Salomon Aero Flow GRVL - Brown - UK 9.5

Yes, the Salomon Aero Flow GRVL trainers are suitable for marathon running due to their lightweight design and cushioning, especially if the course includes varied surfaces like roads and gravel paths.

While they offer versatility, they are primarily designed as running shoes. For dedicated hiking on rough or steep terrain, a more robust hiking shoe with enhanced ankle support and grip would be more appropriate.

Use a soft brush to remove dry dirt. For wet cleaning, use a damp cloth with cold water and mild soap. Avoid harsh chemicals. Always air dry away from direct heat.

The main advantage is their versatility, allowing runners to switch seamlessly between road and gravel terrains without compromising on comfort or performance.

The outsole is designed for durability and grip on both road and gravel. For extremely abrasive surfaces or prolonged use on rough terrain, wear may be accelerated compared to on smoother surfaces.

GRVL is an abbreviation for 'Gravel', indicating the shoe's capability to perform well on gravel surfaces in addition to roads.

The Salomon Aero Flow GRVL is not a waterproof shoe. It is designed for breathability and versatility across different conditions, but it does not offer a waterproof membrane.

Experiment with the tension on different parts of the lacing system. Try re-lacing the top eyelets first to ensure a snug heel lock, then adjust the midfoot tension.

The grip is optimized for dry to moderately damp conditions on road and gravel. For very wet or slippery surfaces, proceed with caution. Ensure the outsole is free of mud or debris.

Ensure the correct UK size is being used. Break in the shoes with shorter runs initially. Check for any foreign objects inside the shoe that might cause irritation.

The optiFOAM midsole is designed for durability, but cushioning can naturally decrease with extensive mileage. Consider replacing the shoes after approximately 300-500 miles (500-800 km) of use, depending on terrain and impact.
