Good to know

  • The Mizuno Wave Sayonara 4 is a cool-looking running shoe that’s meant for runners who have a neutral running gait. It features a visually striking design, with vibrant color schemes that entertain but not distract. It has the conventional workings of a modern-day running shoe, but it doesn’t present its technologies in a boisterous manner; it looks simple yet it doesn’t shy away from being appealing to the eyes.
  • The upper unit of this Mizuno running shoe features fabrics that encourage breathability. The mesh materials have open constructions, which means that they are able to accommodate steady airflow through the shoe. With this design, the foot can experience coolness and dryness throughout the running session. Stitched-on overlays are used sparingly in this model, but they still give a snug & secure fit.
  • The mid-sole utilizes foam technologies that are reliable and long lasting. The entire platform itself has been optimized to deliver responsive cushioning and shock absorption. In conjunction with many Mizuno shoes, the Wave Sayonara 4 has the Mizuno Wave technology, which heightens cushioning, springiness and shock attenuation.

The Mizuno Wave Sayonara 4 has a standard running shoe length. The sizing schemes follow regular measurements. The available width for the men and women’s versions is medium. So, it is able to accommodate the runners who have medium sized feet. It has a semi-curved shape, which means that it follows the natural shape of the human foot.

The 4th version of the Mizuno Sayonara features the X10, a layer made from durable carbon rubber. It protects the rest of the sole unit from wear and tear. It doesn’t peel off easily, as well. This X10 outsole material is also used in the Mizuno Wave Creation 20.

Blown rubber is a more responsive rubber material. It’s adaptable to the movement of the foot. Placed in the forefoot section, it adds some more cushioning when tackling the toe-off phase, while also making the platform more pliable.

Flex grooves enhance the flexibility of the entire sole unit. The toe-off gets freedom from such a design because it’s the part of the gait cycle where the foot bends the most.

The U4ic is a lightweight mid-sole material that’s responsible for cushioning. It carries the foot and the weight of the runner with ease. It’s durable, so it won’t break down easily even after many uses.

The Smooth Ride is a design that permits natural movement. Basically, it allows the platform to take a rocking chair motion during each step, thus delivering a well-rounded and enabled running experience.

The Mizuno Wave is an elastic unit that runs from the heel to the mid-foot area of the mid-sole. It adds more cushioning, attenuates shock and delivers springiness to the ride.

The Ortholite Sock Liner gives antimicrobial and anti-moisture support, which is helpful when it comes to maintaining a clean and healthy environment for the foot.

The AIRmesh is the material in the heel area. The forefoot section has Open Mesh. These fabrics are breathable and they accommodate air into the foot-chamber. They ventilate the interior and keep the foot cool & dry.

Synthetic overlays are present in the Mizuno Wave Sayonara 4, but they’re not prominent. They do not make the façade bulky or stiff. Instead, they complement the design, while also making sure to deliver a snug and secure fit.
