Billie Eilish x Nike Air Force 1 High '07 SP - Brown - UK 7.5

They are constructed with recycled synthetic leather and feature Nike Grind outsoles, which are made from recycled manufacturing waste.

While comfortable for walking and casual wear, these are fashion-oriented sneakers and not designed for high-impact athletic activities like running.

The five straps can be adjusted individually to provide a customized and secure fit around your foot and ankle. Loosen or tighten each strap as needed.

The 'Mushroom' colorway refers to a specific shade of earthy brown that covers the entire shoe, creating a monochromatic and bold aesthetic.

While the synthetic leather offers some protection, these sneakers are not waterproof. It's advisable to avoid wearing them in heavy rain to protect the materials and maintain comfort.

The shoe should fit snugly but comfortably without any pressure points. Ensure your toes have a little room to move and the heel does not slip. Adjusting the straps can help fine-tune the fit.

Adjust the five straps for a more relaxed fit. Wear with thicker socks to test fit and consider if the size is appropriate for your foot width.

Gently wipe with a damp cloth and mild soap. For tougher stains, use a specialized sneaker cleaner suitable for synthetic leather, testing on an inconspicuous area first.

Ensure the Nike Grind outsoles are clean and free from debris. For added traction on very smooth surfaces, consider a spray-on traction enhancer designed for footwear.
