FAQs

Are these shoes compatible with non-Crankbrothers SPD pedals?

Yes, the Mallet SpeedLace is compatible with any brand of SPD cleat by adjusting or removing the included Match shim.

How do I clean the mesh panels if they get muddy?

Use a soft brush to gently remove dried mud from the perforated mesh, then wipe with a damp cloth.

Are the cleats included in the box?

Yes, the shoes come with pre-installed Crankbrothers Match shims and cleats ready for setup.

Can these shoes be used for road cycling?

While technically possible, they are optimized for MTB pedals and may be heavier and stiffer than dedicated road shoes.

What is the purpose of the internal heel dots?

The dots are designed to increase friction and grip against your socks, preventing heel lift during pedaling strokes.

How should I store the shoes after a wet ride?

Remove the insoles, stuff the shoes with paper to absorb moisture, and let them air dry in a room-temperature environment.

Troubleshooting

Difficulty clipping in or out of pedals

Check if the Match shim needs to be adjusted or removed based on your specific pedal brand to ensure proper engagement depth.

Heel slipping while pedaling

Ensure the SpeedLace is tightened sufficiently and the strap is securely fastened; verify that the internal heel dots are clean and free of debris.

Laces coming loose

Ensure the laces are fully tucked into the dedicated lace pocket on the tongue after tightening to prevent them from being pulled during the ride.

Pros and Cons

Pros

  • Versatile SPD cleat compatibility with any brand
  • Quick and easy adjustment via the SpeedLace system
  • Excellent ventilation for hot-weather riding
  • Secure heel hold prevents energy loss
  • Includes pre-installed Match shim and cleat for immediate use

Cons

  • Stiff construction can be less comfortable for long periods of walking
  • Requires specific pedal interface to gain maximum benefit
  • Lace pocket can become difficult to access if clogged with thick trail mud

Setup, Compatibility & Care

Setup is straightforward due to the included Crankbrothers Match shim and pre-installed hardware. If you are using non-Crankbrothers cleats, simply remove the grey Match shim to achieve the correct depth and engagement height. For cleaning, use a damp cloth to wipe away surface dirt. If the shoes become soaked or heavily covered in mud, remove the insoles and allow the shoes to air dry in a well-ventilated area away from direct heat sources, which can damage the synthetic materials and adhesives. Regularly inspect your cleats for bolt tension to ensure they remain secure on the sole.
