Updates to Mizuno Wave Paradox 4

  • Not much has changed since the Wave Paradox 3. That version serves a blueprint for the development of the 4th iteration of the Paradox series. Minor tweaks have been made to its design, but the façade mainly stays the same.
  • But Mizuno has afforded some alterations, accommodating a few add-ons in the hopes of delivering more robust performance. The underfoot platform is slightly denser than that of the previous version, but the addition of a Strobel board and a sock liner compensates for that. The cushioning system treads the line between stiff and responsive.

Size and fit

The Mizuno Wave Paradox 4 is true to size. It follows the regular sizing preferences of runners. Regarding the width, the men’s version has D – Medium while the women’s version has B – Medium. The foot-shaped last allows this shoe to accommodate the natural curve of the human foot.


The outsole unit of the Mizuno Wave Paradox 4 features the X10, which is made of carbon rubber. This type of compound is sturdy. It can protect the rest of the midsole from the abrasive nature of the asphalt. It is also responsible for surface traction. This outsole material is also used in the Mizuno Paradox 5.


The chief material used in the midsole of the Mizuno Wave Paradox 4 is U4icX, which is a lightweight foam that’s designed to be responsive. It carries the foot through the gait cycle, making the transitions from the heel to the toe as smooth as possible.

Going from the heel to the midfoot area is the Mizuno Wave, a thermoplastic unit that adds a bit more cushioning to the foot. It’s elastic, so it doesn’t hinder the flexibility of the sole unit.

An Extended Wave Plate gives support to the midfoot and the forefoot areas. It heightens torsional rigidity, therefore strengthening the underfoot and keeping it from buckling during the running session.

A Double Fan Wave is placed in the medial section of the midfoot. It supports the arch, stabilizing it and preventing overpronation.

A gender-specific network of grooves accommodates the natural movement of the foot, therefore allowing a smooth and well-rounded step.

The Ortholite sock liner adds a bit more cushioning. It has anti-microbial and anti-moisture capabilities, thus ensuring a clean and odor-free in-shoe experience.


Open mesh is the primary material used in the upper of the Mizuno Wave Paradox 4. It doesn’t have noticeable pores; instead, it employs a more secure weaving technique to bolster durability and prevent debris-infiltration. It still aims to preserve breathability.

The Dynamotion Fit involves a stretchy material in the front and collar of this running shoe which moves along with the foot, delivering a secure yet seamless coverage.

Stitched overlays reinforce the fabrics. They also help in locking the foot in place, thus preventing wobbling and accidental shoe-removals.

The Strobel Last is made up of an U4icX board that’s stitched directly to the bottom edges of the upper. This construction heightens durability while delivering a consistent underfoot experience that doesn’t feel as if the mesh might detach from the sole unit at any time.
