What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
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 praise
- Full-length foam midsole feels smoother and more cushioned than the previous version
- Wide, plush toe box and true-to-size fit
- Medial and lateral sidewalls give noticeable but non-intrusive stability
Reviewers push back
- Heavier than many neutral or lightly-supportive trainers
- Stability feels milder than the previous generation, with less arch pressure
- Not suited to faster workouts or long race efforts
Reviewers agree the Structure 26 is a comfortable, mild-to-moderate stability shoe with a redesigned foam midsole and better upper padding, though it's heavier and softer than some expect from a stability model.
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
One reviewer calls the arch support diminished versus the prior model, while another (a podiatrist) found the stability features precisely placed and highly effective for his ankle instability
