New Balance 520v9 Trainers - Blue - UK Size 4

While the Fresh Foam cushioning provides comfort for daily runs, the 520v9 is primarily designed as an everyday trainer. For marathon distances, consider shoes with more advanced support and cushioning specifically engineered for endurance.

Ensure there is about a thumb's width of space between your longest toe and the end of the shoe. The heel should feel snug but not tight, and the midfoot should offer a comfortable hold without pressure points.

Yes, the 520v9 trainers can be used for general gym activities due to their comfort and lightweight nature. However, for activities requiring significant lateral stability, such as weightlifting or cross-training, specialized gym shoes might be more appropriate.

Fresh Foam is New Balance's proprietary cushioning technology, made from a premium EVA foam. It is engineered to provide a soft, ultra-cushioned, and responsive feel, minimizing impact during each stride.

Use a soft brush with a mixture of mild soap and cool water to gently clean the mesh. Avoid soaking the shoes. Allow them to air dry completely away from heat.

No, the engineered mesh upper is designed for breathability, not waterproofing. They are not suitable for wet conditions or activities where your feet need to be kept dry.

Loosen the laces and ensure they are evenly distributed. If still uncomfortable, consider if the size is correct or if the shoes need a brief break-in period.

Ensure the laces are tied securely. Clean the outsole to remove any dirt or debris that might be hindering grip. If the issue persists on wet surfaces, be aware of the limitations of the tread pattern.

Ensure you are wearing appropriate athletic socks. Give your feet time to adjust to the cushioning and fit, especially if transitioning from different footwear. Try wearing them for shorter periods initially.
