adidas Supernova Ris - Grey Five - Trainers - UK 6

The Supernova Ris Sn99 offers good cushioning for daily runs and training. For marathon distances, consider your personal comfort and the shoe's break-in period. They are well-suited for training runs leading up to a marathon.

Ensure there is about a thumb's width of space between your longest toe and the end of the shoe when standing. The fit should be snug but not constricting, with no slipping at the heel.

It is not recommended to machine wash these trainers. Hand washing with mild soap and water, followed by air drying, is the best method to preserve the materials and shape.

Different Supernova models may vary in cushioning technology, stability features, and upper materials. The 'Ris' designation often refers to a specific build within the Supernova line, focusing on a balance of responsiveness and support.

Generally, running shoes should be replaced every 300-500 miles (480-800 km) or when cushioning and support significantly diminish. Inspect your shoes regularly for signs of wear.

These trainers are primarily designed for road running and general training on firm surfaces. They can also handle light trails but may not offer optimal grip on highly technical terrain.

The trainers may require a break-in period. Wear them for short durations initially and gradually increase wear time. Ensure the lacing is adjusted correctly for your foot.

Check that the outsole is clean and free from debris. Ensure the shoes are laced securely. For very wet or slick surfaces, consider alternative footwear if maximum grip is paramount.

Avoid abrasive surfaces and conditions where the trainers might be easily damaged. Clean gently as per care instructions to prevent premature wear.
