Discontinued · road · Race day / Tempo · $115
Snow-named Japanese racer update to the S4.
Built for race day, tempo, at a target pace of 5:30–7:30 /mi on road.
This model is no longer in production. The closest shoe you can buy today is Asics Hyper Speed 4.
Asics tuned this midsole balanced (3/5 on our cushioning scale). Energy return is above average: the midsole rebounds well without feeling unstable. 28 mm of heel stack keeps you low and connected, with more ground feel than most current trainers. Combined, the ride reads as snappy at 4/5 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 7 mm drop is the mainstream middle — familiar to almost anyone coming from a standard trainer. The rocker is moderate — enough curve to smooth the roll-through without dictating your footstrike. Forefoot flex is middle of the road. It is a neutral platform with no built-in correction.
The toe-box is standard width — comfortable for most feet without swimming. It fits true to size. Expect roughly 250 miles from the outsole, about $0.46 per mile at $115.
