Birkenstock Boston Clog vs Birkenstock Boston Shearling

Both are the same Boston clog, so the real choice is the footbed lining. The standard Boston uses a suede-lined cork footbed that breathes and works year-round. The Shearling adds a sheepskin lining for warmth and a softer step, which suits cold rooms and bare feet but runs hot in summer. Owners of both praise the arch support and the adjustable buckle; the shearling version draws more complaints about the lining matting down with wear.

• Choose the Boston if you want one clog for all seasons, breathable wear and the classic suede footbed that holds up over years.
• Choose the Boston Shearling if you feel the cold, plan to wear it indoors in winter or want a plush step against bare feet.
