What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Guide rails on both medial and lateral sides deliver gentle, non-intrusive stability suited to overpronators and oversupinators alike
- Improved heel bevel and reduced drop create a noticeably smoother heel-to-toe transition compared to prior versions
- Padded, well-fitting upper with wider forefoot accommodates a broad range of foot shapes, including higher-volume feet
Reviewers push back
- Midsole foam is cushioned but dead — no energy return or bounce, feeling flat compared to newer-generation foams
- Warmer, less breathable upper becomes uncomfortable in hot conditions
- Forefoot firms up noticeably over longer distances, causing discomfort for some reviewers past seven or eight miles
A dependable, well-rounded stability daily trainer that rewards runners needing guided support, but offers a cushioned rather than energetic ride and runs warmer than many alternatives.
Reviewers praise
- Exceptional cushioning that balances softness with enough structure for long runs, achieved through FF Blast Plus Eco foam and PureGEL heel cushioning
- 4D Guidance System delivers stability in a natural, non-oppressive way that works for both overpronators and neutral runners
- Plush, well-padded upper with a secure heel pocket, gusseted tongue, and comfortable heel collar that rarely causes irritation
Reviewers push back
- The heel can feel clunky or cumbersome on tired legs or at slower paces, lacking a smooth rocker transition
- Breathability is moderate at best — the upper runs warm in hot conditions despite adequate ventilation
- The shoe is visually blocky and bulky; multiple reviewers note it sacrifices aesthetics for function
A well-built, highly cushioned stability shoe that earns broad praise for comfort and smooth support, with minor criticism for occasional clunkiness and a bulky appearance.
Reviewers disagree on whether the version-25 changes constitute a meaningful upgrade or merely a sideways step — one calls it 'side step rather than a huge leap forward' while others describe the heel transition improvement as the best in the line's history
On midsole softness: one reviewer felt the 31 is noticeably softer than the 30, while another was uncertain whether the change would feel meaningful underfoot
