The second chapter of Birkenstock by Etro puts shearling inside the Boston clog and brings the Arizona into the collaboration for the first time. The two styles share one color, Mink, and one hardware idea: an Etro Western buckle with matching metal strap ends.
Both pairs sit in Birkenstock’s 1774 line and keep the anatomically shaped cork-latex footbed that anchors every version of the collaboration. The 1774 name reaches back to the year that tradition begins, and every product in the line is made in the company’s German workshops.
The collaboration first appeared on Etro’s Fall/Winter 2026 runway in Milan, and its first release followed in September with an embroidered Boston and a fringed Gizeh. It’s the collaboration’s second release. Chapter two turns quieter, trading embroidery and fringe for texture: shearling, suede and nappa in a single Mink tone.
What changes is the surface: the leathers, the lining, the hardware.
The Boston, lined for cold weather
The Boston keeps its closed-toe silhouette and its single strap, cut here from full-grain suede with a sand-colored shearling lining. The clog dates to 1976, and this version marks its fiftieth year with warmth rather than embroidery.

Its footbed is fully covered with tonal nappa leather and lined with shearling, so the softness runs from the strap to the sole. A Pegasus-branded rivet fastens the strap, and Etro lists the clog in a narrow width for sizes 35 to 40, a fit worth checking before the shearling settles. The strap ends match the buckle’s metal. The lining does the talking.
The Arizona joins in suede and nappa
The Arizona arrives as a two-strap sandal in the same Mink suede, carrying a Western buckle on each strap. Its footbed edges are covered in chocolate-colored nappa leather, a darker tone set against the pale suede. Birkenstock sells the pair for women and men.

The chocolate nappa also appears as detailing across the upper. That ties the sandal’s palette to the first chapter’s taupe and chocolate. The silhouette itself dates to 1973. The nappa runs chocolate, the suede runs Mink, and the two tones do all the decorating instead of any printed pattern.
Mink keeps the pairing calm.
Paisley, saved for the sole
Paisley, the pattern Etro is known for, never appears on the uppers of either shoe in this chapter. It sits in the EVA outsole instead, where Birkenstock’s bone-pattern tread is cut with paisley details that only show from below.

Chapter one’s embroidered Boston cost $690 and its fringed Gizeh $730, which makes this second chapter the cheaper way into the collaboration. Both pairs carry ETRO and BIRKENSTOCK branding on the footbed and ship in Arnica-motif packaging with a branded dust bag. The motif stays hidden in use. Arnica is the motif name Etro gives the packaging print.

Buy the Boston if your clogs work hardest in winter, because the shearling lining changes how the shoe wears every single day. Skip both if suede care already tests your patience, or if narrow fits rule out the clog.
