Nike Shox R4 - Black - UK 9

Nike Shox technology features a system of resilient, flexible columns in the heel. These columns compress under impact to absorb shock and then spring back, providing responsive cushioning and energy return. This mechanical design is engineered for superior impact absorption and comfort.

The Nike Shox R4 is primarily designed for casual wear, walking, and light activities. While the Shox cushioning provides comfort for short jogs, it is not optimized for high-performance or long-distance running, which typically requires lighter, more flexible footwear with different stability features.

You can clean your Shox R4 by gently wiping the synthetic and textile upper with a damp cloth and mild soap. For the rubber outsole, use a brush to remove dirt. Always air dry your shoes at room temperature, away from direct heat or sunlight.

The Nike Shox R4 features a durable upper constructed from a combination of synthetic and textile materials, a foam midsole for added comfort, and a rubber outsole for traction. The core cushioning system utilizes Nike Shox technology.

The Shox R4 includes a standard foam midsole and the Shox cushioning system, which contributes to overall foot comfort and support. For individuals requiring specific arch support, custom insoles can be used, provided they fit comfortably within the shoe.

Nike Shox R4 typically runs true to size for most individuals. However, fit can vary slightly based on foot shape. It's generally recommended to choose your usual Nike size. If unsure, consider trying them on or consulting a size chart.

This is normal for new footwear, especially with structured soles. Wear them for short periods initially to allow the materials to break in and conform to your feet. The Shox columns may need a few wears to become fully flexible.

A squeak can sometimes occur if moisture gets between the insole and the shoe's base. Try removing the insole, cleaning both surfaces, ensuring they are completely dry, and then reinserting. If the squeak persists from the outsole, it might indicate wear, but usually, it's a minor friction point.

Ensure you wear breathable socks. After each use, allow the shoes to air out completely. You can also use shoe deodorizers, cedar inserts, or a small amount of baking soda inside the shoes (placed in a sock or pouch) to absorb moisture and odor.

For synthetic and textile uppers, use a mild soap and water solution with a soft cloth or brush. Gently scrub the affected area. For stubborn stains, specialized sneaker cleaning kits can be effective. Always test cleaners on an inconspicuous area first.
