Rick Owens did it again and designed a third collection for BIRKENSTOCK that celebrates the synergy between avant-garde and wearable fashion. The elongated strap - the core element of the RO designs - is subtly emphasized with black rivets. Rotterdam, the third style of the collection, impresses with an elegant interplay of materials - polyurethane meets high-quality leather and is accentuated with matt black rivets. The jet black leather provides serious elegance, while Arizona and Boston also convince with an interpretation of coated leather.
