Bottom line

The Synchro MD is an entry-level type of running shoe that Mizuno also designed for some gym activities. It offers a Spartan-like design where accessories are concerned, but offers tons of comfort, decent arch support, moderate cushioning, excellent breathability, and surprisingly very nice color options. As the shoe is very wallet-friendly, it should be a good choice for recreational joggers, middle of the pack runners, or those looking to take it easy on recovery days.

Good to know

  • Mizuno builds the Synchro series on a midsole design that offers guidance, cushioning, and effortless movement through the gait cycle. In the Synchro MD, the midsole is a wedge of slightly dense foam in the heel to the midfoot on the lateral side while the rest is made of the U4aicX for a softer and more responsive feel.
  • A very breathable AirMesh covers a large part of the upper to ensure a sweat-free and cool run. The mesh is just part of the DynamotionFit upper that frames the foot in support and comfort.
  • The Synchro MD outsole features the most durable rubber compound in Mizuno’s fold for maximum resistance against wear and tear.

The fit of the Synchro MD befits a shoe that is built for comfort during daily trainings. It holds the heel and the midfoot in place without being constrictive. The forefoot has a bit of extra room for those with flat, inflexible, or slightly wider feet to be comfortable. Runners with different types of feet should be able to get the most out of the shoe. The sizing is standard in this shoe as well.

The outsole is typical of a Mizuno road shoe. It is quite thick with X10 rubber for abrasion resistance in the heel and other parts while the rest is made of blown rubber for better traction. The Mizuno Prophecy 8 also uses the same outsole material and it is undeniably durable and grippy on varied surfaces.

There are flex grooves in the forefoot to enhance flexibility. A deep cut running from the heel to the forefoot helps with flexibility and smoothes the transition from landing to take-off.

The midsole of the Synchro MD is occupied mainly by the U4icX foam, which has above average responsiveness and cushioning. Making the run more stable is a small wedge of stiff EVA from the heel to the midfoot.

Mizuno’s DynamotionFit technology is at work in the upper of the Synchro MD. The whole upper works with the foot to provide a glove-like feel. An AirMesh with moderate-sized holes all over guarantee a very cool run. There are several stitched overlays, including the huge Mizuno logo, around the midfoot to secure the foot and provide support. Both the tongue and collar are well-padded for more comfort. A removable and plush insole adds comfort and cushioning.
