Facts

  • A durable construction is part of the outstanding qualities of a trail running shoe. The Kien 3 from Mizuno was created to remain strong amidst different types of terrain. The upper unit uses a breathable material that doesn’t easily tear apart or get loose. Stitched-on and fused overlays deliver a secure fit that’s tuned to the preferences of the wearer.
  • The mid-sole unit of this running shoe makes use of a lightweight compound that is still able to provide exceptional cushioning throughout the running session. Its rebound capability also keeps the foot engaged and enabled to take each step. The Mizuno Wave Technology© causes the foot-landings to become smoother and less taxing to the runner because it absorbs impact shock.
  • Durable protection against wear and tear is a hallmark of a dependable outsole unit. The Mizuno Wave Kien 3 features a carbon rubber material that covers the entire surface area of the external sole unit. It keeps the platform safe from abrasion and the potentially deteriorating effects of continued use. The rubber is also responsible for surface traction, which is largely important when traversing the off-road paths.

Standard measurements were used for the sizing scheme of the Mizuno Wave Kien 3. Men and women are treated to a correct fit when they try this model out. The available width is medium. Those with medium sized feet are the ones who are going to acclimate well to this shoe. Its semi-curved shape follows the curvature of the human foot.


The X10 is a durable carbon rubber material that’s responsible for the protection of the rest of the sole unit. Wear and tear might damage the material, so it’s the X10’s job to stave off such concerns. It’s also capable of delivering sure traction on many types of surfaces. It doesn’t have very prominent gripping lugs, therefore allowing the Kien 3 to transition well between smooth and uneven ground. This outsole configuration is also used in some Mizuno shoes for running such as the Wave Creation 20 and Wave Rider 22.


The Mizuno Wave Kien 3 has the EL8 mid-sole, a compound that has a lightweight nature. It is able to deliver reliable cushioning at all times. It even has a rebound capability that returns energy to the foot of the runner in order to make each step more energized.

The Mizuno Wave Technology© features a unit in the rear of the mid-sole that’s meant to handle the impact shock during the foot-strike. This results in a more cushioned and comfortable feeling every time the foot lands on the ground.

A removable insole adds a bit more cushioning to the underfoot. It doesn’t have a stiff nature, so it won’t restrict the movement of the foot.


The AIRmesh is a breathable material that allows air to easily enter the shoe in order to keep the foot cool and dry. Though it has an open construction, it doesn’t tear off easily.

The Dynamotion Fit system uses a stretchable material as part of the upper unit. It allows the foot to move more naturally without feeling restricted by the upper.

Stitched-on and fused overlays help the upper fabrics of the Kien 3 when it comes to securing the foot and keeping the coverage as customizable as possible. Connected to the lacing system, they adapt to the tightening and loosening of the shoelaces.
