Merrell - Agility Trail - Grey - 5

While you can run on roads, the 3mm lugs are optimized for trails and may wear down faster if used primarily on abrasive asphalt.

Merrell sizes generally follow standard UK sizing; however, it is recommended to leave a thumb's width of space at the front, as feet tend to swell slightly during trail runs.

Yes, the insoles are removable and replaceable if you need to use custom orthotic inserts.

The waterproof barrier is designed to keep external water out while allowing some moisture vapor to escape, though it will naturally be less breathable than non-waterproof mesh versions.

FloatPro foam is highly durable, typically providing support for 300-500 miles depending on your weight, running surface, and intensity.

Ensure your laces are tightened correctly to prevent water from entering through the ankle collar, and check that your socks aren't wicking moisture from the outside.

The 3mm lugs are designed for moderate terrain. If you frequently encounter extreme mud, try to choose flatter, less saturated paths to maintain better traction.

New EVA and FloatPro foams can feel slightly firm initially. The material will naturally soften and break in after the first 10-20 miles of use.
