Footwear Reviews, Shoe Review
Introduction:
The Mizuno Wave Sky has been a solid offering within Mizuno's footwear lineup. The latest iteration, the Wave Sky 9, boasts a complete redesign from top to bottom, and I’m here for it. If you're seeking a maximum cushion trainer that provides a sensation of weightless comfort, this shoe is an ideal choice. Continue reading for my review of the Wave Sky 9, designed to make your runs feel as if you're floating on clouds.
The Upper: Soar with the Mizuno Wave Sky 9
-
Lacing System: The Wave Sky 9 features a traditional lacing system. While not revolutionary, it provides a solid lockdown. An additional eyelet is provided for those who prefer using a runner's loop for an even more secure fit.
-
Tongue: The tongue is well-padded and partially gusseted, ensuring it remains comfortably in place throughout your runs.
-
Heel: A plush heel counter contributes to a secure and stable heel fit.
-
Overall Feel: The upper is constructed from a stretchy, woven material that offers both a secure fit and excellent breathability.
The Underfoot: Cloud-Like Comfort?
The Mizuno Wave Sky has long been Mizuno's flagship max cushion neutral shoe, and version 9 undoubtedly excels in this category. Its dual-layered midsole incorporates nitrogen-infused MIZUNO ENERZY NXT foam for softness and responsiveness, complemented by a layer of MIZUNO ENERZY foam to enhance stability. The innovative FOAM WAVE technology integrates these foams into a unique wave-shaped structure.
After testing it out this past week, including multiple runs and casual wear, here are some key observations:
-
The shoe delivers a soft and bouncy sensation without compromising on stability.
-
Its rockered geometry facilitates a smooth and effortless transition through each stride.
-
The upper while strechty can feel a little snug, and I would recommend wearing a ½ size up.
Overall, the Mizuno Wave Sky 9 provides a plush underfoot experience, making it perfect for easy daily miles, recovery runs, long runs, or even everyday wear (especially beneficial for individuals who spend long hours on their feet). When combined with its breathable and secure upper, this shoe stands out as an excellent option for those desiring a premium running experience. If you've worn previous versions, prepare for a pleasant surprise; the Wave Sky 9 offers enhanced cushioning and a more enjoyable ride. It truly feels like running on clouds.
Who is the Wave Sky 9 for?
I highly recommend this shoe for neutral runners seeking a shoe for:
-
Recovery runs
-
Easy-paced long runs
-
All-day wear
Additionally, this is an excellent shoe for walkers.
