Updates to Mizuno Wave Stream

  • The Mizuno Wave Stream is a running shoe that’s designed for those who have neutral pronation. This road-companion has a sporty design to cater to those who want a performance-centric look to their running apparel. It also employs a breathable yet seamless façade to exude a smooth and irritation-free construction.
  • A full-length U4ic foam serves as the primary cushioning unit of this neutral shoe. It is sustained by the bouncy yet impact-attenuating U4icX wedge and the supportive Parallel Wave unit. On the outsole is a rubber compound that is highly resistant to abrasion.

Size and fit

The Mizuno Wave Stream was constructed using the standard running shoe length. Runners are welcome to get a pair that follows their regular sizing preferences. When it comes to width, the available options are D – Medium for men and B – Medium for women. This shoe’s foot-shaped last mimics the curvature of the human foot.


X10 is a technology that is comprised of carbon rubber, which is a durable and anti-abrasive compound. It is liberally placed on the external pad, shielding the rest of the platform from wear-and-tear. This outsole material is found in some popular Mizuno shoes like the Wave Inspire 15.

Flex grooves are shallow depressions on the forefoot section responsible for heightening the flexibility of the sole unit. These patterns are helpful in encouraging a well-rounded toe-off.

The SmoothRide engineering is composed of a convex-shaped external platform that helps the foot to transition smoothly from the heel to the toe.


U4ic is a full-length cushioning unit that runs the entire length of the Mizuno Wave Stream. The purpose of this foam is to provide lightweight support and impact protection. Moreover, it is touted to be 30% lighter than Mizuno’s AP+ midsole.

The U4icX wedge is placed in the back portion of the platform. This add-on further heightens protection against the impact forces generated by the foot-strike. Also, it is lightweight and bouncy.

Mizuno’s exclusive Parallel Wave technology is placed between the U4ic and U4icX pieces. This thermoplastic add-on is meant to keep the foot steady as it rests on the platform, saving it from wobbling during the run. Also, it leads the foot towards a smooth transition through the gait cycle.

A midsole ventilation system called Mizuno Intercool makes sure to disperse heat from the interior chamber while allowing environmental air to circulate.


AIRmesh serves as the external fabric of the Mizuno Wave Stream. This material is thin, yet securely constructed. It has small ventilation holes that accommodate air into the foot-chamber.

Synthetic overlays are directly printed onto the façade. These thin prints are intended to reinforce the structure of the upper, keeping its form intact. They also aim to help the fabrics and the lacing system when it comes to locking the foot in place.

The Mizuno logo is emblazoned on the sides, also acting as securing overlays.

The tongue and collar are padded. These parts of the upper are designed to cushion the topmost dimensions of the foot like the instep, the ankles, and the Achilles tendon. They are also meant to prevent accidental shoe removals.

The DynamotionFit technology is made up of a stretchy mesh on the middle part that adapts to the shape and movement capacity of the foot. During the run, the foot bends and swells. It is the job of this feature to accommodate the dynamic changes to the figure and frame of the foot, thereby proving an impression that the in-shoe experience is secure yet custom-built.
