New Balance 520 V9 Trainers - Black - Size 8

The 520 V9 is designed for training and light running. While it provides excellent comfort, those focusing exclusively on high-mileage marathons may prefer specialized long-distance models.

No, machine washing can compromise the structural integrity of the cushioning foam and the adhesives used in the assembly.

The upper is made of polyester, which is breathable but not waterproof. It is best to avoid running in heavy rain.

The size follows the UK standard sizing convention, which is approximately equivalent to a US 9 or an EU 42.

Generally, it is recommended to replace trainers every 300 to 500 miles, or when you notice the foam no longer provides the same level of responsiveness.

Consider swapping the factory insole for a custom orthotic insert that matches your specific arch height.

Remove the insoles after training to air them out and use a shoe-specific deodorizing spray once the shoes are completely dry.

Check your lacing technique; try a 'runner's loop' or heel-lock lacing to keep the heel secure in the back of the shoe.
