Nike ACG Mountain Fly 2 Low Gore-Tex - Grey - UK 7.5

Yes, the Nike ACG Mountain Fly 2 Low features a Gore-Tex membrane, which is designed to be fully waterproof and breathable, keeping your feet dry in wet conditions while allowing perspiration to escape.

These shoes are suitable for light to moderate hiking, trail walking, and urban exploration. Their low-cut design offers good flexibility and grip but less ankle support than traditional high-top hiking boots, making them less ideal for very rugged terrain or heavy loads.

Brush off loose dirt, then use lukewarm water and a mild soap with a soft brush. Rinse thoroughly and air dry completely at room temperature, away from direct heat. Avoid machine washing.

For best performance, wear moisture-wicking socks made from synthetic materials or merino wool. These materials help pull moisture away from your skin, enhancing the shoes' breathability and preventing discomfort. Avoid cotton socks, which retain moisture.

Footwear sizing can vary. It's generally recommended to try them on to ensure the best fit, especially considering the importance of a snug yet comfortable fit for hiking. Refer to Nike's official sizing guide if purchasing online.

While the Gore-Tex membrane offers wind and water protection, these shoes are not insulated. For very cold temperatures, you might need to pair them with thicker, insulated socks or consider footwear specifically designed for cold weather.

First, check your socks; cotton socks absorb moisture and can make your feet feel wet even if the shoes are waterproof. Ensure the top of the shoe isn't submerged, allowing water to enter over the cuff. If the outer fabric is saturated (not beading water), the DWR coating may need reapplying to allow the Gore-Tex membrane to breathe effectively.

Inspect the sole for accumulated dirt, mud, or debris that might be reducing traction. Clean the outsole thoroughly. Also, check for excessive wear on the tread pattern, which could indicate it's time for replacement, especially if used frequently on abrasive surfaces.

Verify you have the correct size and width. An improper fit is the most common cause of discomfort. Experiment with different lacing techniques to find one that provides a secure yet comfortable fit without pressure points. Ensure you are wearing appropriate socks for your activity.

This is often caused by moisture and bacteria. Ensure the shoes are thoroughly dried after each use, especially if they got wet inside. You can use odor-absorbing inserts or spray a shoe deodorizer. For persistent odor, a gentle wash as per care instructions, followed by complete drying, may help.
