Nike ACG Mountain Fly 2 Low Gore-Tex - Grey - UK 13

Yes, the Nike ACG Mountain Fly 2 Low Gore-Tex features a Gore-Tex membrane, which is designed to be fully waterproof and windproof while still allowing some breathability. This means your feet should stay dry in rain, puddles, and wet conditions.

Brush off loose dirt when dry. For tougher spots, use a damp cloth with a mild soap. Avoid harsh chemicals or machine washing. Always air dry naturally away from direct heat.

These shoes are ideal for a range of activities including hiking, light trekking, camping, exploring urban environments, and general outdoor use where weather protection and durability are important.

The Gore-Tex membrane itself remains waterproof. However, the external Durable Water Repellent (DWR) coating on the fabric may wear off over time. If water stops beading on the surface, you can reapply a Gore-Tex approved DWR treatment spray to maintain the fabric's water-shedding properties.

While the Gore-Tex membrane provides waterproof protection from snow and slush, these shoes are not specifically insulated for extreme cold. They can be worn in mild winter conditions, but for very cold temperatures, additional thermal socks or insulated footwear might be more appropriate.

ACG stands for 'All Conditions Gear'. It is a Nike sub-brand dedicated to creating products that are durable, protective, and comfortable for use in various outdoor environments and weather conditions.

First, check for any visible damage to the shoe's upper. Ensure your socks are not absorbing sweat and transferring moisture from inside the shoe. Also, verify that water isn't entering from the top opening (e.g., through pant legs in heavy rain). If the DWR coating on the outside has worn off, water can 'wet out' the outer fabric, which can feel cold and clammy, even if the Gore-Tex membrane itself isn't leaking. Reapply a DWR treatment if needed.

Ensure you have the correct size and width; refer to standard UK adult sizing. Check your lacing — sometimes adjusting the tightness can significantly improve comfort. Allow for a short break-in period as the materials may soften and adapt to your foot over time. Consider trying different types of socks, as their thickness and material can impact fit and comfort.

Inspect the outsole tread for any embedded debris like small stones or mud that could be reducing grip. Clean the sole thoroughly. Wear on the outsole can also reduce traction over time, especially in high-wear areas. Ensure the surface you are on is appropriate for the shoe's intended use; no shoe can offer perfect grip on all surfaces (e.g., wet ice).

After each use, allow your shoes to air out completely. Remove insoles if possible to facilitate drying. Ensure you are wearing appropriate moisture-wicking socks. For persistent odor, you can use shoe deodorizers or a mild solution of water and vinegar to clean the interior, then allow to air dry completely.
