FAQs

Are these boots suitable for artificial grass?

These are designed for Firm Ground (FG). While they may work on some artificial surfaces, they are optimized for natural grass; using them on aggressive artificial turf may lead to premature wear.

How should I clean the Speedskin upper?

Wipe the surface with a soft, damp cloth. Avoid submerging the boots in water or using harsh chemicals.

Does the carbon heel lock make the boot stiff?

The carbon heel lock is designed for structural stability and lockdown, but the PRIMEKNIT collar ensures the overall fit remains comfortable and adaptive.

Do these boots run true to size?

The X Speedportal.1 generally fits true to size, but the snug, foot-hugging nature of the upper may feel tighter than traditional leather boots.

What is the primary benefit of the extra forefoot studs?

The extra studs provide enhanced traction during the toe-off phase, allowing for more explosive acceleration from a standing start.

Troubleshooting

Difficulty getting the boot on

Ensure the PRIMEKNIT collar is fully stretched before insertion; use a shoehorn if necessary to protect the heel structure.

Studs collecting excessive grass or dirt

Use a specialized boot cleaning brush to clear the gaps between studs after every match to maintain traction.

Feeling of slipping inside the boot

Verify that the lacing is tightened across the midfoot support cage rather than just at the top of the boot.

Pros and Cons

Pros

  • Extremely lightweight construction for maximum speed
  • Excellent lockdown and stability provided by the carbon heel lock
  • Optimized traction on firm ground surfaces
  • Snug, comfortable fit due to the PRIMEKNIT collar

Cons

  • Not intended for use on soft ground or excessively wet surfaces
  • Requires a break-in period for the synthetic Speedskin material
  • Specific design limits versatility across different pitch types

Setup, Compatibility & Care

To ensure the best fit, ensure the laces are adjusted through the midfoot support system before your first session. These boots are specifically rated for Firm Ground (FG) surfaces. To maintain the life of the boots, remove loose mud after every game using a soft brush. Wipe the Speedskin upper with a damp cloth and mild soap; avoid using aggressive cleaning agents that could degrade the synthetic surface. Store them in a cool, dry place out of direct sunlight to prevent the materials from drying out or losing their elasticity.
