FAQs

Can I use these shoes on hard courts?

These shoes are designed specifically for clay courts; using them on hard courts may result in premature wear of the specialized tread pattern.

What is the primary benefit of the Hyper Foam?

Hyper Foam provides enhanced energy return and shock absorption, helping to keep your feet feeling fresh during long matches.

How should I clean my K-Swiss clay shoes?

Wipe the upper with a damp cloth and use a soft brush to remove clay from the outsole. Do not submerge or machine wash.

Do these shoes run true to size?

The K-Swiss K-Frame Speed Rublo follows standard adult sizing. If you prefer a thicker court sock, consider the fit against your standard athletic shoe size.

What is the K-Frame structure for?

The TPU K-Frame is an internal support component located under the forefoot to prevent unnecessary movement and increase lateral stability.

Troubleshooting

Feeling instability during side-to-side movements

Ensure the laces are tightened properly to engage the internal TPU K-Frame structure and prevent foot roll.

Accumulation of clay in the sole pattern

Use a dry, soft brush to clear the grooves between matches to maintain consistent grip levels.

Pros and Cons

Pros

  • Excellent lateral stability from the TPU K-Frame technology
  • Highly responsive Hyper Foam midsole for energy return
  • Durable yet breathable upper construction
  • Optimized specifically for clay court performance

Cons

  • Not suitable for hard-court play due to specialized tread
  • Requires break-in period for optimal comfort
  • Limited to clay-specific court usage

Setup, Compatibility & Care

To ensure peak performance, verify you are playing on a clay court surface, as the outsole pattern is engineered to grip loose particles. For care, avoid machine washing your shoes, as this can degrade the specialized midsole foam and structural adhesives. After playing on damp clay, allow the shoes to air dry naturally in a cool, well-ventilated area—avoid direct heat sources like radiators, which can warp the upper mesh. Use a soft-bristled brush to gently remove caked-on clay from the outsole treads after every match to maintain traction.
