FAQs

Are these shoes waterproof?

The Cascadia 18 features a durable protective upper, but it is not marketed as waterproof. It is designed for breathability on the trail.

Can I use these for road running?

While you can run on pavement, the outsole lugs are designed for trail surfaces. Using them extensively on concrete will cause the rubber lugs to wear down faster.

How should the shoe fit?

You should have about a thumb's width of space between your longest toe and the front of the shoe to account for foot swelling during long runs.

Are the insoles removable?

Yes, the stock insoles can be removed to accommodate custom orthotics if necessary.

How often should I replace my trail shoes?

Generally, trail running shoes should be replaced every 300 to 500 miles, depending on the ruggedness of the terrain you typically cover.

Troubleshooting

Feeling of debris getting inside the shoe

Ensure the laces are tensioned properly across the midfoot and consider wearing gaiters compatible with the Cascadia design if running in heavy scree or sand.

Outsole losing grip on wet rocks

Check the tread for packed mud or debris build-up; use a stiff brush to clear the lugs to restore the specialized traction pattern.

Pros and Cons

Pros

  • Excellent durability due to reinforced high-wear coating
  • High-traction outsole provides confidence on technical terrain
  • Adaptable stability system keeps the foot supported on uneven ground
  • Comfortable cushioning suitable for long-distance trail runs

Cons

  • Firm midsole may not suit runners looking for extreme plushness
  • Designed specifically for trails and may feel heavy for casual street use
  • Limited to trail-focused performance geometry

Setup, Compatibility & Care

To ensure your Cascadia 18s last, keep the following in mind:

  1. Break-in Period: While ready out of the box, walk or jog for short distances to allow the upper materials to conform to your foot.
  2. Cleaning: After muddy runs, remove the insoles and wash the shoes with lukewarm water and a soft brush. Air-dry in a cool, ventilated area away from direct heat sources like radiators, which can damage the cushioning foams.
  3. Storage: Store in a cool, dry place to prevent the breakdown of synthetic materials and glues.
  4. Compatibility: These are designed for neutral to stability-seeking trail runners. They are fully compatible with aftermarket orthotic inserts if additional arch support is required.
