Reebok Energen Speed Trainers - White/Black, Size: 6.5 UK

While the FuelFoam offers cushioning, the Energen Speed is primarily designed for faster, shorter-distance running. For marathons, runners may prefer models with more extensive cushioning and support for endurance.

These trainers are optimized for running. For gym workouts or cross-training that involves lateral movements, a shoe with more lateral stability might be more appropriate.

You should have about a thumb's width of space between your longest toe and the end of the shoe. The heel should feel secure without slipping, and there should be no pinching or excessive pressure points.

The FuelFoam is engineered for responsiveness and durability for its intended use. Like all cushioning foams, its performance may gradually decrease after hundreds of miles of use.

No, the mesh upper is designed for breathability and is not waterproof. They are suitable for running in dry to lightly wet conditions.

The seamless wavy overlays provide a secure, locked-in fit while reducing potential friction points, which helps to prevent blisters and chafing during high-velocity running.

Try the trainers with different thickness socks. If the issue persists, consider a different size or width, as fit can vary slightly between individuals and even manufacturing batches.

Ensure laces are tied correctly to avoid pressure points. Break in the shoes gradually with shorter runs before attempting longer distances.

The outsole is designed for optimal performance on dry to moderately wet roads. Be cautious on very slick surfaces, as specialized trail or all-weather shoes may offer superior grip.

The seamless overlays are designed for a locked-in fit. If it feels excessively tight, ensure your foot is positioned correctly within the shoe and the laces are not overtightened.
