FAQs

Are these shoes waterproof?

The Nike ACG ZoomX Ultrafly Trail SP is designed for breathability and moisture management, but they are not categorized as fully waterproof.

Can I use these for road running?

While technically possible, the outsole lugs are designed for soft and uneven trail surfaces; using them on asphalt will cause the outsole to wear down prematurely.

How should I clean mud off the mesh?

Let the mud dry completely first, then use a soft brush to knock it off. Follow up with a damp cloth if necessary.

Do these provide arch support?

The shoe provides a stable platform with moderate arch support designed for neutral trail runners.

Is the sizing true to standard Nike sizes?

Yes, they generally follow standard Nike sizing, though the performance fit is slightly more secure/snug than casual footwear.

Troubleshooting

Feeling discomfort during the first few miles

Ensure the laces are tensioned evenly across the midfoot; the secure fit might require a brief break-in period to contour to your foot shape.

Reduced traction on wet surfaces

Check the outsole for caked-on mud or debris trapped between lugs, as this will significantly reduce grip performance.

Setup, Compatibility & Care

To ensure the longevity of your Nike ACG trail shoes, proper care is essential. Always loosen the laces fully before taking the shoes off to maintain the integrity of the heel counter. If the shoes become muddy after a hike, allow them to air dry away from direct heat sources, such as radiators, which can degrade the foam cushioning. Once dry, brush off loose debris with a soft-bristled brush. For deeper cleaning, use mild soap and a damp cloth; avoid submerging them in a washing machine, as this can damage the performance adhesives and technical fabrics.
