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
- 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.
Where reviewers split on Adrenaline GTS 25: 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 Wave Inspire 21: 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
