You probably don't need an introduction to what Birkenstock's Boston Clog looks like. But this time, ADER ERROR isn't touching the silhouette at all — instead, they've added a single flap to the upper, stitched down with fine thread. That's it. No second design move.
This ADER ERROR x Birkenstock 1774 Boston Clog carries over the original's long-standing wooden last shape, with the cork footbed kept as is. The only change is a folded panel stitched onto the upper with understated stitching — arguably the only element on the entire shoe that could be called "design."
The color is actually what steals the show here. The upper comes in "Ultra Blue" suede, the same shade that's previously shown up on Birkenstock's Arizona sandals and Kyoto slides — a bit of electric blue the brand has clearly taken a liking to lately. Paired with the cork sole, it strikes a balance between understated and eye-catching at the same time — a contradiction that's become something of a signature move for Birkenstock in recent years.
