What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Generously padded, breathable upper with a locked-in heel fit that feels comfortable from the first run
- Stable, well-cushioned ride that suits neutral runners and mild overpronators equally
- Thick, soft outsole rubber delivers reliable grip on slick and wet surfaces
Reviewers push back
- DNA Loft V2 midsole returns little energy, making the shoe feel flat and uninspiring at faster paces
- Heavy construction due to extensive rubber outsole coverage
- Non-gusseted tongue allows lateral tongue movement during runs
A comfortable, reliable daily trainer with a plush upper and stable ride, let down by limited energy return and a high heel-to-toe drop that divides opinion.
Reviewers praise
- Power run plus midsole delivers soft, plush cushioning while retaining enough energy return for daily training
- Durable construction with xt900 rubber outsole and solid build quality that holds up over high mileage
- Comfortable fit with good lockdown and minimal break-in required
Reviewers push back
- Gained weight compared to the previous model, coming in heavier than some competing daily trainers
- Flat knit upper may feel warmer and less breathable than the previous engineered mesh in hot conditions
- Not designed for faster paces or tempo work despite being capable of handling varied runs
“I think this is a shoe that works with you it sort of disappears in a way I think that's really nice”
