ASICS Gel-NYC Trainers - Black Graphite Grey - Size 11.5

While the Gel-NYC trainers offer good cushioning for general wear, they are not specifically designed for marathon running. For long-distance racing, ASICS offers specialized running shoes with advanced technologies for performance and support.

The trainers should feel snug but not tight. There should be about a thumb's width of space between your longest toe and the end of the shoe when standing. Ensure your heel doesn't slip excessively.

It is not recommended to machine wash ASICS Gel-NYC trainers. Machine washing can damage the materials, cushioning, and adhesives. Hand washing with a soft brush and mild soap is the preferred method.

The 'Gel' refers to ASICS' signature GEL technology for shock absorption, and 'NYC' likely signifies inspiration or a design aesthetic associated with New York City, often implying urban style and functionality.

The primary benefit of ASICS' GEL technology is its excellent shock absorption. It helps to reduce impact on your feet and joints during movement, providing enhanced comfort and cushioning.

These trainers are not designed to be waterproof. They offer protection against light moisture but are not suitable for heavy rain or wet conditions.

Ensure you are tying a secure double knot. Consider using laces made of a material with more grip, or replacing the current laces if they are worn.

Break in the trainers by wearing them for short periods initially. Ensure you are wearing appropriate socks. If discomfort persists, double-check the sizing or consider adding a heel insert.

For minor scuffs, try cleaning with a damp cloth. For more significant marks on synthetic or leather parts, a specialized shoe cleaner or polish might be effective. Always test on an inconspicuous area first.
