FAQs

Are these shoes suitable for outdoor running?

Yes, they are suitable for road or pavement running, though they are not designed for muddy or highly technical trail terrain.

Can I use these for heavy powerlifting?

While the TPU cage adds support, these are trainers designed for all-around movement; dedicated lifters may prefer a flatter, less cushioned sole for heavy squatting.

How should I clean the outsole knobs?

Use a medium-bristle brush to dislodge any small pebbles or dirt trapped between the knobs on the outsole.

Is the sizing true to size?

Yes, the Under Armour Phantom X generally follows standard sizing, providing a snug, secure fit thanks to the knit upper.

Can I replace the insoles?

Yes, the internal liners can be removed to accommodate custom orthotics if required.

Troubleshooting

Foot slipping during lateral movements

Tighten the midfoot laces slightly and ensure the heel is fully seated in the back of the shoe.

Knit upper feels loose after extended use

Wash the knit material with a slightly damp cloth to help the fibers shrink back slightly and air dry completely.

Pros and Cons

Pros

  • Lightweight construction prevents foot fatigue during extended wear
  • Highly responsive cushioning provides a bouncy, comfortable ride
  • Breathable upper material helps regulate foot temperature
  • Stable midfoot support suitable for various gym activities

Cons

  • Standard lace closure may require frequent adjustments for specific foot shapes
  • Sole design is primarily optimized for flat surfaces
  • All-black aesthetic may show dust and dirt more clearly than other colorways

Setup, Compatibility & Care

To ensure optimal performance, ensure you are wearing the correct athletic socks that align with the knit construction of the upper. For cleaning, remove loose dirt by tapping the soles together and use a soft brush to remove debris from the knobbed outsole. Wipe the knit upper with a damp cloth and mild soap; avoid submerging the shoes in water or using a washing machine, as high heat and heavy agitation can compromise the adhesive bonds and foam integrity. Air dry in a cool, shaded area away from direct heat sources like radiators.
