FAQs

Are these shoes waterproof?

The MTL SpeedArc Peak is designed primarily for breathability and drainage, which is standard for competitive trail racing, and it is not explicitly categorized as waterproof.

Can I use these for road running?

While they can be worn on roads for short distances, the specialized outsole and aggressive lugs are optimized for soft, technical trail surfaces and will wear down prematurely on hard pavement.

How do I determine the correct size?

The MTL SpeedArc Peak follows standard adult sizing. It is recommended to size up by half a size if you prefer extra room for foot swelling during long-distance trail efforts.

How often should I replace these shoes?

Depending on the intensity of your training and the terrain, high-performance trail shoes typically provide optimal support for 300 to 500 miles.

Are these suitable for wide feet?

The fit is engineered for a secure, athletic hold, which may be more anatomical and slim-fitting than traditional lifestyle sneakers.

Troubleshooting

Feeling discomfort or hot spots during long runs

Adjust the tension of the laces to ensure a secure but not overly tight fit, or consider swapping the insole for a custom orthotic if needed.

Outsole losing traction in extreme mud

Ensure the tread is fully cleaned of debris and caked mud after each use to maintain the full depth of the lug profile.

Pros and Cons

Pros

  • Elite stability suitable for technical mountain trails
  • Extensive development and testing by professional athletes
  • Exceptional traction for varied, unpredictable surfaces
  • Lightweight build designed for speed and personal records

Cons

  • May feel too firm for casual, everyday walking
  • Technical design may require time for runners to adjust
  • Limited to trail-specific environments rather than mixed road-to-trail use

Setup, Compatibility & Care

To ensure the longevity of your MTL SpeedArc Peak trainers, start by ensuring a secure lacing fit that keeps the heel locked in place without restricting circulation. Because these are technical trainers, it is recommended to gradually integrate them into your rotation if you are accustomed to shoes with more cushioning. To clean, remove excess dirt with a soft brush after every run. If the shoes become muddy, rinse them with lukewarm water and mild soap, then allow them to air dry naturally away from direct heat sources, such as radiators, which can damage the technical adhesives and materials.
