Nike Air Force 1 Crater Flyknit Trainers - Grey - UK 6

No, the Flyknit upper is breathable and water-resistant to a degree, but not fully waterproof. They are not designed for use in heavy rain or wet conditions.

The Crater foam provides lightweight cushioning and a distinctive, modern aesthetic, contributing to the shoe's comfort and eco-friendly design.

Refer to the Nike sizing chart for UK shoe sizes. These trainers are designed for a snug fit due to the Flyknit upper, but should not feel overly restrictive.

These trainers are primarily designed for lifestyle and casual wear. While they offer good cushioning, they lack the specific support and features required for serious running.

Flyknit is a woven polyester yarn that offers a lighter, more breathable, and flexible fit compared to traditional leather, which tends to be more rigid and less breathable.

'Crater' refers to the Nike Grind rubber particles incorporated into the foam, giving the midsole its unique speckled appearance and contributing to its recycled content.

The Flyknit material will stretch slightly with wear. If they feel uncomfortably tight initially, try wearing them with thinner socks. Ensure you have the correct size by checking the UK sizing guide.

Clean the waffle pattern on the outsole with a brush to remove any embedded dirt or debris that may be affecting grip.

The Crater foam's speckled appearance is part of its design. For general cleaning, use a damp cloth. Significant discoloration may be permanent due to the material's nature.
