FAQs

Are these shoes suitable for winter hiking?

The GORE-TEX membrane offers waterproofing and breathability. While suitable for wet conditions, they are designed as hiking shoes and may not provide sufficient insulation or grip for deep snow or icy conditions without additional winter-specific gear.

How long does the break-in period typically last?

The break-in period can vary but generally involves wearing the shoes for several short hikes over a week or two until they feel fully conformed to your foot shape.

Can I machine wash these hiking shoes?

No, machine washing is not recommended as it can damage the materials, adhesives, and waterproof membrane. Hand wash with a damp cloth and mild soap as per the care instructions.

What is the main benefit of the terracare® leather?

Terracare® leather is produced sustainably in Germany and offers high quality, durability, and stability while minimizing environmental impact.

How do I re-waterproof the shoes?

Use a spray or cream specifically designed for leather hiking boots with GORE-TEX. Apply evenly after cleaning and allow to dry fully.

Are these shoes good for wide feet?

The 3D Memo Foam offers some adaptive comfort, but the fit is based on a standard last. It is recommended to try them on if possible, as individual foot shapes vary.

Troubleshooting

Feet feel wet despite GORE-TEX

Ensure laces are tied correctly to seal the tongue and that no water has entered from the top opening. Check for damage to the GORE-TEX membrane. The shoe may be saturated if not dried properly after prolonged exposure to water.

Soles feel slippery on certain surfaces

The Vibram sole provides excellent grip, but some very smooth or wet surfaces (like polished rock or ice) can reduce traction. Ensure the sole is clean of mud or debris, which can affect grip.

Discomfort or hotspots after a short time

The shoes may need a longer break-in period. Ensure you are wearing appropriate hiking socks and that the lacing is adjusted correctly – not too tight or too loose.

Leather appears dry or stiff

Apply a leather conditioner or waterproofing treatment specifically designed for nubuck leather and waterproof membranes. This will restore moisture and suppleness.

  • Durable construction with high-quality leather.

Setup, Compatibility & Care

Setup: These shoes are ready to wear out of the box but benefit from a short break-in period. Wear them for shorter walks to allow the materials to mold to your feet.

Compatibility: Suitable for use on most hiking trails, including forest paths, gravel tracks, and moderate rocky terrain. Not recommended for extreme mountaineering or ice climbing.

Care:

  1. Cleaning: After each use, brush off loose dirt. For deeper cleaning, use a damp cloth and mild soap. Avoid harsh detergents.
  2. Drying: Allow shoes to air dry naturally at room temperature. Do not place them near direct heat sources like radiators or fires, as this can damage the materials and adhesives.
  3. Waterproofing: Periodically treat the leather with a suitable waterproofing spray or cream to maintain its water resistance and condition. Ensure the product is compatible with GORE-TEX membranes.
  4. Storage: Store in a cool, dry place when not in use. Avoid prolonged exposure to direct sunlight.
