What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Lighter than the previous version, noticeably so on the run
- Softer, more plush ride with increased stack height and smooth rocker geometry
- Roomier toe box and improved upper fit compared to earlier models, accommodating wider feet
Reviewers push back
- Significantly less responsive and less bouncy than predecessor models, disappointing fans of the earlier, livelier ride
- Upper breathability is below average; the dual-layer jacquard mesh restricts airflow
- Stability is milder than before — the H-frame and softer foam make it less corrective than the J-frame design, which may not suit moderate-to-severe overpronators
The Arahi 8 is a well-made mild stability daily trainer that is softer, lighter, and roomier than its predecessor, though it sacrifices the responsiveness and firmer stability that fans of earlier models valued.
Where reviewers split on Arahi 8: Reviewers disagree on the heel counter: one describes it as notably more flexible and softer, while another calls it fairly stiff and rigid
