Ensure you have selected the correct UK size. For minor tightness, try loosening the laces. If persistent, consider alternative models with a wider fit.

Cushioning materials can naturally degrade. Ensure the shoes are not being used for excessively slow paces or on abrasive surfaces that could wear down the foam and plate prematurely.

Ensure proper lacing to avoid pressure points. If discomfort persists, the shoe's design might not be ideal for your foot mechanics or the specific demands of your longest runs; consider a more cushioned or stable option for those purposes.
