Nike Reactx Infinity Run 4 Prm Road Running Shoes - Purple - UK 4

Yes, they can be used for walking, but they are optimized for running.

Refer to the Nike size chart and measure your foot. These shoes are size UK 4.

While these shoes are primarily designed for road running, they can be used for light cross-training activities.

It is recommended to replace running shoes every 300-500 miles or when the cushioning starts to degrade.

Use a damp cloth and mild soap to clean the shoes. Avoid using harsh chemicals or machine washing.

Use running socks, which are made of moisture-wicking materials and provide comfort and support.

Nike offers a warranty against manufacturing defects. Check the Nike website for details.

Ensure the correct size (UK 4) is being used. If the shoes are still too tight, consider loosening the laces or consulting the Nike size guide.

Allow the shoes to fully dry after running. Replace the shoes when the cushioning becomes noticeably less effective, typically after 300-500 miles of use.

Try double-knotting the laces or replacing them with new ones.
