adidas Ultra Boost 1.0 DNA Trainers - White - UK 8.5

The Ultra Boost 1.0 DNA is designed for comfort and daily wear, with good cushioning for general running. For competitive marathon running, specialized marathon shoes might offer more specific features.

Gently clean the PRIMEKNIT upper with a soft brush or cloth using mild soap and cool water. Avoid harsh scrubbing or machine washing/drying.

The 'DNA' designation typically indicates that the shoe reinterprets iconic elements of its predecessors, often focusing on lifestyle comfort and familiar aesthetics.

The yarn made from Parley Ocean Plastic is integrated into the upper, contributing to a more sustainable manufacturing process by repurposing plastic waste, without compromising the shoe's comfort or performance.

The Continental™ rubber outsole provides good traction, but the PRIMEKNIT upper is not waterproof. While they can handle light moisture, they are not ideal for heavy rain or wet conditions.

The 1.0 DNA series often focuses on bringing back classic designs with modern updates and a particular emphasis on lifestyle applications, differing from more performance-oriented or updated versions.

Generally, adidas Ultra Boost shoes are considered true to size for most customers. However, individual fit can vary, and it's always recommended to check size charts and consider trying them on if possible.

Try a double knot or consider replacing laces with those that offer better grip.

Ensure laces are properly adjusted for a snug but not overly tight fit. Check that the shoe size is correct; an improper fit can cause discomfort.

While the Continental™ rubber offers good grip, performance can vary on extremely wet or slick surfaces. Ensure the outsole is clean from debris.

Adjust the lacing system to provide more support. The nature of PRIMEKNIT is to be flexible; tightening the laces can compensate for perceived looseness.
