What reviewers say?
Distilled from the video reviewers — the score, what they praise, where they push back.
Reviewers praise
- Wave plate provides a distinct and effective medial stability mechanism that guides overpronating feet through the gait cycle
- Firmer, responsive ride that feels snappy and energetic at pace
- Lighter than previous versions of the shoe, with a slightly wider forefoot
Reviewers push back
- Firm, structured feel is not well-suited to runners who prefer soft or flexible shoes
- High heel-to-toe drop may irritate forefoot conditions and requires adaptation
- Some runners find the upper and midfoot area bulky and stiff, especially at non-standard paces
A firm, responsive stability trainer with a Wave plate that most reviewers praise for its structured support and improved ride, though runners used to soft, flexible shoes may find it stiff.
Reviewers disagree on versatility: the podiatrist reviewer considers it suitable up to half-marathon distances at pace, while the Running Warehouse panel found it less comfortable outside a standard easy-to-moderate effort
