FAQs

Are these shoes suitable for hard courts?

These trainers are specifically designed for clay courts. While they might offer some grip on other surfaces, their optimal performance and durability are achieved on clay. Using them on hard courts may lead to faster outsole wear.

How do I clean the clay off the shoes?

After use, brush off loose clay with a soft, dry brush. For more stubborn dirt, use a slightly damp cloth. Avoid using soap or harsh chemicals.

What makes the K-Frame structure beneficial?

The innovative TPU K-Frame under the forefoot provides enhanced stability, allowing for quicker, more agile movements and better support during sharp directional changes on the court.

What is the benefit of the Hyper Foam midsole?

Hyper Foam is a new cushioning technology that offers exceptional energy return and superior shock absorption, helping players maintain their performance levels with less fatigue.

How long will these shoes typically last?

Durability depends on frequency of use, playing style, and court surface. However, the Duraprint upper and clay-specific outsole are designed for longevity under normal clay court playing conditions.

What is the significance of the Andrey Rublev collaboration?

The shoes were developed in collaboration with ATP star Andrey Rublev, meaning they incorporate features and performance characteristics that meet the demanding standards of professional tennis players.

Can I wear these shoes for running or other sports?

While these shoes offer good cushioning and support, they are optimized for the specific movements required in tennis, particularly on clay courts. They are not recommended for general running or other sports.

Troubleshooting

Shoes feel too tight or uncomfortable

Ensure you have selected the correct UK size. Wear the shoes for short periods initially to allow them to break in. Adjust the lacing to find a more comfortable fit.

Traction feels reduced on court

Clean the outsole thoroughly to remove any caked-on clay or debris. Ensure the court surface is dry, as dampness can affect grip even with specialized shoes.

Premature wear and tear on the outsole

Verify that you are using the shoes on appropriate court surfaces (clay). Using them on hard courts or abrasive surfaces will significantly accelerate outsole wear.

Upper material feels stiff

The Duraprint upper is designed for durability and may feel initially stiff. Continue to wear them for short sessions; the material will become more pliable with use.

Setup, Compatibility & Care

Setup: The K-Frame Speed Rublo Clay trainers are ready to wear straight out of the box. Ensure you have the correct UK size for a comfortable and secure fit. The lacing system should be adjusted to provide a snug feel without restricting circulation.

Compatibility: These shoes are specifically designed for clay courts. While they may offer some grip on other soft surfaces, their optimal performance and tread wear are maximized on clay.

Care Instructions: To maintain the performance and longevity of your K-Frame Speed Rublo Clay trainers:

  1. Post-Match Cleaning: After each use, gently brush off any excess clay or dirt from the outsole and upper using a soft brush or a dry cloth.
  2. Damp Cleaning: For tougher dirt, use a slightly damp cloth. Avoid using harsh detergents or abrasive cleaners, as these can damage the materials.
  3. Drying: Allow the shoes to air dry naturally at room temperature. Do not place them near direct heat sources like radiators or in direct sunlight, as this can cause the materials to warp or crack.
  4. Storage: Store the shoes in a cool, dry place when not in use. Consider using shoe trees to help maintain their shape.
