Nike ACG Mountain Fly 2 Low Gore-Tex - Grey - UK 9

While the GORE-TEX provides waterproofing, these shoes are not insulated. They are suitable for wet conditions in mild to cool temperatures but may not provide sufficient warmth for very cold, snowy, or icy winter conditions.

No, machine washing is not recommended as it can damage the GORE-TEX membrane, adhesives, and overall structure of the shoe. Please follow the hand-cleaning instructions outlined in the care section.

For optimal performance, especially in wet or active conditions, we recommend wearing moisture-wicking synthetic or merino wool socks. Avoid cotton socks, as they retain moisture and can lead to discomfort and blisters.

No, the sole on the Nike ACG Mountain Fly 2 Low Gore-Tex is not designed to be replaceable. The shoe is constructed as a single unit for durability and performance.

The GORE-TEX membrane should prevent water from entering the shoe. If you notice water consistently penetrating the shoe in wet conditions, first ensure the outer fabric's DWR is functional (water should bead up, not soak in). If the issue persists and there's no visible damage, the membrane may be compromised.

Yes, their versatile design and comfortable fit make them suitable for everyday casual wear, especially in urban environments or during unpredictable weather. The low profile design also contributes to their adaptability.

First, ensure your socks are not cotton, which retains moisture. Opt for synthetic or wool hiking socks. Secondly, check that the laces are tightened correctly to prevent water ingress from the ankle opening. Finally, inspect the shoe's upper for any visible damage or tears that might compromise the waterproof membrane. If the outer fabric is 'wetting out' (absorbing water instead of beading), consider reapplying a DWR treatment.

Inspect the stopper mechanism for any trapped debris or damage. Ensure the laces are threaded correctly through all eyelets and the stopper. Sometimes, a firm pull and release of the stopper can reset its grip. If the issue persists, contact customer support.

The sole may have accumulated dirt, mud, or fine particles. Clean the rubber sole thoroughly with water and a stiff brush to remove any embedded debris from the lugs. If the tread is significantly worn down, traction will naturally decrease, indicating the sole may be nearing the end of its effective lifespan.

Ensure you have the correct shoe size and are wearing appropriate socks. Break in new shoes gradually with shorter walks before attempting longer excursions. Consider replacing the standard insole with an aftermarket orthotic if you require additional arch support or cushioning.
