Steve “The FOOTMAN” – Shoe review
Shoes to save your legs while doing high mileage MIZUNO Sky 3
“The softness at first heel strike and the smooth transition to toe-off made the Sky one of my favourite shoes to do the bulk of my training…. I recommend this shoe to anyone wanting to increase their mileage without hammering their legs. ” Steve
History of midsoles:
Running shoes have been constantly evolving over the decades since the first running boom in the 1970s. While the early focus seemed to be on stability features the innovation of EVA foam midsoles was perhaps an even more significant design factor.
The first midsoles were made from flat EVA sheets that were cut out and glued together with the uppers and outsole. Later came injection moulded insoles that had more consistent density, were lighter and could be shaped into different shapes to cradle the foot. At the same time, there were new cushioning compounds inserted into the midsole like Nike Air, Asics Gel and Brooks Hydroflow.
While many inserts had a negative impact on the stability the Mizuno Wave plate technology was able to contribute to both stability and cushioning. This was possible by changing the wave plate frequency and height while the plate increased the amount of cushioning gained from the midsole below the plate.
In recent years companies have been mixing in ever new cushioning compounds that have taken EVA to another level. The result has been softer, lighter shoes with a smoother ride. The practice of blocking foot action has given way to enhancing foot function.
The Mizuno Wave Sky and Sky Waveknit is a high mileage super cushioned shoe with a very smooth ride. While this is a neutral shoe it still has significant torsional stability along the long axis of the foot. This makes it ideal for runners with mild to moderate pronation as well as supinators. This is a shoe that can easily accommodate orthotics as it is wider and more supportive through the midfoot giving the runner a firm base on the ground.
With the Mizuno Wave Sky and Sky Waveknit, Mizuno has transformed their wave technology with XPOP PU foam and Mizuno Foam Wave. The PU Foam is an insert inside the midsole of a softer more responsive compound. There is a small section under the shoe with this material that is exposed so you can feel the difference. Mizuno has some even more amazing compounds in the pipeline to be rolled out over the next year. The Foam Wave maintains the Wave design while removing the thermoplastic plate. They combine to create an all-new running experience that makes you feel like you’re floating while running. It also features an AeroHug fit that delivers comfortable security. With the knitted version this firm fit is enhanced by a superior ability to conform around your individual bumps and lumps.

The Low Down:
I was really surprised by the comfort offered by the original Wave Sky a few years ago. It seemed to be a departure from the firm shoes that Mizuno had been offering during the minimalist running phase. The softness at first heel strike and the smooth transition to toe-off made the Sky one of my favourite shoes to do the bulk of my training. With the latest offering, they have been able to capture that same great feel while somehow enhancing the softness at contact. With the change from the Wave Plate to the Foam Wave, it has made this shoe lighter and more flexible without losing the responsiveness and protection of the previous versions of the Mizuno Sky. I recommend this shoe to anyone wanting to increase their mileage without hammering their legs.
