Merrell Promorph Trainers - Black - UK 9

While the trainers can be used on roads, they are primarily designed for trail running. The outsole is optimized for off-road traction, which may not be ideal for road use.

Use a damp cloth to wipe off dirt and debris. Avoid using harsh chemicals or washing them in a machine.

Standard running socks are recommended. Choose socks that wick away moisture to keep your feet dry.

No, the trainers are not waterproof. They are designed for breathability. Water-resistant versions may be available.

The lifespan depends on usage and care. Regular trail runners may need to replace them every 300-500 miles. Proper care can extend their lifespan.

Warranty information can be found on the Merrell website or provided at the point of purchase.

Store them in a cool, dry place away from direct sunlight.

Ensure you have selected the correct size. Try loosening the laces or consider going up a half size.

Clean the outsole regularly to remove dirt and debris. If the problem persists, the outsole may be worn and need replacement.

Use Cleansport NXT™ treatment to help with odor, and allow shoes to air dry after use.

Repair any tears in the material. Avoid washing the trainers in the washing machine.
