Description
On’s first true super trainer, positioned as a maximalist daily and long-run shoe. Max-stack, dual-foam midsole with Speedboard plate. Reviewers consistently highlight stability, durability, and energetic ride.
Ride feels firm and stable, with lively rebound from PEBA foam and flexible plate. Wide base and rigid platform ensure excellent control, while weight and dense upper reduce agility and plushness. Smooth transitions and natural toe-off, but less engaging at faster paces.
Best for neutral runners seeking a stable, durable trainer for long runs and marathon training. Excels at steady daily mileage and moderate uptempo efforts, but less suited for those preferring soft cushioning or lightweight feel. Remains a strong choice for On loyalists prioritizing stability and durability.
