Since there is no box, the item will be shipped in recycled cardboard or thick plastic. ● Sole: The top midsole uses MIZUNO ENERZY LITE PLUS, which is lightweight and has excellent softness, allowing you to directly feel the cushioning on the soles of your feet. The bottom midsole uses MIZUNO ENERZY LITE, which has excellent resilience. The Smooth Speed Assist on the sole has been adjusted to a more elite runner-oriented angle, and is a speed-tuned specification that is more effective when running at high speeds compared to the previous model. The midfoot inner instep, which was a separate structure in the previous model, has been connected to increase the ground contact area, further supporting stability during running. ● Upper: Engineered mesh, which is lightweight and has excellent breathability, is used throughout. The sponge in the opening has been changed to a lighter design while ensuring a good fit.
