  • The mesh material used for the Wave Kien 2 from Mizuno has a more open construction than the one used for the original Wave Kien. Even the tongue is able to provide breathability on top of its capability to cover the top area of the foot comfortably.
  • Contrary to the design of its predecessor, this version utilizes more stitching and layered-in overlays. It’s there to deliver responsible security while also maintaining the overall structure of the upper unit.
  • The sole unit’s construction is more robust this time around. It has been strengthened and optimized to handle the unpredictable terrain found in the great outdoors. A thicker outsole unit is also used for this model as it greatly delivers long-lasting protection and trail-specific actions, such as traction.
  • The Mizuno Wave technology offers additional cushioning and stability to assist the heel and mid-foot in assuming a more neutral position when running and when standing idly. It also gives protection against impact.

The Mizuno Wave Kien 2 is true to its size. It comes in a variety of sizes that adhere to the specific preferences of runners. It has a medium width when it comes to its heel and mid-foot, though its forefoot area has a slightly wider surface to allow the toes to spread naturally. It’s semi-curved shape accommodates the natural curvature of the human foot, thus making the fit more agreeable.

The outsole unit makes use of a high quality rubber compound. Coined as the X10, this layer uses carbon rubber, which is capable of resisting wear and tear while supplementing traction over rough surfaces. It’s like a sticky shield that protects the sole unit from abrasion while holding onto the various surfaces responsibly.

The outsole has x-shaped gripping lugs, which are able to provide grip when it comes to traversing all sorts of trail conditions. Uphill and downhill treks are safer, and running over wet surfaces are much more responsive. It doesn’t let the runner succumb to accidental slips.

The Mizuno Wave technology is a separate part that’s inserted in the mid-sole. Running from the heel to the mid-foot area, it adds more cushioning and gives lateral & medial stability to those who want to have a more balanced platform. It is also able to absorb impact shock when landing the foot on the ground, particularly during heel striking.

The U4ic or the ‘euphoric’ mid-sole gives lightweight yet plush cushioning for runners. It’s a responsive foam that makes each step smoother and more agreeable.

The SR Touch is a cushioning compound that’s added to the rear section of the shoe. It’s a resilient material that causes easy bounce-back when landing the foot on the ground. It works well with the Wave tech in delivering a smoother ride.

The upper unit makes use of the AIRmesh. This main layer hugs the foot well and delivers breathable and comfortable coverage that lasts. It has a more open construction, so air can constantly enter the shoe and keep the foot cool & dry. The upper of the shoe is as breathable as the Wave Kien 3.

A reflective coating is added to the sides, forefoot and heel. It improves visibility of the product and the runner when it comes to nighttime running. It’s a safety measure, but it’s also a good way to increase the shoe’s overall aesthetic appeal.

The overlays have been stitched to the sides and heel of the Mizuno Wave Kien 2. They maintain the structural integrity of this shoe, but they also assist the upper fabrics in hugging the foot comfortably. Working with the lacing system, the overlays make the fit more customizable.
