Salomon Aero Flow GRVL - Trainers - UK 9.5

Yes, the Energy Foam midsole provides ample cushioning and responsiveness, making them suitable for marathon distances, especially for runners who appreciate a dynamic feel and versatile grip.

Clean the GORE-TEX membrane using a damp cloth and mild soap. Avoid aggressive cleaning agents. Ensure the shoes are air-dried thoroughly.

The QuickLACE system is integrated and not designed for replacement with traditional laces. However, replacement QuickLACE cords are available if the original becomes damaged.

The primary advantage is the optimized outsole with adaptable grip and the GORE-TEX membrane, allowing for confident and dry transitions across mixed terrains like asphalt, gravel, and trails, which road-only shoes typically cannot handle as effectively.

Energy Foam is designed to offer a combination of softness for comfort and responsiveness for energy return, providing a more dynamic and less 'mushy' feel compared to some standard EVA cushioning systems.

While they offer good grip and comfort for walking on trails, they are primarily designed as running trainers. For very rugged or technical hiking, dedicated hiking boots might offer more ankle support and durability.

Adjust the tension by pulling or releasing the lace lock. Ensure the excess lace is tucked into the pocket to prevent it from loosening during activity.

Check for holes or damage in the membrane. Ensure the tongue gusset is properly sealed to prevent water ingress from the top. Consider if the shoes have been submerged for extended periods, which can overwhelm the membrane.

Ensure the outsole is clean from mud or debris. For extremely slippery conditions, be aware that specialized footwear might be necessary. The grip is optimized for a balance of surfaces.

Allow for a break-in period. The Energy Foam midsole and overall construction will become more flexible with use.
