The Mizuno Wave Sky 3 is an update to a series of neutral running shoes that are meant for the roads. The design moves away from the plastic Wave plates of the previous generation of Mizuno products. Now, it uses the Foam Wave construction to maintain a lightweight ride that doesn’t sacrifice smoothness of movement. The XPOP polyurethane (PU) serves as a core piece that is hugged by the cushioning units of the Foam Wave design.

The upper unit, though featuring the tried-and-true AIRmesh technology, frees up a significant portion of its surface to utilize printed overlays. The heel part still has a stitched-on layer, but it is of a defined purpose, and it doesn’t make the shoe look bulky.

The Mizuno Wave Sky 3 is constructed to be true-to-size. Runners are welcome to get a pair of these shoes with their usual sizing expectations in mind. Still, it is important to get a personal feel of the in-shoe experience before the actual purchasing process to avert any concerns about the aspect of the size.

When it comes to the sideways fit, this Mizuno running shoe features a form-welcoming upper and a semi-curved platform shape to ensure a snug, secure, yet accommodating hug. The uncluttered facade also contributes to the feeling of being unrestricted yet well-supported. The natural curvature and flexibility of the human foot have become the basis of the overall design.

X10 is the material that is used for the outsole unit of the Mizuno Wave Sky 3. This layer is made of carbon rubber, a famously durable compound that withstands the effects of constant use and exposure to the surfaces. It is also responsible for the traction capacity of the shoe, giving the foot a sensation of confidence and control over the surfaces.

While most Mizuno shoes have three forefoot flex grooves, the Wave Sky 3 has five shallow outsole channels to accentuate the smoothness of the heel-to-toe transitions. The toe-off phase of the gait cycle g the most from this design as it is the part of the step that involves the most foot flexion.

The outsole features a full ground contact configuration to ensure consistent and unwavering surface adhesion at all times. The midfoot portion even has rubber to maintain grip, even as the foot is merely transitioning through the step.

The midsole unit of this road running shoe is primarily made of the responsive yet slightly firm U4ic topsole and the spongy and impact-mitigating U4icX base. Both these elements work together to provide an energized performance during the running session. Idle standing also benefits from the luxurious two-layer configuration of the whole midsole unit. U4ic and U4icX are used in many of Mizuno’s series of shoes, including the long-running Wave Inspire line.

XPOP is a core piece that is placed at the center of the two-tech platform. The purpose of this polyurethane (PU) piece is to provide extra softness and responsiveness to the underfoot experience.

A fabric-topped insole is placed right above the primary cushioning feature. The purpose of this add-on is to provide a soft surface where the foot can rest and enjoy the overall ride. It can be removed or replaced with a new one if the runner wishes to do so.

The upper unit of the Mizuno Wave Sky 3 is made of AIRmesh. This technology is comprised of a multilayered fabric and an open-weave lattice that graces the exterior. The stretchy and form-welcoming nature of this material permits it to accommodate the natural shape and movement capacity of the foot. The open holes welcome environmental air into the foot-chamber, thus giving a ventilated in-shoe feel.

Printed overlays grace the sides and the eyestays. These synthetic elements buttress the structural integrity of the whole silhouette while also ensuring a secure wrap. The non-bulky construction of each layer prevents the product from being unwieldy, cumbersome, and bulky-looking.

The heel part has a stitched overlay to put some oomph to the hug of the materials.

The padded tongue and collar are charged with bringing some cushioning to the topmost portions of the foot, particularly the Achilles tendon, the ankles, and the bridge. These parts of the upper unit are also meant to avert in-shoe wobbling and accidental shoe removals.
