Nike Dunk Low Gtx Trainers - Brown - UK 6.5

Gtx stands for GORE-TEX, a specialized membrane that is fully waterproof, windproof, and breathable. It's designed to keep your feet dry and comfortable by preventing water from entering while allowing perspiration to escape.

These trainers are highly water-resistant and suitable for light to moderate rain and damp conditions. However, for extremely heavy downpours or submerging your feet in deep water, water may still enter over the collar of the shoe. They are not designed for deep puddles or heavy snow.

Wipe off surface dirt with a damp cloth. For tougher stains, use a GORE-TEX approved footwear cleaner and a soft brush. Always air dry at room temperature; avoid machine washing or using direct heat sources like radiators or dryers.

Over time, the DWR (Durable Water Repellent) finish on the outer material may wear off. If water stops beading up, you can apply a GORE-TEX approved DWR spray or wash-in treatment after cleaning to restore this surface repellency.

Yes, GORE-TEX material is designed to be breathable, allowing moisture vapor from your feet to escape, which helps regulate temperature and keep your feet comfortable. However, they may feel slightly less breathable than a non-GORE-TEX mesh sneaker in very hot weather.

Generally, Nike Dunk Lows tend to run true to size for most individuals. However, fit can vary slightly between models and personal foot shape. If you have wider feet, you might consider trying a half size up. It's always best to try them on if possible or refer to Nike's official size guide.

While durable and comfortable, these are fashion trainers designed for casual wear and everyday activities, not for high-performance sports or running. They lack the specialized cushioning and support required for athletic training.

Ensure water is not entering over the top of the shoe (e.g., from deep puddles or heavy rain without appropriate leg coverings). Check the shoe's surface for any cuts or abrasions that might have compromised the GORE-TEX membrane. Clean the outer material; accumulated dirt can sometimes compromise the DWR treatment.

New GORE-TEX shoes can sometimes feel slightly stiffer than standard trainers initially. Allow for a break-in period of a few wears. Ensure you are wearing appropriate socks; moisture-wicking socks are recommended for GORE-TEX footwear. Verify you have the correct size; fit is crucial for comfort and performance.

This indicates that the DWR (Durable Water Repellent) treatment on the outer fabric has worn off. This is normal with use. Clean the shoes thoroughly, then apply a GORE-TEX approved DWR spray or wash-in treatment to restore the water-shedding capabilities. The GORE-TEX membrane inside will still be waterproof, but the outer layer will absorb water without the DWR.
