Bottom line

Mizuno introduces a rather functional shoe that relies mainly on a dual-density foam set up in the midsole as its highlight. The synchronization of the midsole foam provides excellent support, protection, durability, and responsiveness. With the Synchro MX runners get a 12mm heel drop trainer that has good arch support and light enough for long-distance runs.

  • Mizuno introduces a new mix of its midsole foam technologies to provide runners with a durable, responsive, and resilient cushioning in a lightweight package. Aptly, called Synchro MX, the shoe synchronizes several midsole technologies to produce their maximum effects.
  • Mizuno staples like the AirMesh for exceptional breathability and the sturdy X-10 carbon rubber are located in the upper and the outsole, respectively. Fans of Mizuno get a regular dose of the best benefits of these two technologies.

The fit of the Synchro MX resembles that of a luxurious trainer. It has spacious room from the heel to the forefoot. Runners who love long and luxurious ride will love this type of fit while those with flat or inflexible feet can have more than enough wiggle room for their feet. Medium is the offered weight of this shoe. Sizes run true in the men’s 7 to 15 and the women’s 4 to 11.


The full-length rubber outsole delivers stability and helps with the efficient transition. Mizuno’s X10 rubber covers a large portion of the outsole for exceptional durability and moderate traction. Other road running shoes like the Mizuno Inspire 15 also features the same outsole material.

There are flex grooves in the heel and the forefoot as part of the SmoothRide technology and increased flexibility.


The midsole is where Mizuno packs the technology in the Synchro MX. It is also here where the shoe gets its name as the technologies work together for the best effect. This shoe uses a dual-density set up where the upper foam is firmer for enhanced stability and a better platform for takeoff while the lower foam features the softer U4ic-X foam for responsive cushioning. Mizuno uses more of the latter in the forefoot and heel areas to give the shoe a plush and responsive ride. This set up is synchronized by the use of the AP+ for even more durability and bounce back features. Instead of the Wave technology, Mizuno utilizes the SR Touch, another foam-based cushioning in the heel to absorb shock.


The AirMesh upper never fails to provide maximum breathability. There are synthetic overlays providing lightweight support and structure as well. Part of the overlays extends to the heel to secure the area. The seamless construction of the upper creates an irritation-free interior. A traditional lace-up closure keeps the fit tied and secured from start to finish.
