The Birkenstock Boston SFB VL with a narrow footbed is a revised version of the Birkenstock classic from 1977 and offers a comfortable fit with its practical slip-on silhouette, the soft suede upper and the typical cork-latex footbed . A non-slip EVA outsole, a soft inner lining and an adjustable strap with a pin buckle increase comfort. The khaki colorway and an embossed logo on the side ensure a minimalist look.
