If it is white or bright running shoes, it is best to wear shorts, light-colored jeans or sweatpants.
If it is dark running shoes, as long as it is leisure, sports and jeans, K is white.
If it is a red running shoe, with gray narrow-leg pants, the color contrast is strong and eye-catching. Black plaid sweater is full of geometry, handsome and stylish. Red sneakers are well matched, which adds a lot of color to the overall shape. Paired with red running shoes, sneakers and hemmed jeans is the simplest and most neat. The main reason is that the collocation of red sports shoes should reflect youthful vitality.
In short, in addition to deliberately expressing the color of the color, the general contrast should not be too large. Loose pants, not low-waisted, jeans or casual K, can be added with a strap. With a nice T-shirt, it can be big neckline, sky blue, pink, golden orange.
