Reebok Energen Trainers - Black/Grey - Size: 8.5

The Energen Speed trainers are designed for daily training and responsive rides. While they can be used for shorter race distances, they may not offer the maximum cushioning or support required for the demands of a full marathon compared to specialized marathon shoes.

The upper is primarily constructed from a breathable mesh material, with tonal synthetic overlays for support.

It is not recommended to machine wash these trainers. Cleaning with a damp cloth and mild soap is the preferred method to preserve the materials and structure.

These shoes are best suited for daily training runs, tempo runs, and general fitness running where a responsive and lightweight feel is desired.

Yes, the sizing provided is standard UK adult foot sizing.

The Energen series generally refers to Reebok footwear designed to provide energy return and a responsive feel for runners, focusing on efficiency and a lightweight experience.

The tonal synthetic overlays provide targeted support to key areas of the foot, helping to maintain stability and structure without adding significant weight.

Ensure you have the correct UK size. Try wearing them with your usual running socks to gauge fit. If still uncomfortable after a few wears, consider if they are the right model for your foot type or stride.

Check your running gait for any pronation or supination issues. Ensure you are using the shoes on appropriate surfaces (avoiding abrasive surfaces regularly).

Ensure the mesh is not clogged with dirt or debris. Check for any insoles that might be reducing airflow. For extreme heat, note that maximum breathability is subjective.
