FAQs

How do I determine the correct shoe size?

Measure your foot length from the heel to the longest toe. Refer to the provided size chart and choose the size that matches your measurement. If your measurement falls between two sizes, select the larger size for a more comfortable fit.

What is the difference between 'Foot Length' and 'CM' size?

The 'Foot Length' is the direct measurement of your foot in centimeters. The 'CM' size indicated on the shoebox or label may differ and is a standard shoe sizing conversion. Always use the 'Foot Length' measurement to select your size from the provided table.

Can these shoes be machine washed?

No, machine washing is not recommended. Hand clean with a damp cloth and mild soap if necessary, and air dry.

Are these shoes suitable for running marathons?

These sneakers are designed for lightweight, all-day comfort and light athletic activities. They are not intended for high-performance or marathon running, which requires specialized footwear.

What is the main cushioning technology used?

The shoes feature Bounce midsole cushioning, which provides responsive support and comfort for everyday wear.

What material is the upper made of?

The upper is made of mesh, which provides a lightweight and airy feel for enhanced breathability.

Troubleshooting

Shoes feel too tight

Loosen the laces and adjust for a more comfortable fit. If the issue persists, consider if a larger size is needed, following the foot measurement guide.

Soles feel slippery

Ensure the rubber outsole is clean and free from excessive dirt or debris that could reduce traction. The outsole is designed for everyday surfaces; performance on highly polished or wet surfaces may vary.

Discomfort after extended wear

Verify that the correct size has been selected using the provided foot measurement chart. Ensure laces are tied appropriately – not too tight, not too loose.
