FAQs

Are these shoes suitable for long-distance running?

While the Phantom X provides excellent comfort, it is primarily designed as a trainer for gym work and daily wear, not as a specialized long-distance running shoe.

Can the insoles be removed?

Yes, the insoles are generally removable if you wish to use custom orthotics for personalized arch support.

How does the sizing run for this model?

The Phantom X generally fits true to size, but the knit upper offers a snug, sock-like feel, so ensure your standard size provides enough room for toe splay.

Is the material waterproof?

No, the engineered knit upper is designed for breathability and is not waterproof or water-resistant.

What is the purpose of the TPU cage?

The TPU cage reinforces the midfoot area to provide stability, preventing the foot from sliding within the shoe during lateral movements.

Troubleshooting

Knit upper appears dirty or stained

Use a soft-bristle brush and a mixture of water and mild soap to gently scrub the affected area, then air dry completely.

Reduced traction during workouts

Check the rubber outsole for trapped debris or pebbles caught in the knobbed texture and remove them to restore surface contact.

Feeling of discomfort across the midfoot

Loosen the laces around the TPU cage area to alleviate pressure points while maintaining the structural integrity of the fit.

Pros and Cons

Pros

  • Highly breathable knit material prevents overheating
  • Superior comfort provided by supercritical foam
  • Excellent lateral support from the TPU midfoot cage
  • Versatile design suitable for gym, casual, and walking use

Cons

  • Knobbed outsole may show wear faster on abrasive asphalt
  • Beige and black colorway requires frequent cleaning to maintain appearance
  • Not intended for heavy-duty off-road or trail running

Setup, Compatibility & Care

To ensure the longevity of your Phantom X trainers, follow these guidelines:

  1. Breaking In: The knit upper is designed to mold to your foot; allow for a few days of light walking to break in the foam and structural cages.
  2. Cleaning: Hand wash the shoes using a soft cloth, mild detergent, and lukewarm water. Avoid machine washing or drying, as high heat can compromise the foam cushioning and adhesive bonds.
  3. Storage: Keep your trainers in a cool, dry place away from direct sunlight, which can cause the materials to fade or become brittle over time.
  4. Lacing: Use the standard lace system to customize your fit; ensure the laces are snug but not tight enough to restrict circulation across the top of the foot.
