In production · road · Tempo / Race day · $145
Loud, light triathlon-friendly speed trainer with quick-entry upload.
Built for tempo, race day, at a target pace of 6:15–8:15 /mi on road.
Asics tuned this midsole balanced (3/5 on our cushioning scale). Energy return is above average: the midsole rebounds well without feeling unstable. 32 mm of heel stack is the modern daily-trainer sweet spot — enough foam for long miles without losing contact with the road. 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 low 5 mm drop encourages a midfoot landing and keeps the ankle working through a fuller range. 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 300 miles from the outsole, about $0.48 per mile at $145.
