adidas Ultra 4D Running Shoes - Core Black White - Trainers - UK 11.5

The 4D midsole is a 3D-printed lattice structure offering precisely engineered cushioning and energy return, unlike the uniform compression of traditional EVA foams. It provides support exactly where needed.

They are optimized for road running and daily training. While versatile, the advanced cushioning is best suited for paved surfaces rather than trail running.

Ensure there is a thumb's width of space between your longest toe and the end of the shoe. The heel should feel secure without slipping, and the midfoot should feel comfortably snug.

Yes, the comfort and supportive design make them suitable for casual wear and walking, in addition to running.

The upper is constructed from premium leather, offering durability and a classic aesthetic.

The 4D lattice structure is designed for durability and should maintain its responsive properties for a considerable mileage, often exceeding that of standard foam midsoles, though performance can gradually decrease with heavy use.

While this specific product is Core Black and White, the Ultra 4D series is available in various colorways across different product listings.

Ensure you have selected the correct UK size. Try wearing thinner socks. If the issue persists, consider alternative sizing or styles, as leather can have a break-in period.

Check for any debris or blockages within the 4D midsole structure, although this is rare. Ensure the shoes are not overly worn out. For new shoes, allow for a break-in period.

If wear is uneven, check your running gait. For general wear, ensure you are using the shoes on appropriate surfaces (avoiding abrasive terrains).

Verify the correct size and width. Ensure laces are tied appropriately – not too tight or too loose. Consider if the shoe's specific cushioning profile suits your running style.
