Concepts and Birkenstock add another chapter to our close partnership. Since 2014, we’ve stayed true to Birkenstock’s beloved Boston model, fitting it with an array of luxury leathers and fabrics, such as thick felt and rich suede. For this latest installment, we’re revisiting the custom grooved leather created for our last project, and contrasting it’s original bright lime treatment with a total blackout.

The premium quality black grooved leather sits atop Birkenstock’s exquisite leather footbed, stamped with Concepts logo. Adorned with black leather strap, buckle and outsole, this unique iteration of Birkenstock’s German-made clog is the perfect footwear to comfortably transition your wardrobe from the tail end of winter into Spring.

The Concepts x Birkenstock Boston Noir will be released Friday (3/8) on CNCPTS.COM at 11:00AM (EST). Sizes 36-46 will be available for $250.
