  • Mizuno’s love affair with entry level runners resonates in the Spark. It is a highly-functional shoe that offers oodles of comfort, plush cushioning, and a wide mix of color options for a very budget-friendly price. While it understandably does not many accessories, it works as a versatile trainer that can handle 10Ks to long-distance runs.
  • An AirMesh upper is a signature Mizuno feature that delivers maximum breathability. Recreational or serious runners never fail to appreciate the benefits of a well-ventilated shoe.
  • Another premium technology in the outsole is the X-10 carbon rubber. Placed in strategic areas, it provides proven durability with just enough traction for runners to feel confident on the road.

An average space in the heel to the forefoot summarizes the fit of the Mizuno Spark. This mostly favors a large number of runners. Plus, it has decent width and volume for those who want more room in the forefoot. Medium is the available width of this shoe. Sizing is standard with options 6 to 14 for the men’s and 4 to 11 for the women’s.


Like many of the trainers in Mizuno’s fold that is built for entry level runners, the outsole is a full-contact surface for stability and better transitions. There are signature flex grooves for added flexibility. Mizuno uses its patented X10 carbon rubber in high-wear areas to prolong the shoe’s lifespan. The X10 rubber is also used in some popular shoes like the Mizuno Wave Rider 22.


The midsole is very simple as it showcases a large chunk of premium-grade EVA for that plush cushioning. It is a midsole foam that is quite light with decent responsiveness and durability. The substantial foam gives that plush feel for recreational runners to enjoy their runs.


The renowned AirMesh gives the ultimate breathability in an upper design. This is clearly a good way to entice new runners to make the most of their runs because of the sweat-free and cool ride. As always, there are synthetic overlays that secure the foot and provide structure to the upper. The collar molds very well with the ankle bones and the heel for plush comfort and security.
