Nike ACG ZoomX Ultrafly Trainers - Yellow - Red - 8.5

The Nike ACG ZoomX Ultrafly is designed for breathability on the trail; they are not classified as waterproof.

While they can be used on roads, the tread pattern and foam composition are optimized for trail surfaces. Using them on roads will increase the wear rate of the outsole.

Use a soft brush to remove dried mud, then wipe with a cloth dampened with cool water and mild detergent. Do not machine wash.

They feature a neutral construction designed to provide stability for a wide range of foot types, though personal orthotics can be swapped in if needed.

These follow standard Nike men's sizing. If you frequently wear thick trail socks, some runners prefer to size up by a half size to accommodate foot swelling over long distances.

ACG stands for 'All Conditions Gear,' reflecting the design focus on performance in outdoor and rugged environments.

Ensure the laces are secured firmly, specifically using the 'runner's loop' to lock the heel in place.

Consider wearing gaiters, which are compatible with most trail shoes and prevent gravel from entering the collar.

Rotate between two pairs of running shoes to allow the foam to decompress and return to its original shape between runs.
