Asics Gel-Kayano 12.1 Trainers - White/ Grey - UK 6.5

The Rearfoot and Forefoot GEL technology is designed to provide excellent shock absorption, reducing impact on your feet and joints during movement.

While they offer good cushioning, the Gel-Kayano 12.1 are primarily designed for comfort and stability in general wear and light training. For marathon running, specialized racing shoes might offer better performance characteristics.

It's best to spot clean them with a damp cloth and a mild cleaning agent. Avoid machine washing or fully immersing the shoes in water.

FLUIDRIDE technology in the midsole provides a combination of cushioning and responsiveness, offering a smooth transition from landing to take-off.

These specific trainers are listed as being for 'Male' gender. While fit can be subjective, women may need to consider a significant size difference or opt for a women's specific model if available, as sizing often differs.

The upper is constructed from a combination of layered synthetic leather and open mesh underlays.

The product information states they are made in Extra EU.

Loosen the laces and adjust the fit. If the tightness persists, consider if this is the correct size for your foot. The lace-up system allows for some adjustment.

Ensure the laces are tied correctly for proper support. If discomfort continues, the shoe's specific cushioning or fit may not be ideal for your foot type or activity. Ensure you are wearing appropriate socks.

This can sometimes occur with new shoes. Try wearing them for a few more sessions to break them in. If the noise persists, ensure there is no debris trapped in the sole or laces.
