Birkenstock Boston Shearling Unisex

Same contoured cork footbed as the rest of the Boston line — arch cradle, deep heel cup, toe bar — wrapped in a shearling lining that makes it a winter house clog. The cork still needs its break-in; the shearling doesn't change that. Trade-off to know: the lining adds warmth but also bulk around the foot, and the fixed footbed won't accept custom orthotics.
