How does the Shearling Boston differ from the classic Boston?

The shape and cork footbed are the same, but this version adds a shearling lining and a suede upper for warmth. The classic Boston is unlined and lighter for warm weather.

Do they fit true to size?

Birkenstock recommends its own sizing, and many owners say the medium width runs narrow. People with wide feet often go up a size or choose the wide fit.

How long is the break-in period?

Expect a few weeks of firm support before the cork footbed molds to your foot. Wearing them in short sessions first helps.

Can I wear them outside?

Yes. The rubber outsole grips pavement and the closed toe handles cool, dry days. They are not meant for rain, snow or heavy mud.

How do I clean the suede and shearling?

Brush dry suede with a suede brush and spot-clean stains. The shearling should be air-dried and brushed, not machine washed.

Are they good for plantar fasciitis or flat feet?

Many buyers with arch problems like the contoured support, but the firm footbed is not for everyone. Try them on before relying on them for a medical condition.
