Appearance: The main body of this pair of Iuka2 has a gray-yellow visual effect, and it looks good on the feet. However, its appearance is a bit thicker and less speedy, giving it a low-lying and "stable" feeling. This pair is an environmentally friendly version. It uses environmentally friendly materials in a large area, including the midsole, upper, etc. The concept is still good. Static fit: The shoe last is wider than normal, but as a person with normally thin feet, I don’t feel empty when wearing it. The strap system of this version has been updated, and there is an extra strip on the outside to surround the shoe body.
