adidas Yeezy Boost 380 - Trainers - Black - UK 4

The Yeezy Boost 380 'Onyx Non-Reflective' is designed as a lifestyle sneaker for comfort and everyday wear. While it offers cushioning, it is not optimized for high-impact running activities.

Refer to the size chart provided by adidas or the retailer. These trainers generally fit true to size, but the Primeknit upper offers a flexible fit.

It is not recommended to machine wash these trainers, as it can damage the materials and affect the Boost cushioning. Hand cleaning is the preferred method.

The 'Onyx Non-Reflective' version lacks the reflective threads found in its counterpart, offering a more subdued aesthetic for everyday wear.

The outsole is constructed for durability and stability for regular, everyday use on urban surfaces. It is not intended for extreme terrain or aggressive sports.

The upper is made from adidas' Primeknit material, known for its breathability, flexibility, and sock-like fit.

Ensure the correct size has been selected. The Primeknit upper may require a short break-in period. Loosen the laces before putting them on.

This can occasionally happen with darker dyed materials. It is recommended to wear darker socks or allow the shoes to air out thoroughly before initial wear.

Use a dedicated sneaker cleaning kit or a soft-bristled brush with a mixture of mild soap and water. For stubborn marks, consider professional cleaning.

While Boost technology is durable, prolonged intense use can gradually affect cushioning. Regular care and avoiding extreme conditions can help prolong performance.
