About
What it is.
Positioned within Mizuno's running lineup as a max-cushion neutral trainer, the Wave Sky 9 is built around a nitrogen-infused Mizuno Enerzy NXT midsole paired with Foam Wave technology, aiming to combine plush shock absorption with underfoot stability for runners who log long miles or daily training without needing a stability shoe's guidance.
The Smooth Stretch Woven upper and gusseted tongue construction wrap the foot securely while staying breathable, and the X10 carbon rubber outsole is oriented toward durability and grip over repeated wear. It suits runners who want a dependable, ready-to-wear trainer from an established brand rather than something requiring adjustment or a break-in period.
The verdict
The Mizuno Wave Sky 9 delivers strong plush cushioning and pain relief that buyers consistently praise, though fit and forefoot durability concerns split opinions. At $169–$180, it suits runners seeking a proven shoe from an established brand, backed by a 4.8/5 rating across 333 reviews.

What owners single out
In their words
“I have plantar fasciitis and these shoes enable me to walk free from pain. They are so comfortable it’s like walking on air.”

“First time buying Mizuno shoes - normally go with Asics as they suit my wide feet. Gave these a go as the specs noted a Standard D width. Not as wide as expected...maybe my expectations were mismatched as I was hoping for a fit similar to a D-width Asics Kayano...The insole provides extra support and cushioning but reduces overall wiggle room and makes for a very tight fit.”
