Asics Netburner Ballistic Ff 4 Trainers - Grey - UK 11

These trainers are specifically designed for indoor court sports like volleyball. While they offer good cushioning, they may not provide the specific support or durability needed for running on harder surfaces.

It is recommended to try the shoes on, preferably at the end of the day when feet are slightly swollen. Ensure there is a thumb's width between your longest toe and the front of the shoe, and that the heel does not slip.

FlyteFoam technology provides exceptional lightness and superior bounce-back/durability, offering significant cushioning without adding weight.

No, machine washing is not recommended as it can damage the shoe's structure and materials. Hand wash gently with mild soap and water.

AHAR (ASICS High Abrasion Rubber) is a durable compound used in areas of the outsole where extreme wear is likely. It provides enhanced durability and grip compared to standard rubber.

The FlyteFoam cushioning is designed for durability. With proper care and use for intended activities, it should maintain its responsive properties for a significant period. However, its lifespan can be affected by frequency of use and playing conditions.

Try wearing thinner socks or consider if the size is appropriate. For minor tightness, continuous wear over time may loosen them slightly. If significantly tight, it may be worth exploring a half-size larger.

Ensure the AHAR rubber outsole is clean. Dust or debris can reduce traction. Clean the soles with a damp cloth. If the issue persists, the outsole may be worn down.

The breathable design should help. Ensure laces are not tied too tightly, which can restrict airflow. Consider wearing moisture-wicking socks.

FlyteFoam cushioning may feel firmer initially. It typically softens and conforms to your foot with regular use over several play sessions.
