The upper material is made of silk like nylon, which is not only more resistant to dirt but also easy to handle. The most important thing is that this bright black color has a more organic and windy atmosphere. In terms of color matching, it is more concise and lively, with a pure black upper, tongue, and laces, and a pure white rubber midsole. The simple and classic color combination is not difficult to match. The biggest highlight is that the heel of the shoe comes with a detachable waist pack, and there are pockets on both sides of the shoe.
