What makes an enduring design? Is it about a specific aesthetic? Maybe it is about the choice of materials. Or perhaps it is the craftsmanship that goes into making a piece. Whatever it may be, one thing is certain: good design doesn’t chase a moment—it quietly outlasts it.

For German footwear brand Birkenstock, good design is defined by three core values: tradition, quality, and function. It lasts because it solves a real problem well and resonates with people across generations. A perfect example of that is one of its iconic styles: the Boston.

Designed by Karl Birkenstock and launched in 1976 as the Kork-Clog, the Boston features the brand’s innovative cork-latex footbed, developed to support natural walking. It marked a significant departure from the heavy, rigid wooden platforms of that era, balancing the protective feel of a shoe with the ease of a slip-on. By supporting the foot’s natural shape rather than forcing it into a restrictive mold, the pair allows the toes to spread and flex naturally with every step.

Another plus point is its gender-neutral sensibility, reflecting Karl’s take on minimalism and his interpretation of the Brutalist aesthetic. Over time, however, the Boston became a canvas for different styles. While designers, artists, and brands have all put their own spin on the clog, its signature silhouette and anatomically shaped footbed have remained unchanged.

As the Boston celebrates its 50th anniversary, Birkenstock aims to spotlight not just its beginnings but also its many reinterpretations. Last June 12, the brand brought its archival and collaborative pieces from Germany to Manila, chronicling the evolution of the pair—from how it is made to the many looks it has donned through the years.

“What we want to celebrate is what’s good for your feet,” Eveline Chua, Birkenstock managing director for Southeast Asia and Down Under, tells Manila Bulletin Lifestyle. “That is why the brand continues to evolve. We don’t see ourselves as a fashion or trendy brand. We see ourselves as heritage- and craft-driven. It is all about function and quality.”

Displayed at Power Plant Mall in Makati City are some of the Boston’s most notable metamorphoses, including collaborations with luxury shoe label Manolo Blahnik, Japanese retailer Beams, Belgian painter René Magritte, and supermodel Heidi Klum, among others.

The pop-up also allowed Filipino fans of the brand to put their own spin on their Boston pairs through artworks by Mark Wy and Keed, as well as crocheted pieces by Ilang Ilang. Visitors also had the opportunity to discover how the iconic pair is made, from the tools used to the leather chosen for its upper.

Beyond the exhibit, Birkenstock also forged a partnership with the Tourism Promotions Board. Together, they launched “The Philippines by Foot,” a year-long initiative that encourages intentional walking while discovering the stories, communities, and cultural landmarks that make every step worth taking.

“We want to make this campaign meaningful. We managed to find the right moment to bring this initiative first to Manila, and then to the rest of the cities in the Philippines,” Eveline says. “The campaign also encourages people to spend time walking, to create meaningful moments, and to stay grounded. We are celebrating the feet. Walking is what we do every single day. It is about going back to basics.”
