adidas Futurecraft 4D - Black - Striped - UK 8

The 4D midsole is created using digital light synthesis, a process that uses light, oxygen, and liquid resin to form a lattice structure. This structure is precisely engineered based on 17 years of athlete data to provide advanced cushioning and support.

The Primeknit upper offers a flexible, sock-like fit that can accommodate various foot shapes. However, individuals with very wide feet may wish to try them on to ensure optimal comfort.

Refer to the adidas sizing chart for accurate measurements. The sock-like fit means the shoe should feel snug but not restrictive.

No, machine washing is not recommended. Hand-wash only using mild soap and water, and air dry.

The reflective three-stripes are a design element that also enhances visibility in low-light conditions, making them safer for outdoor activities during dawn, dusk, or night.

The 4D midsole is designed for durability. With proper care and normal usage, the cushioning properties are expected to last for the lifespan of the shoe.

Yes, the 'Core Black' 2021 version is a reissue of the original 2018 Adidas Futurecraft 4D model, featuring updated materials and construction for contemporary comfort and style.

Loosen the laces and re-tie them, ensuring the Primeknit upper has room to expand. If still uncomfortable, consider if the size is correct or if the break-in period is needed.

This is normal for the 4D technology. Wear the shoes for short periods initially to allow them to conform to your foot and for the midsole to adapt.

Use a soft-bristled brush or a cotton swab with a small amount of mild soap and water to carefully clean the intricate areas of the midsole.

Avoid harsh cleaning chemicals or excessive abrasion on the stripes, as this can damage the reflective material over time.
