Extended Product Information

FAQs

Are these shoes suitable for running?

These are optimized for tennis and lateral movement. While they offer cushioning, they lack the specific heel-to-toe drop and gait guidance required for long-distance running.

How do I determine my size?

These trainers follow standard UK adult sizing. It is recommended to measure your foot in the evening when it is at its largest and compare it to the brand's specific size chart.

Can I remove the insoles to use custom orthotics?

Yes, the insoles are generally removable, allowing you to insert your preferred orthotic supports if necessary.

What is the primary benefit of the K-Frame?

The K-Frame provides rigid lateral support, which locks the foot in place during side-to-side movements to prevent injury and improve agility.

How often should I replace these shoes?

For competitive players, tennis shoes typically last for 50-70 hours of court time before the foam midsole begins to lose its responsive properties.

Troubleshooting

Feeling discomfort or pressure in the forefoot

Ensure the laces are not pulled too tightly over the instep; re-adjust for a balanced tension that allows the TPU K-Frame to work without pinching.

Visible wear on the outsole after short-term use

Check your movement patterns; aggressive sliding on abrasive surfaces will accelerate wear. Rotate shoes to allow the foam to decompress and recover.

Pros and Cons

Pros

  • High-energy return from the Hyper Foam midsole
  • Excellent forefoot stability provided by the TPU K-Frame
  • Lightweight build prevents heavy, sluggish movement
  • Durable upper material holds up against court abrasion
  • Co-designed with pro athlete insights for competitive performance

Cons

  • Specifically tuned for performance, may be less comfortable for casual all-day wear
  • Requires proper sizing for maximum stability performance
  • Limited to tennis and high-intensity movement applications

Setup, Compatibility & Care

To ensure optimal performance, ensure the size chosen provides a snug fit around the arch without pinching the toes. For care, wipe down the exterior with a damp cloth after every court session to prevent dust and clay from clogging the breathable pores of the Duraprint upper. Avoid machine washing or drying, as high heat can degrade the integrity of the Hyper Foam midsole and structural adhesives. Allow the shoes to air dry naturally in a shaded, well-ventilated area.
