LIGHTEN UP
Revolutionised for maximum protection and comfort, the Wave Sky 9 defines what it means to Float on your run. Perfect for long, easy runs and recovery runs when you want maximum comfort and protection. Available in Standard and Wide widths.
Fit Advice - The woven upper hugs the foot securely and does taper towards the forefoot. We recommend selecting your normal size, but if you want more forefoot room, select a half size up.

"I can see why this is called wave sky because it's feels like you're walking on waves of clouds. I initially tried this in when I had a foot full of corns and I couldn't feel them while wearing these so I bought them and loved them!"
"Comfortable and light"
"Suprisingly a fantastic Workshoe i work in sales im on my feet all day & these are fantastic so much so when i come home i dont wanna take them off"
"Quite a good shoe. Have stayed clear of Mizuno in he past as their 2E’s have been on the narrow side. These fit quite well though so pleasantly surprised. Comfortable as well. Only time will tell regarding durability."
"Overall very comfortable shoe, just be aware the sole is extremely chunky, I mean ridiculously thick, it doesn't show in the photos. It's kind of ugly but function over beauty imo."
"I am disappointed as they seem to be much more narrow across the footbed so my normal size is too small. Dissatisfied"
"Sole - doesn't last any where as long as the earlier models - wears out after about 175 km. Earlier models, sole lasted to 400, cushioning would wear out slightly earlier"
"The cushioning is not as good as the 5/6/7/8. They provided much more cushion for health strike runners. With the changes in 9, should I now switch to a different shoe?"
"Very different sizing and shape to the Wave Sky 8, not as much rebound. Not for me."
"I'm an ultra-long-distance runner, and I've been using the Wave Sky series of shoes for the last eight years. I've started running in the latest Wave Sky 9, and there are some improvements over the 8. The new rocker design means I'm running with less foot pain from bursitis, and noticeably less fatigue - both of which are big gains for me. The internal fabric gusset has been moved back as well, making it easier to fit Engo patches, which is another win. However, the shoe cut is too small in the mid-foot region and far too small in the toe box. This is causing me to suffer severe blisters in places that I've never blistered before. The blisters now take weeks to heal after a long run, and I'm at risk of losing several toenails from each ultra-marathon. This is despite going up half a size, as recommended, fitting Engo patches to the key rubbing points, and strapping using Mefix tape - under the supervision of a podiatrist who is also a long-distance runner! As my podiatrist said, I have a narrow foot for my size - so I'm wondering how other runners are in any way coping with this shoe over longer distances? I'm guessing they are being forced to choose another rocker super shoe from a different company. With just some minor tweaks, this shoe could go from good to astonishing. Currently, it's a 7/10 from me - while I look for an alternative."
