Salomon AERO FLOW GRVL Trainers - White/Black - UK 9

The AERO FLOW GRVL offers good cushioning and comfort for a range of distances, including marathons, especially if your route includes varied terrain. However, they are primarily designed for mixed-terrain versatility rather than being a specialized long-distance road racing shoe.

Use a soft brush to remove loose mud. For stubborn dirt, wipe the shoes with a damp cloth. Avoid high-pressure washing or harsh detergents, as these can damage the materials and the Gore-Tex membrane's effectiveness.

Yes, replacement QuickLACE cords and toggles are typically available from Salomon or specialist outdoor retailers. Instructions for replacement are usually provided with the replacement parts.

The Energy Foam midsole provides a dual benefit: it offers significant cushioning to absorb impact on harder surfaces, and it delivers a reactive bounce, making your stride feel more energetic and efficient.

Thanks to the Gore-Tex membrane, the trainers offer waterproof protection, keeping your feet dry from external moisture like rain, puddles, and wet ground. Ensure the shoe collar is adequately sealed to prevent water ingress from the top.

The outsole is designed for an adaptable grip on asphalt, gravel, and light trails. While it offers good traction, it may not provide the aggressive, specialized grip required for very technical or rocky mountain trails compared to dedicated trail running shoes.

It is recommended to consult a sizing guide or try the shoes on in person if possible. For online purchases, check the brand's specific sizing chart. Many runners find it beneficial to have a little extra room in running shoes, especially for longer distances. The UK size 9 is listed for this specific variant.

Ensure the QuickLACE toggle is fully engaged. Check the lace ends for fraying, which can cause slippage. Re-tie the knot if the toggle mechanism is worn.

Check for obvious points of water entry, such as around the ankle collar or if the shoes have been submerged. Ensure the Gore-Tex membrane itself has not been compromised by damage. Clean the shoes to remove any dirt that might be affecting membrane performance.

Confirm you are on a surface the outsole is designed for (road, gravel, light trail). Clean the outsole tread of mud or debris, as this can significantly impact grip. For extremely slick conditions, reduced speed and careful foot placement are advised.

Adjust the tightness of the QuickLACE system. Ensure you are wearing appropriate socks. If the rubbing persists, the shoe size or shape may not be ideal for your foot. Try different lacing techniques.
