Birkenstock Boston with natural shearling lining is a joy to wear. Comfortable right out of the box for all day wear and very warm. The natural suede leather is so soft and quickly conforms to your foot a long with the Birkenstock famous cork sole. The shearling lining is thick and plush so going up a size might be a better fit. The Classic Birkenstock Boston design never goes out of style. I have received many compliments on my shoes and answered a few question concerning the comfort. Yes, Birkenstocks are very comfortable and supportive shoes to wear. I have been wearing Birkenstock for well over 50 years. I still can wear my very first pair. ??
