FAQs

Are these shoes true to size?

Birkenstock sizes are generally consistent, but the wide, ergonomic shape may feel different than standard athletic shoes. Refer to the UK sizing guide to ensure a correct match for your measurements.

Can I wear these in the rain?

It is recommended to avoid heavy rain, as water can damage the cork footbed and cause the leather to stiffen or warp.

How do I clean the leather upper?

Use a soft, dry brush to remove dust and a slightly damp cloth for light surface stains. Avoid using harsh chemical cleaners.

Is the footbed removable?

No, the signature cork-latex footbed is built directly into the sole of the sandal and is not designed to be removed or replaced.

Are these unisex?

Yes, the Boston model is designed as a unisex shoe, suitable for both men and women provided the correct size conversion is selected.

Troubleshooting

Footbed feels too hard or uncomfortable initially

This is normal for new Birkenstocks. Wear them for 1-2 hours at a time inside your home until the cork and leather soften to your foot's shape.

Buckle feels loose or too tight

Adjust the strap to the appropriate hole and ensure the prong is securely seated. If the fit changes over time due to leather stretching, simply tighten the buckle one notch further.

Pros and Cons

Pros

  • Excellent anatomical arch support for long-term comfort

  • Versatile design suitable for a wide range of casual environments

Cons

  • The cork footbed is initially firm and requires a break-in period
  • Leather uppers are not waterproof and require protection in wet conditions
  • Limited cushioning compared to modern foam-based athletic footwear

Setup, Compatibility & Care

To ensure your Birkenstock Boston shoes last for years, proper maintenance is essential.

  1. Breaking In: Wear them for short intervals initially to allow the cork to adapt to your foot shape.
  2. Leather Care: Use a quality leather conditioner periodically to keep the material supple and prevent cracking. Avoid submerging the leather in water.
  3. Cork Maintenance: Inspect the cork edges; if they appear dry, apply a light coat of cork sealer to prevent crumbling.
  4. Storage: Keep your shoes in a cool, dry place away from direct heat sources like radiators, as excessive heat can damage the cork and leather.
