Nike ACG ZoomX Ultrafly Trainers - White - Orange - UK 9

The ACG ZoomX Ultrafly is designed for breathability and performance on trails; they are not marketed as fully waterproof.

While wearable on roads, the tread and cushioning are optimized for trails, which may lead to faster wear of the outsole if used primarily on concrete.

Use a soft brush with mild soap and cold water to gently scrub away stains, then air dry in a shaded, well-ventilated area.

These trainers are neutral shoes. If you require significant stability support for overpronation, consult a professional for custom orthotic compatibility.

ZoomX foam is engineered to be Nike's lightest and most responsive cushioning, providing maximum energy return for increased efficiency.

Nike sizing is generally consistent across performance models, but always refer to your specific UK size measurement for the best fit.

Ensure the laces are tensioned correctly across the midfoot and consider a different lacing pattern to relieve pressure points.

Check the collar and tongue area for debris ingress after every run and consider wearing gaiters if running on particularly sandy or rocky trails.

Allow the ZoomX foam at least 24 hours of rest between intensive training sessions to allow the material to recover its shape.
