Please Note: Birkenstock uses their men's narrow width last to make the medium width footbed on certain women's styles. For that reason, the box may indicate narrow width even though the shoe is medium width. This exceptionally sophisticated yet highly casual version of the Boston clog, a classic BIRKENSTOCK model, comes with a shaft in soft suede. The robust and extremely lightweight EVA sole is very flexible, facilitating a rolling motion that is good for feet and body. Anatomically shaped cork-lagex footbed. Upper and lining are suede. Flat heel. Made in Germany.
