Good to know

  • The Mizuno Wave Catalyst 2 is ready to provide quality performance with a touch of support for those who need it. This new iteration offers a more flexible upper unit, with extra breathable mesh on the forefoot for reinforcement and airiness. A mix of stitched and fused overlays help in delivering a snug yet secure coverage.
  • The midsole unit of this Mizuno running shoe makes use of the popular Mizuno Wave thermal plastic unit that runs from the heel to the mid-foot section. It cushions the landings and sets the foot up for a well-rounded transition through the gait cycle. Full-length cushioning is handled by the U4ic, a lightweight foam unit that’s able to carry the foot responsibly through the running session. The Fan Wave dynamically supports the mid-foot, thus preventing over-pronation.
  • Two rubber compounds are used in the outsole unit of the Mizuno Wave Catalyst 2. They work in tandem in order to provide protection and traction for the runner. They also shield the mid-sole materials from the potentially abrasive nature of the asphalt, preserving the structure of the platform and extending its lifespan.

Regular measurements were used in the making of the Mizuno Wave Catalyst 2. In terms of the sizing scheme, it mostly follows the standard preferences of runners. It accommodates those with medium sized feet because its width-profile is medium. The semi-curved shape of this shoe mimics the natural shape of the human foot.

X10 is made from durable carbon rubber. It protects the mid-sole from wear and tear. It also responsibly delivers traction, which helps in achieving surface control. Blown Rubber in the forefoot section adds a bit more cushioning on top of its capability to provide traction. It’s soft and responsive, so it won’t make the front section of the platform stiff or unwieldy.

The U4ic mid-sole foam is made from high-quality and lightweight materials that deliver soft and responsive cushioning. Running the entire length of the shoe, it ensures that the foot is receiving agreeable cushioning throughout the gait cycle. A thermal plastic unit called Wave is placed in the mid-sole. Running from the heel to the mid-foot section, it gives additional cushioning, as well as springiness with each step. The Fan Wave makes the platform more stable, thus allowing the foot to stay in a neutral gait when taking each step. The SmoothRide is a set of grooves that allow the foot to move more smoothly with every step. Its gender-specific design makes it agreeable to the foot-dimensions of men and women. The OrthoLite Sock Liner offers additional cushioning to the immediate underfoot. It has anti-microbial and anti-moisture properties, which make the interior environment healthy and dry.

AIRmesh is the material that’s used for the upper unit of the Mizuno Wave Catalyst 2. It offers soft and breathable coverage to the foot of the wearer. The forefoot section of the shoe features open mesh. This stretchable material heightens breathability while also maintaining a secure fit. A mix of stitched and fused overlays makes the upper secure. They don’t cause the façade to look bulky or uneven. The Dynamotion Fit delivers an optimum fit by utilizing a stretchy material in the forefoot, as well as a more robust collar construction for added sturdiness.
