Consensus Summary
The Mizuno Wave Sky 9 offers a max-cushioned ride with a 6mm heel drop, making it a significant shift from its predecessor, the Wave Sky 8. While it provides a plush feel underfoot, reviewers note that the cushioning can feel surprisingly firm at slower paces, which may not suit all runners. The shoe features a 44mm stack height, contributing to stability issues, particularly for those accustomed to lower-profile shoes. The energy return is decent but lacks the responsiveness needed for tempo runs. Additionally, the narrow toe box may not accommodate wider feet comfortably, and the overall weight is higher than previous models, which could affect speed work. This shoe is better suited for recovery runs or long, slow distances rather than fast-paced training.
Pros
- ✓47.1% forefoot energy return at faster paces
- ✓44mm stack height for max cushioning
- ✓Standard fit with snug midfoot support
- ✓Non-stretch woven mesh upper for durability
- ✓Recommended wide version for better fit
Cons
- ✕Narrow toe box unsuitable for wide feet
- ✕Heavier than previous model at 295g
- ✕Stability issues from high stack height
- ✕Ride feels firm at slower paces
- ✕Not ideal for tempo or speed work
