ASICS GEL-CUMULUS 16 Trainers - Grey - Silver - UK 5

The ASICS GEL-CUMULUS 16 are primarily designed for training and general wear, offering good cushioning for shorter to medium-distance runs. For serious marathon training, consider models specifically engineered for long-distance running which may offer more advanced support features.

Ensure there is about a thumb's width of space between your longest toe and the front of the shoe when standing. Your heel should feel secure and not slip excessively. Try them on with the type of socks you typically wear for athletic activities.

It is not recommended to machine wash these trainers. Machine washing can damage the GEL cushioning, adhesives, and upper materials. Hand washing with mild soap and water is the preferred method for cleaning.

The GEL technology in the midsole provides excellent shock absorption, reducing impact on your feet and joints during exercise and everyday wear. This leads to enhanced comfort and helps in recovery.

For optimal performance and injury prevention, athletic trainers are typically recommended to be replaced every 300-500 miles of running, or when you notice significant wear on the outsole or a loss of cushioning and support.

Tonal laces means the laces are the same or a very similar color to the main color of the shoe, contributing to a unified and streamlined aesthetic.

Adjust the tonal laces for a more personalized fit. Ensure you are wearing appropriate athletic socks. If discomfort persists, consider if the size is correct.

Clean the rubber sole thoroughly to remove any accumulated dirt or debris that might be affecting traction.

Ensure the laces are not tied too tightly, allowing for better air circulation. The open-hole mesh is designed for breathability; consider if the environmental conditions are exceptionally hot.

This can sometimes occur with new shoes. Ensure all parts are dry. If the noise persists, try wearing thicker socks or consult product support.
