ASICS Gel-Challenger 15 Trainers - White - UK 11

These trainers are designed for court sports and training, providing agility and traction. For marathon running, dedicated running shoes with specific cushioning and support are recommended.

You should have about a thumb's width of space between your longest toe and the end of the shoe. The heel should feel secure without slipping, and there should be no pinching or excessive tightness around the width of your foot.

It is not recommended to machine wash these trainers. Machine washing can damage the materials, adhesives, and cushioning technology. Hand clean with a damp cloth as per the care instructions.

The GEL technology is specifically engineered to provide excellent shock absorption, helping to reduce impact on your feet and joints during high-impact activities.

The lifespan of athletic shoes varies based on frequency and intensity of use. For optimal performance and injury prevention, it's generally recommended to replace trainers every 6-12 months, or when the cushioning feels less effective and the outsole shows significant wear.

No, these trainers are not waterproof. They are designed with breathable materials for comfort during athletic activity, which means they are not resistant to water.

Ensure laces are tied correctly and snugly. Consider using thicker socks for a tighter fit. Check if the shoe size is appropriate; a shoe that is too large can cause slippage.

While GEL technology is durable, its effectiveness can diminish with prolonged heavy use. For optimal performance, consider replacing trainers after significant wear, typically 6-12 months depending on usage.

Many athletic shoes require a break-in period. Wear them for shorter durations initially and gradually increase wear time. Ensure you are wearing appropriate athletic socks.
