FAQs

Are these shoes suitable for hard courts?

These shoes are specifically designed for clay courts. While they can be worn on hard courts, the tread pattern may wear down faster, and the grip and performance characteristics are optimized for clay surfaces.

How do I clean the Duraprint upper?

You can clean the Duraprint upper with a damp cloth. For tougher stains, use a mild soap and water solution, then wipe clean with a damp cloth. Always air dry.

What is the main advantage of the K-Frame structure?

The TPU K-Frame structure under the forefoot provides exceptional stability, allowing for sharp, agile movements and confident directional changes, which is crucial on slippery clay courts.

How does the Hyper Foam midsole benefit performance?

The Hyper Foam midsole offers superior energy return and cushioning. This helps reduce impact on the joints during play and provides a more responsive feel, aiding in quick reactions and powerful movements.

What is the expected lifespan of these shoes on clay courts?

Lifespan depends on playing frequency and intensity. With proper care and use on the intended surface, the durable materials are designed for competitive play. Regular cleaning and air drying will help maximize their life.

Can these shoes be used for other sports besides tennis?

These shoes are highly specialized for tennis, particularly on clay courts. Their design focuses on the specific demands of tennis movements, so they are not recommended for other sports.

What size UK foot does this specific variant fit?

This particular variant is listed as fitting a UK size 13 foot.

Troubleshooting

Excessive clay buildup affecting grip

Use a soft brush or a damp cloth to carefully remove all caked-on clay from the outsole and midsole after each use.

Shoes feel too tight or uncomfortable

Ensure laces are adjusted properly. If discomfort persists after a break-in period, consider if the sizing is correct for your foot.

Reduced energy return or cushioning over time

The Hyper Foam may naturally compress slightly with extensive use. Ensure the shoes are properly cared for and dried to maintain material integrity.

Upper material showing premature wear

While Duraprint is durable, avoid abrasive actions beyond normal tennis play. Ensure proper fit to prevent excessive friction on specific points of the upper.

Setup, Compatibility & Care

Setup: These shoes are ready to wear out of the box. Ensure they fit snugly but comfortably, with no pinching or excessive looseness. Adjust lacing for optimal support.

Compatibility: This shoe is specifically designed for clay courts. While they can be worn on other surfaces, their unique tread pattern and cushioning are optimized for clay and may wear faster or perform sub-optimally on hard courts, grass, or indoor surfaces.

Care:

  1. Cleaning: After each use on clay, gently brush off excess clay from the sole and upper using a soft brush or dry cloth. For deeper cleaning, use a damp cloth with mild soap and water. Avoid soaking the shoes.
  2. Drying: Air dry the shoes at room temperature away from direct heat sources. Never use a dryer or radiator, as this can damage the materials.
  3. Storage: Store in a cool, dry place, preferably in a shoe bag, to protect them from dust and maintain their shape. Avoid storing in humid or excessively hot conditions.
