Product Information

Full details

The Crank Brothers Stamp BOA cycling shoes are designed for serious mountain bikers who prioritize superior pedal connection and off-bike walkability. Featuring the high-friction MC2 rubber compound and a precise BOA micro-adjustment system, these shoes provide exceptional grip and a customizable, secure fit for all-day riding. While they excel in technical terrain and hike-a-bike sections, users should note that the focus on breathability and flexibility may feel less rigid than full-carbon race shoes.

FAQs

Can these be used with clipless pedals?

No, these are specific flat-pedal shoes and do not feature a cleat mounting interface.

How should I store these between rides?

Store in a cool, dry place out of direct sunlight to prevent rubber oxidation and material degradation.

Are these shoes waterproof?

They are not waterproof; the ventilated windows and mesh panels are designed for breathability, meaning they will allow water to pass through.

How do I replace the BOA lace if it breaks?

The BOA Fit System features a replaceable lacing kit. You can contact the manufacturer or visit the BOA website for specific replacement instructions for your model.

Are these true to size?

The Stamp series generally fits true to standard cycling shoe sizing, but it is recommended to reference the brand's size guide relative to your UK foot size.

Troubleshooting

BOA dial feels stiff or jammed

Clean debris from the dial mechanism using compressed air or a soft brush and ensure no grit is caught inside.

Foot slipping inside the shoe

Verify the heel dots are clean and use the BOA dial to tighten the fit further, ensuring the tongue is centered under the laces.

Pros and Cons

Pros

  • Excellent grip on flat pedals due to MC2 rubber
  • BOA system allows for easy mid-ride adjustments
  • Highly comfortable for hike-a-bike sections
  • Durable TPU reinforcements for trail debris protection
  • Integrated heel dots provide a secure, slip-free hold

Cons

  • Less stiff than dedicated competitive racing shoes
  • Perforated mesh may let in water during wet conditions
  • Not suitable for clipless pedal systems

Setup, Compatibility & Care

The Stamp BOA shoes are optimized for flat pedals, particularly those within the Crank Brothers Stamp series to maximize the tread pattern interface. When setting up, ensure the BOA dial is fully engaged; turn clockwise to tighten and pull the dial out to release tension quickly.

To clean, remove loose mud with a soft brush and wash with lukewarm water and mild soap. Avoid using high-pressure sprayers or harsh detergents that could degrade the rubber compound or the synthetic mesh. Allow the shoes to air dry naturally in a well-ventilated area away from direct heat sources, such as radiators, which can compromise the structural integrity of the EVA foam and adhesive bonds.
