PUMA MagMax Nitro Trainers - White/Silver - Size UK 4

Yes, the extensive NITROFOAM™ cushioning makes them highly suitable for marathon distances, providing sustained comfort and reducing fatigue.

While comfortable, they are optimized for forward motion on roads. For gym workouts involving lateral movements or heavy lifting, dedicated cross-training shoes might offer better stability.

Refer to PUMA's official sizing chart. It is recommended to measure your foot length and compare it with the chart. For these trainers, the UK size 4 is noted.

NITROFOAM™ provides a lightweight, responsive, and highly cushioned feel, offering an exhilarating bounce and superior shock absorption.

PUMAGRIP is engineered for superior grip across various surfaces and conditions, offering enhanced durability and traction compared to standard rubber outsoles.

For optimal performance and cushioning, it is generally recommended to replace running shoes every 300-500 miles (480-800 km) or when the cushioning feels significantly diminished.

No, the mesh upper is designed for breathability and is not waterproof. They are suitable for dry to mildly damp conditions.

This is normal for shoes with advanced cushioning technology. Wear them for short periods initially to allow them to break in and mold to your feet.

Ensure the PUMAGRIP outsole is clean and free from debris. While PUMAGRIP offers excellent traction, extremely slick surfaces can still pose challenges. Proceed with caution on very wet or icy conditions.

Adjust the lacing system. Ensure the knitted tongue is positioned correctly and not bunched up. If discomfort persists, the shoe may not be the right fit for your foot shape.
