The second release introduces a shearling-lined Boston clog and the collaboration’s first Arizona sandal, both featuring Etro’s signature Western-inspired detailing
Birkenstock and Etro are continuing their footwear collaboration with a second release, introducing a new interpretation of the Boston clog alongside the Arizona sandal, which joins the partnership for the first time. Following the collaboration’s runway debut in Milan and initial launch in September, the latest offering brings together Birkenstock’s functional footwear heritage and Etro’s distinctive approach to color, texture, and decorative detailing. The collection will launch globally on November 19, 2026.
The release arrives as Birkenstock concludes the Boston’s 50th anniversary year, offering another interpretation of the signature clog. Crafted from premium suede leather in a sophisticated mink colorway, the updated Boston features a sand-colored shearling lining that introduces warmth and texture to its familiar silhouette. The design retains Birkenstock’s signature footbed, preserving the comfort and functionality that have defined the style while incorporating Etro’s more expressive design language.
The collaboration also introduces a new version of the Arizona, the two-strap sandal originally designed by Karl Birkenstock in 1973 with inspiration drawn from Brutalist architecture. For this release, the silhouette is rendered in premium suede leather with a tonal nappa leather footbed, offering a refined interpretation of the house’s recognizable open-toe design. The understated material palette provides a contrast to the decorative elements that connect both styles to Etro’s aesthetic.
Western-inspired hardware serves as a defining feature across the collection. Both the Boston and Arizona incorporate exclusive buckles with matching metal strap ends, complemented by rivets bearing Etro’s Pegasus emblem. The outsoles continue a visual detail introduced in the collaboration’s first chapter, combining Birkenstock’s traditional bone-pattern tread with Etro’s signature Paisley motif. The integration of these elements creates a connection between the two brands while maintaining the distinct identities of their respective designs.
The second release builds on the partnership’s exploration of heritage footwear through a contemporary fashion perspective. By combining Birkenstock’s established silhouettes and functional construction with Etro’s material treatments and ornamental references, the collaboration offers a balance of practicality and decorative expression. The addition of the Arizona also expands the partnership beyond the Boston, introducing another of Birkenstock’s most recognizable designs to the collaboration.
The second release of Birkenstock by Etro will be available worldwide beginning November 19 through etro.com and 1774.com, as well as selected Etro and Birkenstock boutiques and retail partners. The latest chapter continues the brands’ shared exploration of craftsmanship and design heritage, bringing Etro’s signature aesthetic to two enduring Birkenstock silhouettes.
