platform.
The toe-box is standard width — comfortable for most feet without swimming. It fits true to size. Expect roughly 300 miles from the outsole, about $0.33 per mile at $100.
