To ensure the longevity and appearance of your Yeezy 450 Sneakers, care should always refer directly to the product label inside the shoe. Generally, for textile and rubber compositions, light spot cleaning with a damp cloth and mild cleaner is recommended for the upper.

Regular gentle cleaning will help maintain the textile and rubber components.
