Full details

These trainers provide excellent water protection and long-lasting cushioning, making them an ideal choice for hikers and active commuters alike; however, users should note that the waterproof membrane may reduce breathability during exceptionally hot, dry conditions.

FAQs

Are these shoes machine washable?

It is not recommended to machine wash your trainers, as the heat and agitation can damage the waterproof membrane and adhesives. Clean by hand instead.

Can I replace the insole?

Yes, the Nova 4 features a removable EVA footbed, allowing you to swap it for a custom orthotic if required.

Is the Nova 4 suitable for winter hiking?

While the shoe is waterproof and has excellent grip, it is not insulated for extreme sub-zero temperatures. It is best suited for 3-season hiking.

Does the shoe run true to size?

The Nova 4 generally fits true to standard adult sizing. If you plan on wearing thick hiking socks, some users prefer to go up a half size.

What is the primary difference between the Nova 4 and the Traveller version?

The Traveller models often feature different upper materials, such as suede, which prioritize casual aesthetic over the synthetic mesh performance of the standard Nova 4.

Troubleshooting

Reduced waterproof performance

Check if the outer fabric is dirty, which can soak up water. Clean the exterior and re-apply a DWR treatment.

Insole slippage or discomfort

Remove the removable EVA footbed, ensure there is no debris underneath, and re-seat it firmly into the heel pocket.

Odour buildup

Remove the insoles to air dry separately and use an odour-neutralizing spray designed for athletic footwear.

Pros and Cons

Pros

  • Reliable waterproof performance for wet trails
  • Lightweight feel thanks to FloatPro foam
  • Versatile aesthetic suitable for non-trail settings
  • Excellent grip on technical surfaces
  • Includes sustainable, recycled materials

Cons

  • Waterproof membrane may feel warm in high temperatures
  • Less breathable than non-waterproof mesh alternatives
  • Requires proper care to maintain waterproof integrity

Setup, Compatibility & Care

To ensure your Merrell Nova 4 trainers last, avoid using harsh detergents that can degrade the waterproof membrane. After muddy hikes, rinse the outsoles with water and remove stubborn dirt with a soft brush. Allow the shoes to air dry naturally in a cool, shaded place; never expose them to direct heat sources like radiators, as this can damage the foam and adhesives. To maintain the waterproof properties over time, consider using a specialized DWR (Durable Water Repellent) spray after deep cleans once the original coating begins to wear off.
