ASICS Gel-Challenger 15 Trainers - White - UK 12

The ASICS GEL technology is designed to provide superior shock absorption, reducing impact on your feet and joints during movement, which enhances comfort and helps prevent fatigue.

The Gel-Challenger 15 Trainers are optimized for training and court sports. For long-distance running like marathons, specialized running shoes with different cushioning and support features are recommended.

Ensure there is a thumb's width of space between your longest toe and the front of the shoe when standing. The heel should feel secure without slipping, and there should be no pinching or excessive pressure on any part of your foot.

No, it is not recommended to machine wash these trainers. Washing can damage the materials, adhesives, and the structural integrity of the shoe. Cleaning with a damp cloth is the preferred method.

The durable rubber outsole is designed for optimal traction on various indoor and outdoor court surfaces, as well as general training environments. It provides reliable grip on dry and reasonably clean surfaces.

The lifespan of the trainers depends on the frequency and intensity of use, as well as how they are cared for. For regular training, they typically offer good durability, but signs of wear on the outsole and cushioning may indicate it's time for a replacement.

Ensure the correct size is being worn. Break in the shoes gradually by wearing them for short periods initially. Check that socks are appropriate for athletic activity.

Clean the outsole to remove dust or debris that may be affecting grip. The shoes may be worn out and require replacement if the tread is significantly diminished.

This is common with new footwear. Wear them for short durations during non-strenuous activities to allow them to mold to your feet. Avoid machine washing.
