Merrell Agility Trail Trainers - Grey - 3.5

While they are comfortable enough for occasional road use, they are specifically designed for trail surfaces and their lugged outsole will wear down faster on asphalt.

These are standard adult sizes; it is recommended to measure your feet in the afternoon when they are at their largest and allow for a thumb's width of space at the toes.

No, machine washing can damage the adhesive and the waterproof membrane. Use a damp cloth and mild soap instead.

They are ideal for moderate terrain including woodland paths, gravel tracks, and packed dirt trails.

Yes, waterproof shoes typically have less airflow than non-waterproof versions, which is a trade-off for keeping your feet dry in wet conditions.

Check that the laces are tightened correctly to secure the midfoot; if the issue persists, the trail surface may be too steep or loose for these specific lugs.

Ensure the upper material is clean and undamaged; check if water is entering from the ankle cuff due to deep puddles or high water levels.

Re-adjust the lacing tension and ensure you are wearing moisture-wicking synthetic socks rather than cotton, which can bunch up.
