Nike ACG Mountain Fly 2 Low Gore-Tex - Grey - UK 4

Gore-Tex is a waterproof, breathable fabric membrane. In these shoes, it means your feet will stay dry from external moisture (rain, puddles) while allowing perspiration vapor to escape, helping to keep your feet comfortable.

While durable and supportive, these shoes are primarily designed for walking, urban exploration, and light trail use, not dedicated running. For serious running, especially on trails, specialized running shoes would offer better cushioning and flexibility.

Brush off loose dirt, then use a damp cloth with mild soap to wipe the surface. Rinse with clean water and air dry at room temperature away from direct heat. Avoid machine washing or drying.

The Gore-Tex provides waterproofing and a degree of wind resistance. For warmth in cold weather, it's recommended to pair them with appropriate thermal socks. They are not specifically insulated for extreme cold.

ACG stands for All Conditions Gear. It's a Nike sub-brand focused on creating footwear and apparel designed for outdoor activities and variable weather conditions, emphasizing durability, protection, and performance.

These shoes are listed in UK adult sizes. It's generally recommended to try them on to ensure a comfortable fit, especially considering the type of socks you typically wear. If unsure, measure your foot length and compare it to Nike's size chart. Info needed: [Link to Nike's official size guide if available].

Ensure pants are not tucked inside the shoe, allowing water to wick down into the shoe. Check for physical damage to the Gore-Tex membrane (e.g., punctures). Also, consider if it's sweat buildup; Gore-Tex is waterproof but breathability has limits, especially in humid conditions or with thick socks.

Inspect the outsole for excessive wear or embedded debris. Clean the treads thoroughly. If worn, the rubber may have lost some traction. For extremely slippery surfaces like ice, specialized footwear or traction aids may be required as these shoes are designed for general trail and urban grip.

Ensure you are wearing appropriate socks; very thick socks can alter the fit. Try re-lacing the shoes, ensuring even tension without over-tightening. If discomfort persists, consider if the size is correct for your feet, noting that foot size can change throughout the day.
