adidas Supernova Rs3 - Trainers - Blue - UK 8

These trainers are designed for everyday wear and offer good cushioning, but they are not specialized for competitive marathon running. For such events, consider footwear specifically engineered for performance running.

The trainers are true-to-size. Ensure there is a thumb's width of space between your longest toe and the end of the shoe. Your heel should feel secure without slipping.

It is not recommended to machine wash these trainers. Hand washing with a damp cloth and mild soap is the preferred method to preserve their material and structure.

DREAMSTRIKE+ is an adidas cushioning technology designed to provide a comfortable and responsive feel, enhancing energy return during wear.

The trainers are not waterproof. They are designed with breathable materials which allow airflow but do not provide protection against significant water ingress.

The rubber outsole is designed for durability and provides reliable traction for everyday use. Regular cleaning and avoidance of excessive wear will maximize its lifespan.

This is normal for new trainers. Wear them for short periods initially to allow them to break in and conform to your foot shape.

Ensure you have selected the correct size. If the issue persists, consider using aftermarket insoles designed for additional arch support, compatible with the trainer's standard profile.

Check the outsole for embedded debris and clean it with water. If the tread is significantly worn down, it may be time to consider replacement.
