ASICS Gel-NYC Trainers - Black Graphite Grey - UK 12

While the GEL technology offers good cushioning, the Gel-NYC is primarily designed as a versatile trainer for general athletic activities and casual wear. For marathon-specific needs, ASICS offers specialized running shoe lines.

Refer to the ASICS sizing chart, which typically correlates UK sizes with foot measurements in centimeters or inches. It's often recommended to try them on in person if possible, as fit can vary between models.

It is strongly advised not to machine wash these trainers. Machine washing can damage the materials, adhesives, and the GEL cushioning system. Hand cleaning with a damp cloth and mild soap is the recommended method.

The primary benefit of ASICS' GEL technology is its exceptional shock-absorbing capability, which helps to reduce impact on your feet and joints during physical activity, promoting comfort and reducing fatigue.

The standard fit is designed for average foot widths. If you have wider feet, it is recommended to check for specific wide-width (2E, 4E) versions or try them on to ensure a comfortable fit.

The lifespan of any footwear depends heavily on usage frequency, intensity, and care. With proper care and moderate use, these trainers are built for durability, but regular users might consider replacement every 300-500 miles of running or when cushioning and support noticeably decrease.

Ensure laces are adjusted properly. Consider wearing them for short periods initially to break them in. If discomfort persists, consult the sizing guide or try a different size.

The GEL technology is designed for longevity, but performance can be affected by excessive wear. If cushioning feels significantly diminished, it may be time to consider a replacement pair.

Gently clean the affected area with a damp cloth and mild soap. For stubborn marks, a specialized shoe cleaner may be used cautiously, following product instructions.
