Reebok - Viva Speed Trainers - Grey/Silver - UK 12

The Reebok Viva Speed trainers are designed for daily mileage and responsive running. While they offer good cushioning and energy return, for ultra-marathon distances, a shoe with more specialized, long-distance cushioning might be preferred.

These trainers are optimized for running. For gym workouts that involve a lot of lateral movement or heavy lifting, a cross-training shoe would provide better stability and support.

Ensure there is about a thumb's width of space between your longest toe and the end of the shoe. Your heel should feel secure without slipping.

The lifespan of cushioning depends on usage frequency, intensity, and running surface. For most runners, the optimal performance of the cushioning is typically within 300-500 miles.

No, the mesh upper is designed for breathability and is not waterproof. They are best suited for dry conditions. For wet weather, consider waterproof running shoes.

The wave profile is engineered to provide enhanced impact absorption and a smoother transition from heel strike to toe-off, contributing to both comfort and responsiveness.

Ensure you are wearing appropriate running socks. If the issue persists, consider trying a different size or lacing technique.

The midsole cushioning may take a few runs to break in. If the feel doesn't improve, the shoes may have reached the end of their lifespan for optimal performance.

Check the outsole for wear or debris. Ensure you are running on appropriate surfaces. If the issue persists on dry, clean surfaces, the tread may be worn down.
